I have a Chevy Kodiak dump truck that I am trying to fix.

Pictures of the truck and carburetor are he

http://igor.chudov.com/tmp/Chevy-Kodiak/

Supposedly, and I believe the person who told me the story because I
know him very well, a pump gasoline inside the gas tank went bad on
it. A while ago, tank was disconnected and we put it back when we got
the truck.

Truck sat outside for 2 years without any further work.

We bought a new pump from NAPA.

The truck cranks, but would not start without fuel added to carb.

If I remove the nut holding the line near the carb, then gas pours out
of it when the pump in the gas tank is activated. So, gas gets to the
carburetor.

If I pour gasoline in the carburetor, the engine starts great. It
also runs great when the engine runs and I continuously add a small
stream of gas to the carb.

However, without that stream, it does not get any gas.

There are two electric valves in the carb. If my guy cranks the motor
and presses the gas pedal, I see some drops of gasoline, but not
nearly enough for this Chevy 454 engine.

Any ideas what could be wrong? Carb cleanout and rebuild necessary?

thanks

Yup. But first, remove the contaminated gasoline
from the tank, pump and lines. Safest would be
to remove the gas tank and have it de-rusted,
cleaned and lined.

Onboard computer bad ?

Looks like throttle body injection (TBI), lots of stuff to go wrong.

Yes, if it is TBI it does not have a carburetor, it has a throttle body
which only superficially looks like a carb. The TBI setup has an in-tank
high(er) pressure fuel pump and two fuel injectors in the throttle body.
You can check to see if the injectors are being opened by the PCM with
"NOID" lights which you can usually borrow from an auto parts place
(with deposit). If the injectors are getting driven by the PCM they may
well be clogged/stuck, I don't believe a set of those injectors is all
that expensive. If they are not getting driven by the PCM there could be
issues with sensors like crankshaft or camshaft position.

What model year is it? I had a 1990 FS Blazer with the TBI 350 and the
TBI 454 was an option. I *think* I still have the manuals for it around.

This does seem to be TBI (not that I know much) and the engine is a
Chevy 454!

If you have anything on it, I would love to get a copy or a scan!

Thanks a lot!

Yeah, that's not a carb, it's Chebby's style of EFI.

Ig, get the service manual on it and go from there. I wonder if they
had computer access ports on that truck. If so, find out which reader
can see it and look for the troubleshooting codes.

Now that you have the truck and trailer for it, you can buy a
loader/backhoe and be able to move it around.

Jim, where is the filter that you have in mind? On the carb itself?

Like I said, I did disconnect the gas line where it enters the carb,
and fuel came out of the disconnected line when the fuel pump is
activated.

So, if you mean a clogged filter in the carburetor, I guess it is
possible, but if you mean some inline filter on the lines leading to
the carburetor, I do not think that it is possible.

After two years of setting dry and unattended, I'd guess the carb float
is at best stuck and other issues as well. I'm thinking these would
still have a manual accelerator pump as well.

All in all, a good carb cleaning and perhaps a kit are likely called for...

dpb, here's where I am lost.

The carburetor, visibly, does NOT have a bowl. It does, however, have
those electric valves on top. It might have a bowl, but its location
is not obvious or visible.

Almost certainly it is the TBI - Throttle Body Injection - early fuel
injection setup.

I hadn't looked at the closeup pictures before, but just did after
thinking about the year. It's one of the hybrid injection systems.
I've had a couple but never had to work on one so forget the earlier
thoughts posted--they're not pertinent to these.

I think the phrase is "throttle body injection" for looking for information.

If I were to hazard a complete guess, it would be after two years idle
the injectors are plugged. How to attack them, specifically, I don't
know, sorry.

How do they work, do they create pressure, or are they just valves,

A fuel injector is just a solenoid actuated spray nozzle. The in-tank
pump provides the fuel pressure and the pressure regulator regulates
that pressure sending excess fuel back to the tank via the return line.

Yeah, the age got me thinking later and so I went and did look--it is,

.. Except it is not a carb. You have a TBI engine - throttle body
injected. What year is the puppy? If it is pre-1996 a good code
scanner can tell you everything you need to know, if you know what you
need to know - if you know what I mean.

The two "solenoids" are fuel injectors - and the other part - the
metal hat with the adjuster screw in it is the fuel pressure
regulator. See if the connection to one injector has 12 volts on one
side any time the key is on and it a 12 volt lamp (test light, noid
light, or 194 side marker lamp in socket) connected across the
connector flashes when the engine is turned over. If you have 12 volts
and the light flashes the injectors or regulator are likely the
problem. If not, you have electrical problems. Ther will be a "shrader
valve" somewhere on the fuel line. You need to verify your fuel
pressure. It should be roughly 10-12 PSI if my memory serves
correctly.

If it is pre 1996 you can get the trouble codes off the check engine
light by shorting terminal A to B on the aldl connector. That's the
two end terminals of the top row on the right side.

You should get a code 12 - flash - - flash flash.

Look for a code 33 or 34 (map sensor), 54 (fuel pump circuit) 55 (bad
ECM) 21 or 22 (throttle position switch), or 14 or 15 (intake air temp
sensor) Any other codes should not prevent it from starting. Also be
sure you ARE getting spark. No spark usually means no trigger for the
injectors as well.

A somple injector function test is a stethoscope - you should hear
them go "tick-tick" when the engine is cranked.

Also, if I need to clean them with ultrasound, should I submerge them
completely?

need to know - if you know what I mean.

The two "solenoids" are fuel injectors - and the other part - the
metal hat with the adjuster screw in it is the fuel pressure
regulator. See if the connection to one injector has 12 volts on one
side any time the key is on and it a 12 volt lamp (test light, noid
light, or 194 side marker lamp in socket) connected across the
connector flashes when the engine is turned over. If you have 12 volts
and the light flashes the injectors or regulator are likely the
problem. If not, you have electrical problems. Ther will be a "shrader
valve" somewhere on the fuel line. You need to verify your fuel
pressure. It should be roughly 10-12 PSI if my memory serves
correctly.

If it is pre 1996 you can get the trouble codes off the check engine
light by shorting terminal A to B on the aldl connector. That's the
two end terminals of the top row on the right side.

You should get a code 12 - flash - - flash flash.

Look for a code 33 or 34 (map sensor), 54 (fuel pump circuit) 55 (bad
ECM) 21 or 22 (throttle position switch), or 14 or 15 (intake air temp
sensor) Any other codes should not prevent it from starting. Also be
sure you ARE getting spark. No spark usually means no trigger for the
injectors as well.

A somple injector function test is a stethoscope - you should hear
them go "tick-tick" when the engine is cranked.

Do you think that I should try to clean them in an ultrasonic cleaner?

If so, what liquid should I use for cleaning?

Also, if I need to clean them with ultrasound, should I submerge them
completely?

i

Page 4-23 of the docs I scanned say that the fuel injectors should not
be submerged in any type of liquid solvent or cleaner.

Carb cleaner... nasty stuff, keep it off your skin,

Yea, when I bought my POS honda, it ran a bit rough, I took out the
injectors, soaked them in a bath of carb cleaner over night, reinstalled
with new seals and it ran 100% better. I bought one of those pails of
cleaner with a basket in it like this http://tinyurl.com/6s3hdqv but I
don't remember it being that much. It was 5+ years ago

You're lucky they were steel and it was the "environmental" bull****.
If you had soaked aluminum carb parts in a REAL (Chem Dip) dip tank
overnight, you'd have come back to a nearly empty basket the next day.

Nasty ****, mon, and exactly what's needed to do the job right and

Supposedly, and I believe the person who told me the story because I
know him very well, a pump gasoline inside the gas tank went bad on
it. A while ago, tank was disconnected and we put it back when we got
the truck.

Truck sat outside for 2 years without any further work.

We bought a new pump from NAPA.

The truck cranks, but would not start without fuel added to carb.

If I remove the nut holding the line near the carb, then gas pours out
of it when the pump in the gas tank is activated. So, gas gets to the
carburetor.

If I pour gasoline in the carburetor, the engine starts great. It
also runs great when the engine runs and I continuously add a small
stream of gas to the carb.

However, without that stream, it does not get any gas.

There are two electric valves in the carb. If my guy cranks the motor
and presses the gas pedal, I see some drops of gasoline, but not
nearly enough for this Chevy 454 engine.

Any ideas what could be wrong? Carb cleanout and rebuild necessary?

thanks

2 years on a dry carb means you will need a kit and clean and rebuild
the carb.

Should have looked at the pictures. That is NOT a carb. It is fuel
injected. If you installed a pump for a carbed truck you have the wrong
pump. If you installed the injected pump then you need to flush the
injectors with cleaner.

As an aside, how many commercial vehicles do you have to own before
the State and/or Feds consider you a Motor Carrier (it does not need
to be the primary purpose of your business for you to fall under that
designation)? What legal resposibilities up to and including Homeland
Security do you need to follow once they decide that is one of your
hats?

Keep an eye on that stuff or it will bite you.

One. Especially if the vehicle requires a CDL to drive it. (both of the
latest vehicles Iggy has posted fall into that area.)

It'll depend on what he does with them as well...there's a difference
between private motor carrier and for-hire as well as exempt (I don't
know all the loopholes for exempt, farm is one and schoolbus is another;
whether there's an escape clause iggy can get into is worth looking for
altho I kinda' doubt it). But, he may have to worry about interstate if
he is selling over eBay and shipping stuff hauled even if
auctions/purchases are all within local--the end destination can be the
gotcha'.

Fortunately, the farm catches us so haven't worried about the details
much here but as noted iggy needs to be cautious doesn't inadvertently
get caught in the painful parts...

Don't think that would make any helpful difference. That's in the
category of a private motor carrier but wouldn't relieve him of the
actual situation of hauling goods for resale which is where is potential
real gotcha' might be concerning interstate rules coming into play that
are more onerous to comply with as far as recordkeeping, etc., etc.,
etc., ...

Since igy is a merchant and those trucks are for sale at the right price
he is a motor vehicle dealer right ? Those trucks are just inventory.
