You need to run an accurate fuel pressure test on these vehicles. They need
around 60PSI to start. If it's not there, they refuse to fire. Fuel pump
failure is COMMON.

If you're creative, you can substitute a $80 Delco EP381 into the module.

On the 97 Blazer & Jimmy, the fuel pump relay is inside the glove box
behind a cover on the upper-left corner. On my 97 Jimmy, there are
three relays. The left-most is the fuel-pump relay and the right-most
is the daytime running lights relay. Not sure what the third one is.

I am sure by now (two months later) you have figured this out, but
since I had the same difficulty, now it is here for others to find.

I am now getting ready to drop the tank to figure out if there is juice
to the pump itself. $300 for a pump - ouch!

Hi;

Thanks again for the help regarding the transmission. Your replies
helped us
prevent the tranny guy from sucking about $1000 out of our pocket.
Turned out
to be the 3-2 shift "assembly" whatever that exactly means.

Anyway, now it won't start. Cranks fine and has spark but no fuel.
There are
three relays I can see under the hood. Does anyone know which one is
the fuel
pump relay ?, or if it is in an alternate location ? None of these
three click
when the ign is turned on. I've been looking around the web just for
a simple
pictorial of the underhood components and can't seem to find one
after an hour
of Googling.

I'm leaning away from the pump itself because there were absolutely
no problems
with engine performance, it ran like a raped ape. It kept it up after
a long
run too, after the tranny was fixed of course.

From what I've been reading I'll need to find the ECM2 fuse and said
relay to
troubleshoot this. Even the location of the fuel pump test terminal
would help.
I considered even testing at the oil pressure sending unit, but I'm
pretty sure
that'll be hard to do, this thing is pretty cramped.

From what I've gleaned from the web it could even be the ignition
switch,
something I'll not rule out yet because this was a shut it off and no
restart
situation. Had to get a tow.

Anyway, I am familiar with how the modern fuel system works so I
don't need a
tutorial on it, what I need is specific info. I realize the relay I
seek could
be under the dash, in the glove box or who knows, in these newer cars
it could
be in the frickin steering column (a little joke).

Actually I was wondering if there is indeed a better forum for such
questions.
I've kicked around in some other groups that seem related to this
type of
question, but none seem to be so fast moving or responsive as SER. In
fact I
don't seem to see a NG with participants with the depth and breadth
of
knowledge expressed here. I actually Googled "groups" and couldn't
find what I
need. I even Googled "images" and got nothing, just a picture with
pointers,
like that in a Haynes book would do the trick. Not to be found.

Thanks in advance.
