You've been a great help in the past helping me diagnose car problems

wiring harness because it was melted and shorting out , it has been

Another question , can this problem cause other damage ? I don't
think it can since it's just not getting gas to that cylinder but ...

Thanks , but we've already determined that the injector is OK . We
swapped it to a different cylinder , the code did not move with the
injector . Also , I applied 12V to the injector in question , it clicked
as it should - I pressurized the inlet side while momentarily applying
power and residual fuel flowed from it . It is in a different cylinder
now and functioning properly . If I had an oscilloscope I could check
for a voltage pulse ... my voltmeter isn't fast enough to catch it .
