1993 S10 z vin. I am at a loss for the reason this has no spark and no
fuel I have replaced the fuel pump and ecm and still it does not run.
I probably did not need a fuel pump but in haste I replaced it since I
did not see fuel delivery at the throttle body. Then I found that it
also had not spark. My conclusion was that the ecm was out after all
the truck has 150k on it. At this point I can find no reason for the
problem other than the possibility that the prom is bad.
Anyone have any ideas that may help me pinpoint the problem.

no fuel prim at the injectors and no spark when cranking the motor?
I have a similar problem, although it is intermittent. I haven't replaced any
parts as truck always starts eventually. Had it towed to my dealer once and it
started as soon as it was let down from the tow truck. Frigging frustrating.
I hope someone on the group has a brilliant idea. :-)

OK, sounds good. Since I'm not a mechanic, and don't want to pay $50.00 an hour
to have it checked out.
Where are the grounds that need to be checked?
Is there a ground at the gas tank that will require dropping the tank?
I have a Chilton's manual but it doesn't give locations for grounds.
I've checked the obvious grounds but where might there be grounds in out of
the way places?

Hey, I'm just looking for some help.
I'm more mechanically reclined, than inclined. :-)
I can identify a ground wire, but wanted to know where there might be some in
out of the way places. As I stated in my previous post, I've checked all I
