I'm working on a 95 1500 that was brought to me because of a battery draining issue. I charged the battery and tried to start it to move it so I could begin to diagnos the drain and it wouldn't start. It was drove to my house the night before. It has since held a charge and cranks over fine, just won't start. It doesn't have spark or fuel.

I checked and swapped both fuel and asd relays and they are fine. I can jump power to fuel pump at the relay and get the pump to run. It gets power to both relays in constant 12 volt and key on hot terminals it just seems as though the computer isn't completing the circut. I have checked all fuses and they seem good.

anybody have any ideas where to look next?

Tomorrow I'm gonna double check everything. It seems to me that it should be a fuse or relay, but I can't find anything wrong. Are their fuseable links anywhere that would control these? I didn't see any.

 

As far as the battery draining, check thglove box light to see if it's on continuously.

Good luck with your ride.

 

I also don't have a check enge light when key on.........maybe pcm bad? Fuse is good, anybody have pin outs for the computer so i can see if its getting juice?

thanks
