i have a 1992 k1500 4x4 zr2 off road with a 5.7

i parked it at work and when i went to leave it would just turn over and not start.

i noticed i couldn't hear the fuel pump, so i put a new fuel pump relay in, then a new fuel pump.

then i checked for spark and im not getting spark.

so i replaced the ignition module thats in the distributer cap.

still no spark or fuel pump...

im stumped....

 

Have you checked your fuses & relays? sounds like a loose wire,fuse or computer problem.

 

Have a look at your CPS.(Crank Position Sensor)

 

make sure the cable from the coil is good....

 

all the fuses and relays are good.

monday in going to use a computer and check and run some codes and see what that has to say.

but for now i'll keep you posted on it.

 

Can you measure the voltage on your fuelpump , coming from the battery? (I know its kind of almost impossible to get to it ) . There should be some wires going in there. If you dont get any reading there, then well...its fuses or relais or ...

 

i ran a hot wire to pump will run now but will not run off relay
