I need a little advice for my truck. It was
running fine then all of a sudden it just
stopped and wouldn't restart. I got it home, i
checked for fuel and it's getting to the
motor. So then I checked for spark, and no
dice. I took the distributor apart and had the
parts store test the module, it was fine. Then
I replaced the coil in the distributor because
of heavy corrosion, but it still has no spark.
The motor turns over just fine, and it is a
350. Any ideas on where I should go from
check all fuses and relays especially the ecm (computer) relay.
Disconnect the coil and put a test light between the 2 contacts, then crank the engine a look for a pulsating light, if you have a light then replace the coil, if you don't then check the wiring from the distributor to the coil, as you have already had the pickup and module tested and they were good. As I'm not there to see, the only other option is if this truck has the old ESC module, you can find that out if it says ESC on the tailgate, if it does then the best thing to do is to retro fit it to standard solid state GM module not an ESC unit.

Check the cap and rotor. On those the rotor will burn threw the center were it makes contact with the coil. Take the rotor off and look underneath it and if you see a burn mark (carbon black area in the center) replace the cap and rotor, the rotor at least. So you had the module tested, did you look at the pole piece? (the coil pick-up). There are two wires that run to it and one usually breaks off.
