Ignition issue I think.

I have 1991 Chevy Cheyenne 3/4 ton with a 350ci enigine. The truck has 152000 miles on it. The other day my wife was driving to work and it acted like she didn't give it enough gas, died, and wouldn't start back up. I went into the hood and saw that there was fuel coming out of the injectors and spark coming from the coil when the truck was turned over. I have recently replaced the plugs, cap and rotor. Today I replaced the ignition module that is located on the distributor and it still didn't start. Money is starting to get tight and I need to find the problem. I just don't know where to go from here. I thought about the wires, but I wouldn't think it would just not even try to start if one or two were bad and the rotor is just a metal strip so not really an issue there. What do you think?

Hello there, As you were saying, youre truck is getting fuel. Also are you getting spark from the coil on youre distributor. Also has the fuel filter been changed. Also I would take the dist. Cap off see if it spins while the engine is beening turned over. Also are you getting check engine light on. If youre dist. Cap isn't turning you got a timing chain broken,

Good Luck.

I am getting fuel out of the injectors and the fuel filter was changed about two months ago. When I checked to see if there was spark from the coil I checked it at the coil NOT on the end of the coil wire which is why my next step may be to get a new coil wire and try that. I have turned the engine over with the cap off and the rotor turns. I don't know about the internal workings of the distributor, but I know there is a "trigger" mechanism. Could the trigger being faulty cause no spark to get to the plugs?

Sounds to me youre coil is not producing a spark, I would recommend checking all youre wiring harnesses as well, Around the dist. (Cuts & shorts).
Could have a weak or fail ignition Distb.

Good Luck.
