Hello everyone...
Really could use some help with this one. My 1998 C2500 5.7 Vortec. 340,000 miles, I was driving home from work truck running perfect. Without notice the engine shuts down, I drift off the road and tried to restart.. No go, I cycled the key and did hear the fuel pump prime up, The pump is 1 year old, AC Delco. So the engine cranks but no start. No CEL, and never had any lit. I have replaced the Crank sensor, ign coil, ignition module, and the module in the distributor, distributor, battery and ECM. I thought about maybe it jumped time, would that cause a no spark condition? I am open for assistance. I have tried ether, again no spark, but tried anyway. pulled plugs and checked them. Compression is good, fuel pressure is 60psi+. I have 12 volts going to all the modules, fuses are good, relay's are good as well. No spark anywhere.. I am stumped.
