My 99 Tahoe that I did a 383/4l80e with 0411 pcm was running good and I was able to put about 700 miles on it then it just shut off and would not crank, after sitting for 5-10mins it would crank so I thought coil so I got a used coil and ignition module from my uncle put it on and drove the crap out of it for about 700 miles then Saturday I was driving back from church and it backfired and shut down and hasn't had any spark since, I replaced the ign coil, crank position sensor, cam pos sensor, ignition module and distributor cap and still no spark, I just double checked the distributor and it's set dead perfect according to the service manual but still no spark, replaced the ignition switch and still no change. I had an issue with the crank position sensor earlier and found out it was too far from the triggerwheel because that blocks been line bored and honed so I checked my scanner and I'm getting rpm signal, u habe 12v power at the crank and cam pos sensors, coil and ign module, can someone please help me figure out this thing because I really need it get to work right now I'm having to share my daughter's truck with her
