We have replaced EGR valve, IAC valve, TPS sensor, pickup coil, distributor, ICM. First the truck was just starting to bogg with throttle, then it started to stall unless the throttle was applied, cut off cat , slight change, replaced egr and tps, to no effect. Then replaced IAC, stalled couple of times, then quit. No spark, replaced distributor, ICM, and ignition switch. Now recieve spark, but only cranks and not starts. I am baout to go ballistic over this truck becaus eI really need to make a living. Whatever answer works will be rewarded. thanks a whole heck of alot.

Good old Bill

Look at prior post, still think distributor was installed on exhaust stroke not compression stroke. Its confusing as Hell, but is as simple as it gets. Forget its a 6 cylinder engine or 8cyls or 4 cyl. Concentrate only on the front cylinder #1. Compression stroke please. Can't tell you how many times I have been on the exhaust stroke. Been there and done that!
