Have you read the other p300 thread I gave you ....

These trucks prefer ac delco for ignition parts ...

 

i used ac delco plugs and wires and a dorman distributor assembly

 

When you changed icm did it come with a small packet of heat sink grease. I seem to remember a ten page thread on a p300 that finally ended with the persons module not coming with the grease. It transfers the heat to the heat sink. This guy tossed every thing but his kids at it and came down to that. Something missing from a box and 3.49 from Radio Shack.

 

if i was u i would take the icm back to were u got see if they can test it to make sure its good.
and r u sure ur not a 180 degs out on the distributor

 

yep the icm came with the heat transferring grease i plastered it over the back and screwed it to the heat sink

 

yep the distributor is installed properly but i'll double check it tommorrow to make sure it is

 

Hey Jon, with changing the distributor you might want to do a read on this.

make sure the distrib. is in time and not a tooth off. check to see if timing between crank and cam right and not slipped.

 

yep as soon as i get off work ill check it out and make sure i got everything installed proper thanks for the help and ideas so far

 

i went through the trouble shooting link u posted for p0300 and checked for all the items listed contaminated fuel, foulded or damaged spark plugs, damaged distributor cap, restricted exhaust. The only ones i havent check are the vcm grounds and the EGR valve and idea how i can check the grounds or the location of them? and i also double checked the installation of the distributor assembly and all is well with that.
