okay its been over a month since the last time i've worked on my engine. (94 3.0)... my baby still aint running. heres what i did so far,... new heads, gaskets, fuel pump, fuel filter, regulator, circuit opening relay, spark plugs, cap and rotor. i've got fuel, spark, and compression yet it still sputters and dies out... i checked then double checked and even tripple checked the timing belt making sure its lined up perfect... so it aint my timing... vacuum lines are all connected properly... im wondering if it could be the intake manifold/plenum being clogged up... i never had it cleaned.. ive been reading threads about using a can seafoam to clean it but the engine needs to be running... my engine starts up but i have to keep pumping the gas or else it shuts down... does this sound like a solution to my problem?, please help... thanks

if the truck won't run, cleaning the plenum won't help.
I don't have the v6 so I can't help you much with specific issues, but there is something wrong besides gunk in the intake if the truck won't run.

Make sure your plug wires are correct. Simple mistake to be made.

fuel injectors?...you didn't say you checked/cleaned those. what about the fuel lines?
