My buddy just swapped a 92 12v into an 88 crew cab Chevy, motor runs good and starts easy, but when you try to rev it up it sputters and won't take the fuel, it pops and smokes alot???? It ran fine in the Dodge??? The pump has been played with. Someone suggested the fuel pump could be bad? I can post a video of the truck so you guys have a better idea what I mean.
