Long story longer, "friend" overheats his truck (about 300K on it) and it won't start the next morning, he says it blew the head gasket (97 f-150 5sp). So he buys a wrecked truck ('98 F-150 auto) that still runs. We swap the engines and the "new" one won't start in his truck. It tries- acts like the firing order is wrong but that's been checked. It has a slightly low fuel pressure (32 PSI) with key on and starting fluid doesn't help it start at all. All the sensors and FPR stayed with the engine. It got dark and we were tired so I gave up on it for tonight... It isn't throwing any codes as of yet. We did swap the coil since we had one right there and his old one was newer with no luck. Questions: If we swap the PCM from the auto f-150 to the manual one the engine should run, right? Even though there is no auto tranny there, it should still start? Also, if the inertia switch was tripped I wouldn't have fuel pressure at all? I haven't even checked the fuses on this thing, it wouldn't start, we played around for 10 minutes and I went in the house... pissed. Any ideas?
