Any suggestions where to start or what to look for?P0440 is a "large" EVAP system leak. Which is kind of good news, should make it easier to find than a P0442 (small leak).

Spec is 60-66 psi; if it's a little bit low you can get intermittent no-starts or possibly random/multiple misfire codes. If you upgrade to the MPFI (8 individual injector) setup it seems like the operating pressure is a bit lower. Fuel pressure seems to be less critical at this point because you're not depending on the 60-66 psi that the central injector setup requires to force open the poppet valve junk.Thank you guys for the prompt replies.
The following day after encountering that P0440 code, prior to taking off to work, I cleared the CEL and took off. Code never came up again. I've been driving my truck locally and it drives fine. I hear the air pump running when I turn on the truck. Must of been pumping dirt and moisture sitting in the pipes and hoses prior plugging it back in. Who knows how long it was unplugged for.
Only code I'm getting is a Cyl 2 misfire. Sometimes it turns to a multiple cyl. misfires. I'm 100% cyl 2 is the root cause.
I'm still on the factory injectors. Been looking at upgrading to the new model but I would hate to dump $370 and for my misfire to still be present.
I'm getting a test fuel pressure gauge on Friday, starting with that. I've read pressure should be 60psi with the key to on position.
