starting issue.....help please

[jbmobbs]

ok since last night my truck has given me an issue.

every time i start it it either fires right up or i have to hold the key for like 3 or 4 seconds

the other part is.....after i fire it up it runs like crap, kinda like a miss or timing is off. after a few seconds it smooths out and runs great. iv given it new plugs, wires, cap, rotor button, coil, injectors,

am i missing something here?

I can definitely hear the miss. Your fuel pump sounds really loud too. I don't know if it's just because your phone was sitting on the tailgate or what but it didn't sound like mine. I would consider fuel issues since they're not spark related, so any of the TB sensors, o2s, or fuel pump. Start with fuel pressure check at the rails to verify good pressure then go from there.

It definitely ain't hitting on all cylinder on start up. Any smoke? I gotta wonder if one of the injectors is leaking down overnight.

That would explain long start up but what about it continually missing?

I think i need to do the same on mine. When starting it cranks like that. I *** thinking battery because it's 5 years old but I'm starting to wonder. Doesn't really stumble but i prob better check just to be sure
