turns over for about 4-8 seconds before it finally cranks up. but if i cycle the key on and off 3 times it cranks right up all electrical/ ignition parts r less than 6 months old. and i replaced the fuel pump about 4 months ago. ??? before i replaced all this stuff it always fired right up. could i have gotten a bad fuel pump?? any help is appreciated.

When you replaced the fuel pump, did you also replace the fuel pressure regulator that sits on top of the fuel pump? A leaky FPR is the most common cause of the symptom you're having.

it was included in the pump. i put a fuel rail gauge on it and the fuel pressure bleeds off almost immediatly when i turn it off. i think i may have a bad fuel pump. facepalm. and banghead.

I would definitely suspect the FPR as the source of that problem before I'd think of the fuel pump.
