2.8 30v NO START HARD START
 

I've been having trouble starting my car for a while now usually 5 seconds of cranking sometimes starting right up. I replaced mass air flow sensor, replaced both valve cover gaskets with spark plug well gaskets, seafoamed crankcase, fuel tank and through vacuum line, replaced spark plugs and most vacuum hoses.
My car is still hard to start and today woudn't start at all. Removed spark plugs and all of them were wet with oil on the tip electrode part. I figured that's the problem but the spark plug valve cover gaskets weren't leaking into the well.
I cleaned the plugs and changed some plug wires around.
Car started very erratic and wanted to stall, I had to press the gas pedal a couple of times and got some white smoke out the back with fuel smell, Prob a misfire......

WHats going on here??? could it be bad wires? (just ordered new ngk wires right now) or fuel pump??

Help would be GREATLY appreciated.
Thank you

get the codes pulled. If its misfiring, then swap coilpacks around, scan again and see if misfire follows...

I don't have a scanner but last time I checked at autozone I had P1476 and P0306 if that helps...

did you do any troubleshooting after getting those codes? you definitly have a misfire, but im thinking you also have a big vacuum leak, or a bad Leak Detection Pump. Try either using a smoke machine to see where the vacuum leak is, or pressurize the system with the car off and see if you can hear any air escaping and where from. If no vac leaks, then i suspect you may have a bad LDP

what are the symptons of a bad LDP or a vacuum leak going to or from the LDP? Would it cause the misfires, or my car car having problems starting? Something tells me it could be the PCV causing the oil on my plugs.

Anyone knows where the PCV valve is located on the 2.8 30v and how to diagnose it?
