time to check the grounds around your intake manifold and to see if you got your fuel lines mixed up.

i tried the fuel lines both ways.... i got the feed line coming in the oposite side of the fuel rail from the pressure regulater npow.. i thought all my grounds was hooked up there was 2 on the intake manifold and two on the head that i see but i can double check them again tonight and i dotn know what to do after that ........ also when i put the timing chan cover on the kit that had the new seal also had a rubber o ring and another metal seal with rubber arond it for the oil hole.....was the o ring and the metal seal both suppose to be in there? becaue i couldnt get them to fit correctly

yeah there is an oring that is attached to metal and another oring that's flying solo behind the front cover. Uhm, what do you mean they couldn't fit correctly? That's for oil though, not for your situation with no fuel. You're positive your injectors aren't firing?

i just took the timing cover off but when i put it on i put a new oring that was attached to the metal back in but i couldnt figure out where just the plain rubber o ring went does it go on the same oil hole with the metal one because i it didnt look liek it was fitting right having a the oring with the metal agianst the rubber o ring. i am pretty sure the injectors arent firing because there is fuel in the fuel rail but none in the cylinders thanks what did you man that the oring is solo behind the cover .. thanks

oh you'd know if it weren't getting any oil pressure from the sounds lol.

by solo i meant no metal attached to it.

might be time to bust out a noid light to double check that the injectors aren't firing. if they're not firing, you're gonna be in for pulling a multimeter and checking continuity from the injector plugs to the ecu harness.

when you pulled the front cover, you saw two openings behind the front cover for oil pump o-rings. one is a groove that's cut into the block. The regular rubber o-ring fits in that one. The other one with the metal backing fits into the other hole.

Manual? Auto?

Anyways this is going to sound dumb but I got bit by this and felt like a fool after (when I noticed it a couple of minutes later) Did you unplug your starter for any reason?
