ya thats what i was talking about. relay was a big word for almost 1am. lol. u said your not getting any fuel to the engine? did u try the valve thing (cant think of what its called right now) on the fuel rail. shrader valve!! have some one push down on it and crank the key. it should be about 40 psi and it will spray. but i cant remember if you said you allready tried or not. sorry if u did.

ya man the only thing i can think of is pump or your pick up line. those were the two things advised to me. i had help with the lock ring. its better if you have a girl lay on a creeper next to you and push the pump while u situate the lock ring. lol it helps a ton.

haha yeah man if only there were alot of girls who are willing to get a little dirty or get under a car Id definitely do that. but yeah I tried to check all that stuff. Im almost gonna resort to the white flag and have a mobile mechanic fix it (a trustworthy one of course) hehe
