yeah, its a 88 camaro 305, with TBI, when it actually does start, i hear this weird click nosie behind the dash and it seems that the fuel pump boosts in presure"i can hear it"...and my fuel pump it quite loud...??could this be a valve, or electric problem, or what? and sometimes when i turn the car off, it wont quit running and after about a minute, it finally shuts off...i just bought the car about a month ago, and i just dont get it because it runs fine when its actually running...sound strong and idles perfect???

you should try to keep everything in one thread. it is easy to hit the "post a new topic" when trying to hit "post a reply". done that a few times myself, but catch it when it asks for a new topic when all i want to do is reply. maybe the moderator can move this over to your other thread, or you can just post it over there.

you don't plan sincerity.
you have to make it up on the spot.

wanna hear about 20 years ago when i was too smart to know any better?

There should be two fuel rails - one for each bank of injectors. The fuel rail sits on top of the injectors, supplies fuel to them, and holds them in place.

Your fuel line should enter one rail near the firewall. The two rails should be connected together by a piece of tubing or fuel line in the front. As the fuel reaches the end of the other fuel rail, near the firwall, there should be a round vacuum canistor with a vauum line attached. That is your regulator. It regulates pressure by controlling the flow of return fuel back to the tank. Pressure is changed by changes in manifold vacuum.

Greetings asmbandit,

Your fuel pressure regulator is built into the fuel metering cover on the 5.0l tbi engine. If you would like, I can send you a picture of it from the GM service manual. [img]graemlins/hurray.gif[/img]

well, i bought a fuel pump and i hope this is what it is...i dont think that the regulators are the problem now because when it finally starts, it runs perfect...my fuel pump is very noisey, and doesnt shut off after 2 seconds... it has a very weird habbit of starting, after cranking it for about 10 secs, the check engine light comes on and it fires right up, then the light goes off....its start exactally like this every time...i just dont get it???
