w injectors,runs real rough . black smoke puring out of tailpipe,within just a few min.see gas guage, going down......sucking gas like crazy. john

See if you can get your money back for the injectors and then go and buy a new fuel pressure regulator. It's pulling fuel past the diaphragm into the vacuum line. If you pull the vacuum line off the reg at the back of the fuel rail and see fuel coming out of the reg you owe me a beer.

pull vac line off fuel pressure regulator and see if its dumping fuel into the intake. then check MAP sensor, possibly by disconnecting it or just swapping it with a known good one.

we put $ 30.00 IN IT LAST NIGHT AND ITS NOT IN THE OIL PAN!!!!!!!!!!!!NO LEAKS just BLACK SMOKE POURING FROM TAILPIPE,USING REAR TANK WITH LOCKING CAP. COULD IT BE ECM??????

I have to call bullshit. There is no way it sucks that much fuel so you can see the gauge moving. There is no way it would even start let alone "run rough".

maybe bad oxyen sensor
