Gas coming out exhaust

H munster · Nov 7, 2008

Hey guys, need some help here. Wifes car 2000 mazda 626. Complete piece since we have had it. On 4th tranny. Anyhoo engine has always ran great and always stealership serviced. Today its barely running and liquid gas is coming out the exhaust. No more warranty so its on me. Im thinking possibly the pressure regulator??? Any ideas? :icon_confused:

Can't be the FPR, gas goes through the injectors after the FPR.

Got spark at all plugs?

Stuck open injector? If you can, disconnect each injector, one at a time. It should run worse. If disconnecting one makes NO DIFFERENCE in the way it runs, that's your bad cylinder (no spark or stuck injector).

Probably simpler to just pull each spark plug and look at them. One is bound to look different, perhaps wet with gas.

I had a problem with a VW once....I took the fuel rail off and cranked it over so I could SEE each injector's spray pattern onto a piece of cardboard.

Im not with the car right now. Stuck at work. Getting a little more info now that sounds bad. White smoke from exhaust :bawling:

Just looked up a new head $750.00. Anybody know the actual car that this is a clone of? Ford/ Nissan maybe. The engine looks nissan.
