How To Test fuel pressure regulator I own a 2000 Pontiac Grand AM SE 4 cylinder two door. I have sparodic but continuing problems with my car not starting up after i have made mutliple stops shopping. When it does not turn over, I leave it for a half an hour and come back and it starts up. I have noticed that when I pop the hood and check the oil guage the engine is very hot. It seems when it cools down it starts. I have been told this problem is perhaps related to an oil sensor or perhaps oil pressure. The "Change Oil" indicator on the panel is always on, even after I have the oil changed. You should check the fuel pressure regulator at the end of the fuel rail. There is a vacuum hose on it. Pull the vacuum hose off and check for raw fuel inside it. If there is raw fuel, replace the regulator. You might need to test this several times, or when the vehicle will not start.  what can happen is the regulator will leak fuel into the cylinders flooding the engine...

Pontiac Firebird: Fuel gauge and oil pressure. What would cause the fuel gauge and oil pressure gauge to peg and stick at the top. Where is the oil pressure sending sensor located Pontiac Firebird? The oil sending unit is located at the oil filter boss on the engine block. I will attach an image to make it easy to locate. When the oil and fuel gauge stopped working,did they both go out at the same time? not at the same time. oil gauge went first and then there was quite a period of time before the gas gauge did it. The fuel gauge *may* have lost is ground or it is corroded. I can supply you with the ground location if you would like? the gauge works on resistance,at 0 ohms it reads empty at 90 ohms it would read full. with an open circuit or a bad ground it would of course peg it up above full. if you find that the ground is good most likely the fuel sending unit has failed. On the oil gauge,it isn't uncommon when pulling the o...
