Where is the fuel tank pressure sensor 0n a 2000 cavalier


I have never heard of a Fuel tank pressure sensor.. The fuel pressure comes from the Fuel pump which is in the fuel tank.. The pressure is regulated (Fuel Pressure Regulator) on the fuel rail on the engine near the fuel injector/s. The code PO254 is a generic code.. could mean different things.. Does it seem to be impacting how the car is running?

Why my 97' f-250 7.3 powerr stroke keeps dieing while idling


The power stroke engine has several things that will cause this problem #1 crank shaft sensor AKA cam shaft sensor on crank shaft located on passenger side of engine near crank shaft pulley # 2 IPC sensor Injection pressure control if has oil in sensor replace it & wiring pigtail .#3 high pressure oil pump not up to par. #4 injection pressure regulator solenoid they get sticky. with a good scanner that has FORD enhanced software you can check all of these without leaving the drivers seat and perform running tests on injectors and test the ficm module interface with the pcm. Fuel Injection Control Module & Power Control Module.

Change the fuel pump and still won't start on a 2002 chevy avalanche


Check for spark to the spark plugs, while cranking the engine. If no spark, you could have a bad ignition module, or a bad crankshaft position sensor. The crank sensor sends a signal to the computer, to start the fuel pump and signals the ignition module to start firing the spark plugs. It also drives the tachometer through the computer (PCM) Powertrain control module. The ignition module can be removed and taken to a parts store to have it tested. The crank position sensor is not as easy to test. Easier to just replace it. Good Luck. But wait, I have seen people replace the fuel pump, checked the fuel pump harness for power, and all was good. However, if the fuel pump does not have a GROUND, it will still not operate. Might want to check that. Have fun.

BAD FUEL PUMP CHECK FOR FUEL PRESSURE WHEN ENGINE DIES AGAIN,IF YOU GET ZERO FUEL PRESSURE FUEL PUMP COULD BE BAD, I WOULD REPLACE FUEL PUMP RELAY FIRST BEFORE BUYING NEW FUEL PUMP.IF FUEL OKAY YOU COULD HAVE CLOGGED FUEL INJECTORS OR WATER IN FUEL, FUEL COULD BE CONTAMINATED. I HAVE SEEN A FAULTY ENGINE COOLANT TEMPERATURE SENSOR CAUSE ENGINE TO STALL OUT.

I have replaced the fuel pump on my 1994 pontiac grand prix with the 3.1 litre v6. But it does not seem to be sending the fuel to the motor? In the instructions it says something about the oil pressure...


Are you sure that the fuel pump is properly installed? Have you tested the fuel pump circuits to see if they are working properly? Did you also replace your fuel filter? (It could be totally clogged up) Have you checked to see if there is any fuel pressure at the fuel rail or are you just assuming that the pump is not delivering fuel to the injectors? Have you checked your fuel injector circuits for power and for injector pulse from the EngineControl Module? Have you scanned your Engine Control module to see if you possibly have a Crank Sensor or Cam Sensor problem?

The oil pressure switch only keeps the fuel pump running once the engine starts. The fuel pump should run for 2-3 seconds when you turn the ignition switch to the "Run" position to prime the injectors. The oil pressure switch is the problem only if the engine will not continue to run on its own after it starts up.

1. Freeze Powertrain Control Module (PCM) and see if the problem can be duplicated.

2. Wiggle tug test wiring for #2 injector.

3. Scope the #2 injector for a glitch when the misfire happens. 1. Test for the Exhaust Gas Recirculation (EGR)/coolant adapter gasket leaking EGR gases past the gasket.

2. Connect a vacuum pump to the MAP sensor, block the vacuum source, reset fuel trims, start the engine and add typical vacuum to the MAP sensor and check operation.

3. Test the spark output with 2 High Energy Ignition (HEI) testers, at 25 KV air gap each, at the spark plug wires to ground at wires 2 and 3, then 1 and 4 at cranking speed and engine running.

4. Test the fuel injector pulse width at the injectors compared to the scanner data.

5. Disconnect the O2 sensor, reset the fuel trims, test the system operation in open loop, test injector pulse width. Compare to the closed loop operation injector pulse width and engine operation.

6. Test the Powertrain Control Module (PCM) powers and grounds during the problem.

Tahoe 97 Fuel problems


Crank sensor has to be bad,or the ignition module.Remove the ignition module and have it checked at the parts store.If it checks bad,replace it,if it checks good replace the cranksensor.The cam sensor,cranksesor,and the control module control injector pulse,and coil spark.I would point more to the ignition module.But I have known the crankshaft sensor to do this also.I hope this was helpful,if so,let us know,thanks,and good luck.

Car turns over but wont start


you need to get your hands onto a diagnostics/scanner computer to check for cam and crank sensor problems. i believe if i am not mistaken loss of crank position signal will kill injector pulse. look for this signal with the scanner if nothing comes up then u have a bad sensor
