    would i need to change out the cpu, would it have to be reprogram?

  • Anonymous May 02, 2009

    I have the same problem my sunfire won't start either,i replaced the computer and it helped but when i unhooked the computer again i lost all the power to the fuel rail and the spark.If you replace the computer you need to get one with same serial # and same motor.When you put it in you while need to turn your key to the on position (with the battery hooked up) and leave it for ten minutes for the car to relearn the new computer,the anti theft ligth should be flashing while this is happening.After ten minutes the theft light should be solid,then you turn the key to the off position wait a minute and the should start.hope this helps you.

Put on new fuel pump got pressuer but want stay cranked


Your post is lacking any detail. However, if you are stating that the engine starts after being cranked but dies out (wont stay running) there are 2 ways the fuel pump is activated. When the key is first turned on, there is a 5 second fuel pump run (the ECM energizes the fuel pump relay). After the engine starts, the fuel pump relay will only stay energized when the oil pressure switch closes keeping the fuel pump relay on (oil pressure is above 5-7 psi). If the oil pressure switch is faulty or there is no oil pressure, the engine will stall just after starting.

No power to fuel pump on 92 olds silhoutte


The oil pressure sensor only keeps the pump running after the vehicle is started. If you turn key to on, the computer should signal to the fuel pump relay, turning the pump on for a couple of seconds to pressurize the fuel system. Then the computer signal stops. When the key is turned to start-cranking the engine- the computer again energizes the fuel pump relay, keeping the pump running until the engine starts.
If you have a voltmeter or test light, pull the relay out and check the relay terminals. One should be hot at all times-the power feed for the pump. The computer signal will be on the coil side of the relay-will have power for 2 or 3 seconds after key is turned to on. Or it will have a constant signal when the engine is cranking. If you can find both hot terminals at the relay, then start looking for a bad wire from relay to pump, or a bad ground for the pump, or a bad ground for the relay's coil side. Post back if unclear or other questions. When you pull the relay out, the diagram for it will be on the side of the relay-telling you which is the power feed and the terminal to the pump, and the coil side of relay, both the coil power side and the coil ground terminal.

Fuel system wiring 1995 sunfire


Could be ECM/PCM but you need to go further and diagnose it. trace fuel pump wires and find out if there is a fusible link or break/bad connection. If you have another ECM you can try it. is there power at the relay? at the fuse? Ignition module?

2001 gmc sierra 1500 injector fuses and relays


Do you hear the fuel pump running on the prime cycle (when you turn on the key) (runs for 3 seconds) or when you have oil pressure?Have someone listen back by the tank for the wrrrrr.If you do have to change the fuel pump,make your life easy and just tilt up (lift) the pickup box from the drivers side to access the fuel pump.Takes 20 minutes to change it that way.

Ive got a 1997 cavalier it will start but quickly dies out ive got fire to my plugs and fuel to the injectures ive just replaced the ignition switch is there somkind of a security


You need a new fuel pump relay. The engine fires up and runs off the oil pressure switch untill the oil pressure PSI is reached at normal operating conditions. When the oil pressure reaches its operating PSI the PCM or engines computer will shut off that circuit and turns on the fuel pump relay to run the fuel pump untill you shut the engine off

The oil pressure gauge on the engine runs the fuel pump until the engine receives full oil PSI and shuts off. Upon that time the relay takes over for the fuel pump

Low gas pressure in 96 sunfire. Replaced the oxygen sensor, vacuum hose, fuel pump and fuel filter. Fixed the ignition regulator. When I shut off the car it sometimes fires right up right away. It used to...


You have mentioned that you replaced the O2 sensor. The oxygen sensor is completely ignored by the engine computer while the car is starting, and doesn't come into play at all until the engine warms up completely. Are you sure you have a fuel pressure problem? If so, replacing the O2 sensor would not have any affect.

To be sure you have a fuel pressure problem, you need to measure it. This car does not have a fuel pressure test port, so you need an inline fuel pressure test gauge. To test the pressure, connect an in-line gauge and switch your ignition switch to the "run" position. (Do not start the engine.) The fuel pump should run for two seconds. During this time when the engine is not running, you should have between 41 and 47 PSI of fuel pressure. If you start the engine, the fuel pressure should drop somewhat at idle (maybe somewhere closer to 28-35 PSI). Fuel pressure is regulated according to intake manifold vacuum, so at idle, it should be fairly low, while at higher throttle settings, it should be higher.

From what I gather, your car cranks for a long time before starting. If you suspect low fuel pressure, a defective fuel pump relay could cause that condition. The relay is located in a relay/fuse box under the hood on the driver's side of the car. If the relay fails, the fuel pump can still be energized by the engine oil pressure switch. This switch closes when engine oil pressure reaches ~4PSI. If your engine is not producing 4PSI of oil pressure while cranking, or if it takes a while to reach 4PSI, that would explain your problem.

1997 pontiac grand prix with major issues


check all fuses for turn signal and brake lights.change fuel filter . first. do a little tune up change spark plugs and wires . if changing fuel filter dont help. have fuel pressure check first before buying a new fuel pump .they run after taxes 400.00 dollars. your fuel pressure should be 41 to 47 psi. replace fuel pump relay also.
