Wont start unless manually primed


Turn the ignition key to the ON position without starting the engine

You should hear the fuel pump priming for about a few seconds then shutting itself off.
If not hear replace the engine oil pressure switch
The 3rd wire to that switch is the pumps prime switch lead.
When the engines oil pressure is reached the computer will shut that circuit off and turn on the fuel pump relay
If you hear the pump prime the relay maybe at fault instead

My 1996 camaro rs wont start it ran fine the night before it kicks over starts really weak for a half second then dies


Replace the fuel pump relay
This will work for you
The fuel pumps prime comes from the third wire off the Oil Presure Switch
When oil pressure is achieved the computer shuts off that circuit and turns on the relay for the pump.It takes only a few seconds for the oil pressure to be achieved so that is why your engine dies out almost instantly

Fuel pump not working. Followed your directions to reset theft device. Replaced relay (not sure which one it was...i guessed). Replaced fuel pump. Mother-in-law said she heard a noise from under dash then...


The relay only operates after the engines oil pressure is at operating PSI. If the relay was replaced and the fuel pump is not heard working when the ignition key is switched to the ON position for 5 seconds, replace the engines oil pressure switch. That switches 3rd wire connects to the fuel pump to run it for 5 seconds to prime the engine. That switch can be tested without the engine running. Just turn the key to the on position and listen for the pump to run for 5 seconds

Wont start, checked the fuse, cant seem to locate fuel filter.


Turn the key to the ON position without starting the car
You should hear the fuel pump running for 5 seconds to prime the fuel up to the engine so it can start. If no sound is coming from the fuel tank area which can be heard with the drivers door opened in a quite area the oil sending unit on the engine needs to be looked at. If its bad the fuel pump will not prime. If the oil sending unit is good the fuel pump is at fault instead
Oil pressure to your engine achieves to close the circuit to this switch which the computer senses. When the oil pressure is up to normal standards the PCM shuts that circuit off and turns on the fuel pump relay

Truck wont start easily replaced fuel pump,purge valve,t.p.s,fuel filter.i have to prime 5 times before it will start.


The fuel pump runs off the engines oil sensor switch upon starting. It will shut off when the computer sense the oil pressure is at the normal range and then the computer turns on the power to the fuel punp relay. Change the two and you shall have a running truck again. The reason to replace both is they both wear out in about the same time

Car starts and cuts out after 2 to 3 seconds. fuel


When the ignition switch is turned on the pcm turns on the fuel pump by energizing the fuel pump relay. The PCM keeps the fuel pump on as long as the engine is cranking over or running.It does this by recieving pulses from the ignition module. If there are no referance pulses the PCM will turn the fuel pump relay off in 2 seconds with the ingnition on.

Most models also include a secondary control path through the oil presure switch witch will turn the fuel pump on after it detects oil presure.cranking time will be longer if the fuel pump doesn't recieve current until oil presure switch contact is closed.

1997 Suburban, cranks, won't start. Removed fuel pump and it runs when attached to battery on bench. Power at all fuses, no power on grey wire at 4 prong connector above rear axle. Is there a fuel pump cut...


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

do you hear the fuel pump run a few seconds when you turn the key on? did you check fuel pressure? replaced fuel pump relay? the oil pressure switch may have something to do with this.
