Okay. Jumped the pump and tried cranking it but its the same problem, doesn't stay on.
changed-out the map & iac, checked the relays, and fuses, the timing and nothing. the pump is working. I loosened the fuel fitting on the cylinder head, on left side and fuel gushes out. besides, this pump came from my other running Camry.
so now I think its the injectors. I'm all out of ideas. something is cutting out after the initial firing of the engine. pretty certain it is still fuel since pouring gas in the throttle assembly helps it run a couple seconds longer. what sensors can cut out the injectors? do the main engine modules reset
themselves?

 

i have a 92 camry.. it studdards whle in park or when i come to a light but not while driving.. can anyone help me???

 

Im having the same problem with my Camry. Did you fix your car?

 

Check the intake air control (IAC) valve and for vacuum leaks.

 

Have you tested the injector wires? I don't know the values for your year, but you should be able to pull them up, and test with a voltmeter what each wire is sending to the injector.

 

I've got a 96' toyoa camry thats refusing to crank up and start I've checked all fuses i changed the coil because the was no spark but After still nothing i tested the fuel pump manually 12v it works fine put it back in its plug no fuel pressure i changed the EFI still no fuel what could it be, i went to a electrician and explained it might be the ''ckp sensor '' might be dirty and wont send any signal to ecu to read for fuel, but Still i want to know when key is on doesnt the pump should kick in and send fuel immediately or does the fuel pump work through the ecu plz plz help.

 

The engine needs to be cranking over or running for the pump to run.
