92 V6 has Spark but no Fuel

[steve_K]

Hello,
I was wondering If someone could help me. I have a 92 V6 camry with 187xxx miles that has spark but is not getting fuel. I don't think its a timing belt Issue because the car was idling in the drive one week and the next week it would not start plus it is getting fire to the plugs.
My first thought was fuel pump but I didn't want to buy one till I was sure it was the problem. However I don't have a tool to test the psi of the pump but thought I could test the leads to the pump for voltage. well there are five leads and I can't distinguish which leads are which. I assume it is the larger diameter two of the five. which there is no reading. In addition there is no cycle noise or noise comming from the pump.
Next I examined all EFI fuses physically and with a ohm meter for shorts...no problem, After that I pulled the EFI Relay (with the Ignition on) and could hear a clicking noise along with another relay clicking somewhere in the engine compartment. last I tried to test for injector pulse with a noid light conected to the ends fo the injector harness but the light would not flash. However I could get a closed circuit if I grounded the noid light to the engine (which was dim) or to the neg post of the battery which was brighter. Did I check for Injector pulse correctly? Any great sugestions Are apreciated.

this is just a shot in the dark, but is your gas cap securely tight? does the gasket on the cap need to be replaced? im just guessing that theres a lack of pressure? then again youre getting a spark... idk?

^ quite the long shot indeed the fuel pumps pump into the fuel lines, they dont pressurize the tank. It will run with no gas cap just fine.

Steve, you had the right idea with the noid light and the injectors. The fact that they have power tells us the ecu has power, its just not firing the injectors for some reason. You should probably start with the air flow meter, which will also allow you to check the fuel pump. Take your intake filter out and reach into the afm, open the afm flap with the ignition turned to on and you should head the fuel pump kick on.

Where in NC are you located?

if you turn the key on and dont hear he fuel pump kick on then star with the wires at the pump and work your way back to the computer check the wires for kinks melts corostion also will cause a no start even scotch tape on one of the posts on the battery will cause a no start. so start simple
