    Fuel pump, I have changed everything to do with the ignition, I'm getting fuel just no spark I don't know what else to do even got a new computer still nothing. It wants to start it kind of backfires

    My reference material is vague about location, but if you go to the center junction box and trace the BLU/ORG lead A3, you'll find it. BLU/ORG lead A2 goes to the fuel pump

SOURCE: no power to fuel pump. I have power up to the circuit opening relay.

I am not positive how the electronics are routed on a later model truck but I had this same problem on my 89' with a 22re. It turned out that the oil pressure sending unit was in the fuel pump circuit so as to not allow the engine to start with no oil pressure. I changed my sending unit and the truck fired right off. Hope this helps.

SOURCE: 1992 4Runner circuit opener relay causing rich Idle

It may be that the O2 sensor is faulty or contaminated. Another possibility is that after running rich for some time, the catalytic converter is slagged and no longer working properly. Have you been able to get any diagnostic codes from the car's computer? Is the check engine light on?

Start by checking the ETCS fuse in the engine room fuse box. If it's good, you may have an open circuit between the fuse box and ECM.

More then likely you have a bad ground wire. You will have to start tracing this problem back to find the issue. Other issue is a intermittent power wire shorting
