, STALLING RIGHT AFTER STARTING UP, NO SECURITY LIGHT

2000 Toyota Corolla • 170,000 miles

Having a stalling problem on a 00 corolla. I have checked condition out and confirmed that the fuel injectors are cutting out after the first few seconds. I don't see any security lights. How do I further diagnose?

It's not a security problem. The headlights and horn would be flashing if it was. You could have a shorted injector. I would disconnect all of them, and see if you can keep it running with carb cleaner while monitoring a noid light on the injector plug.

Ok I will check it out with noid light.

Question: would the computer shut down ground pulse to all injectors if it sensed more draw/short on any given injector?

I will check coil resistance on all injectors and compare.

With all injectors unplugged I cranked the engine, and the ground pulse was only there for 2 seconds. After that there was no activity.

Could be a bad computer but all the wiring has to be tested first.

I agree, Where should we start?
Should I test cam sensor circuits first, or what would you recommend.
Wiring diagrams go a long way and really help. Thanks

Can you also get me a wiring diagram for ignition coil (COP) #4, there are four wires on it, 2000 corolla 2.8l

2.8liter or 1.8 liter? Our reference shows only a 1.8 liter engine. Manual or automatic?

I meant to say 1.8l, and it is a manual drivetrain.
I need to check wiring on the #4 coil, It got four wires going to it. Thanks

Is there any thing with the coil circuits that would keep the injectors from firing.

Trying to get the injectors firing again.

Injector fire for the first 2-3 seconds then shut off.

That sounds like an ASD, automatic shutdown relay.
