car wont start??

[ill cuhz]

Agreed. My personal plan of attack for this would be:
Check batt. Voltage
Remove both batt. Terminals and clean them very well.
Trace negative from batt to body. Remove and clean.
Trace negative from body to block. Remove and clean.
Trace positive from batt to starter. Remove and clean.
Trace positive from batt to fuse block underhood. Verify the fusible link and the alt fuse are intact and no corrosion on connections.
Check/clean ground connection at intake manifold.

After all that, try to start it. A load test on the batt is a great idea too, if you have the tester. May also, for good measure, put the batt on a trickle charger while cleaning and inspecting you'd wires.

I've had this exact same issue and solved it by replacing the connection from the batt + to the fuse box.

judging by diagram joining yellow and white should put it in neutral perma.

That's supposed to happen.

Have you checked voltage and/or resistance on any part of the starting circuit yet??

:nono:

I think we should proceed directly to the starter relay mod! This diagnosis stuff is overrated! :icon_sad:

Believe me

No thanks.

Uh? You can disconnect that while the car is running and she will keep running..

Don't ever do that. You could end up on ebay after Toyota tells you how much they want for a PCM. Do you know how magnetism is related to the alternator? And what happens when the field collapses?

4 any ideas??

Discharged battery or excessive voltage drop in the circuit.

Don't ever disconnect the water temp sensor gauge while the car is running?

Looks like I got my wires crossed as well. I think that is enough Scotch for a while.

^ I was wondering. And lmao @ 3p. It's so true...

It is five oclock somewhere.
