Toyota Repair: Camry stall, coolant temp, pvc valves

Question
I have 1996 camry 2.2 5S-FE engine.  It stalls after 3-4 minutes of cold starts.  restarts after waiting 1 minute.  Works fine then.

I have changed IAC, thermostat, plugs and wires, Intake temp sensor, coolant temp sensor, TB cleaned and all cooling fan relays in engine area.  Mech check fuel system, the pvc valves and distributor - everything ok.  No diagnotic errors except when too much heavy cranking, i get code 13.

please help!!!!

Answer
Ive seen a few things that lead to extended crank, and stall.
The EFI main relay- If thats the case youll have no check engine light on the dash when it doesnt start. Thats because there is no voltage to the ECU.

I also have seen a bad pickup in the distibutor. They usually cut out when hot, but have seen them cut out as you described on occasion. No way to really check. They test fine, you need to swap one to check it.

Ive seen a bad O2 sensor do that also, but usually get a code in the ECU for it.

Also dont look past something in the fuel.
Take a fuel sample.see if its got water or dirt etc in it.

Let me know how you make out.
