where & how to reset my 1990 4-Runner ECU?

[ronnie_g]

My 4-Runner broke down after driving it for about 30 min. It accepted charge by jumping it but the engine runs for less than 2 min. and it dies.
It had to be towed to my house because I wanted to find the problem myself before I get rip-off. The battery is 2 months old so I know it can't be it. But, with the help of my charger to start the car, it stayed on for about 2 minutes again and shuts off. Well I did some trouble shooting to see if it s the starter. With my luck, I found out the wiring connector from the starter was crummy and wiggle the wire twice..., then it broke! I tried loosening the nut that holds the wire, but the bolt itself that attached to the alternator broke! Luckily again, there was another nut that hold the ceramic or plastic shield that covers the bolt. I was able to loosen it slightly just enough to insert my improvised spade-tongue terminal connector. I think I solve the problem for now as long as the bolt does not come off.

My problem right now is to find out why my check engine light went on??? Please help me out to find the location of the ECU and let me know how to reset it. If any of you know the codes of engine or any related problem for 1990 4-runner auto..., please post it here or email me at [email protected]

Thanks folks

About half of the ECU codes stored on the first & second generation EFI Toyotas don't show a constant blinking check engine light therefore you must pull the ECU codes to see if a fault is registered.
To pull the ECU codes:

All 1980-1995 and including 1995 EFI equipped vehicle allow you to find engine and related faults by pulling the ECU (computer) codes without the need for a handheld OBDII diagnosis scanner,the sites listed below have the fault codes needed to pull the codes and the instructions on how to do it:

To reset ECU simply disconnect the battery or the 15 amp fuse found in the fuse box next to the dianostic box on passenger side fender for 1 minute or so.
