corolla 91 automatic, full injector.
when I want to start the car from the ignition switch the cars turn on but when i released the key it turn back off. if i leave the key on the car stays on but the starter is also running.
Ive check all relays(2) computer,fuses. got da same model so I be swapping parts to test them.
sometimes it starts normally but its rare.
on the transmition nautral there are 4 cables, the 2 red one are for the reverse lights, the other 2 black ones are the one that starts the car.
I unplugged the cable that goes to the starter, then I plug a positivr cable direct to the battery to one of the black cable of the nautral safety switch plug, then I plug a external posive cable straight to the starter and guess what, the car starts fine
but once I unplugged the positive from the NSW plug the cars dies but again some time I unplugged it and it stays on.
the thing is that I want it to work like before.
