I have a toyota celica gt 1996 with a 97 engine.
What I have done to get it working again.
Changed the alternator , new battery, new fuses, a new starter, new gas pump, fuel filter, oil filter, oil change. The car only starts if I use starter fluid. The lights turn on and the car cranks but it won't turn on. On its own with out the starter fluid.
today i installed the circuit opening relay that I ordered. I listened for sounds like the relay and pump. It all sounded good when I heard them click. I went for the go to see if it turned on. And everything short circuit. There is no power running through the car. I tested the relays in the engine and in the car. All is good. The battery still has 12v. Now I hit a wall where I can't figure out what is wrong.
I know you love the Toyota celica like I do. I was hopeing since you own one. You could help me 8nderstanf my car.
"And everything short circuit. There is no power running though the car"? Have you checked your fusible link?
