I was given a 90 Celica GT, the guy who gave it to me reversed the jumper cables when he jump started the car it blew the 100 amp fuse, what other damage could that have caused. It now has no spark or fuel, how can I check to see if the ECU damaged ? It also has a toyota alarm ,will that cause a no spark or fuel situation ? Thanks KTS

I wish I could help you, but I have no experience with anyone trying to jump start a car with the jumper cables cross connected. If you blew the largest fuse in the car, I would think a lot of the smaller ones would have blown as well. Who knows what condition all your relays are are, and electric motors. You would almost have to go through everything, piece by piece, to sort out what works and what doesn't, and then find where the fuses and relays are for the items that don't work.
