I have an 1987 Toyopta Supra Turbo and I had my gas tank repaired and the place that repaired it wired the fuel pump wrong. It blew the EFI fuse. For several reasons I ended up replacing the fuel pump and now the car wont start. I checked the fuel system and pump is working and getting good pressure. I did find out that the 5 & 6 spark plugs are the only ones firing. Did the resistance test from the shop manual and all coils checked out ok. Was thinking it might be the igniter but a tech at a local shop said none of the plugs would be firing if the igniter is bad. I'm kind of stuck. Hope someone out there has some good advice for me.
