I new to this forum and have a problem with my 91 truck with the 3.0 v6. There is no spark. I've tried a different distributer, coil, igniter, and ecu from my parts truck and still no spark. The coil and distributer test ok and i've tried 3 different igniters. I have searched old threads and can't think of anything else.

 

checked your fuses?

 

I tested the fuses and they were all good.

 

Gotta be the wiring in between all that stuff.Did you check to see if the injectors are getting their signal?

is the coil wired up properly?

 

Coil is wired up properly. The only thing I can thing caused this is when I welded together a battery tray. Also around this time I replaced the positive terminal because the old was trashed. I looked don't see where any wires were damaged. Maybe I should go make friends with a Toyota tech
