so i have a 7mgte supra and it was running fine but then the battery had died. and my friend put the jumper cables on backwards. so now all it does is crank but its not getting any spark, so idk what the problem is. i tried changing the ecu and doesnt make a difference. any other idead? maybe the coil pack blew? idk can anyone help me?

 

could have fried the igniter.

 

thanks any idea on how to check if it still works without getting a new one?

thanks alot much appreciated!

 

Did you check all the fuses? What have you tried so far as diagnosis goes?

 

checked all the fuses there good swapped the ecu . and checked the coil packs with a light tester and no light came from them so i guess the coil packs are fried.

 

a light tester? you mean a voltage tester? and no, that would not mean they are fried. that would mean they are not getting voltage, or if you mean tested them for spark, that means they arnt being triggered. they are triggered by the igniter, which is triggered by the ecu. go to the link i posted and test your igniter. sounds like the igniter is fried, not the coils.

 

i gotta get the tools to test it first. but thanks for the help bro.

 

If you end up needing an Ignitor, I have two extras. You can have one for twenty bucks.
