im getting no spark at for my bosch coils, i have it wired it up as the neg as signal to the ecu and the positive to the battery. im getting no spark, i have no errors according to the ecu hooked up to the laptop and im getting fuel. the only thing wrong is that there's no spark, i dont know why, i need some help, i been troubleshooting for 2-3 weeks now. someone give me some ideas. i bought this ltx8 used.

Have you checked the crank angle sensor to make sure it's hooked up right? What about the settings setup for neg trig, make sure it's not set as something else.

 

yea i checked the wiring on the cas many times, i even go a new plug and rewired it, im going to take out the cas and find out. which setting is setup for neg trig?

I had to go look....
on screen 31 make sure the following is set:
Input Trig + POS
Spark Trig - NEG

 

still not working, any other advice

thanks
eric
