Trailing coil does not fire?
 

The goods.

Swapping coil does not change anything.
The coil is getting 12v.


what would stop it from firing. The haltech looks correct.

It worked one day and the next it stopped?
Thanks,
Ian

This is a long shot, but it might be worth a shot...

If possible, unplug the fuel injectors and ignition output (i.e. coils) from the Haltech harness.

Reset all the Haltech settings, especially the ignition ones.
I like to reset the Main Set-up page from ADVANCED to BASIC and then back to ADVANCED.
In Ignition Set-up, cycle through the Igntion Type from DISTRIBUTOR to DIRECT FIRE and back.
Also don't forget to go into the INPUT/OUTPUT set-up and cycle the AUX OUT away from TOGGLE and back.

What firmware are you running?
Are you running v6.34?

V6.34

Compaq software from haltech.

What do you mean by reseting? How do I reset? I have reloaded the maps twice to see if something would change and used different maps.

I will try as you suggest but it will not be for few days.

Do I change those settings with it disconnected from the haltech or connected?

Change it from the proper settings to something else.

KOKO - key off, key on

Change them back to proper settings.

KOKO

Check to see if that worked?
