Hey guys I'm having a problem with my 87 turbo 2 its only firing on 3 ports T1 has no spark. I changed the whole trailing coil assembly with a new one(used) but it has the same problem. I'm running a haltek e6k and msd 6a

 

check your wiring and EMS, the trailing has 2 individual circuits that control those coils.

 

so I checked the esm and when I check the br/y wire it stays at 2.4 volts with the engine off and key on. when I turn the crank by hand it doesn't change. my car has a haltech ecu in it and I think the wrong wire might be going to the br/y wire from the haltech or maybe the main relay is no good?

 

Well no offense but if your car has a Haltech I would post in the Haltech section about this problem.
This section is like a General section basically for stock Fc's ..more or less.
You get out of the scope of Stock when you toss in an after market EMS that requires finesse..
It's bad enough that the average guy can't understand the stock system..
