Rb25Det - Unusal Missfire...

[duluck]

Hey,

I have a R32 with a RB25DET which is running a Haltech ecu.

Car has been running perfect for months have had no issues untill today..

I drove the car into the garage running perfect to install some coilovers.

after the install went to start the car up wouldnt start at all.. then pulled a coil off to check spark

it had no spark while cranking and a very quick weak spark once i stopped cranking it. so it would start but run

very rough and wont rev over 4grand. (up to 4k is very rough) have noticed the two green relays are rapidly clicking

while running. please help...

Also car has brand new yellow jacket coils and new plugs and no AFM as it has the haltech.

Maybe try another set of coils or coilpack loom?

The fact that it wasn't sparking during cranking sounds like the problem right there..
