she just doesnt wanna fire, i have power to the coil, all leads are on, fuel pump is working. after turning over i noticed the motor will run backwards for a sec, is this a sign its the crank angle sensor?
ive spend days nobbing about, she`s such a good girl normally.

It does sound like the CAS. I think running water over it can help.

Does it have spark at the plugs? Fuel flow and pressure? Compression

cheers, i been looking for it! it has power to the coil, i admit she does seem to be spinning over quicker than normal. i shall short the ecu and see if any codes come up. i sprayed aero-start down throttle body to see if she`d fire to tell me if its fuel and no sign of life. cheers.

The ignition module is the most likely thing to break with the 5 liter

did you wait for the code to be repeated 3 times? I made that mistake, code 12 repeated 3 times then I just turned the ignition off. Every code is repeated 3 times so wait till after code 12 comes up 3 times, then check for a different error code.

Igniter will be your problem most likely if you have no spark. Silver thing on the left hand guard from memory.
