My brothers vp ss 5.0l stopped yesterday, he had a play with a few things in dizzy etc. I got involved and tested for fault codes, code 12 comes up which is the (no malfunction code) its still got spark, (its not the best spark but its still blue in colour) ive tried another coil but no change. injectors are pulsing and fuel is entering cylinders, fuel pressure is 2.5-3 bar. firing order is 12784563, new cap rotor and leads. compression tested all cylinders, 130-140 psi. new platnum spark plugs. ive connected my scope to the ignition module and there is a 5 volt signal that comes from the engine ecu and ive overlayed this signal with the coil primary signal and both match. so ive got fuel, spark and compression but this thing still wont start. ive had the engine at tdc#1 and the rotor is pointing at about 2oclock sorry for long spiel but any help is appreciated. thanks guys.

Borrow an ignition trigger, the one that sits on the guard or swap the dizzy, it has a CAS inside it that can fail.
