[QUOTE="SlipperySnake, post: 15565107, member: 132229"] Haven't been on here in a while so hopefully posting in the right section. I have a twin turbo 04 cobra and the other day got to the big moment of starting the car yet to find out that all it does is turn over. After diagnosing I came to conclusions that the injectors and ignition coil plugs are getting no pulse. I did extend the wires on the injectors and ignition coils for a wire tuck, all connections were soldered and heat shrunk and they were wired correctly two wires at a time, I know I didn't miswire anything. The coils and injectors have 12v on the hot wire with key on, no pulse with motor cranking over on both. I tested the camshaft posisitioning sensor and ground on the plug to it. I haven't tested the crank sensor yet and am going to this evening, but the pcm is displaying RPM during cranking on my aeroforce gauge. Block is grounded, I've gone over and made sure all plugs are good to go and I can't find anything that isn't grounded. I don't have the alternator installed but I've heard and am almost positive that wouldn't affect this. Anything I'm missing that y'all may need let me know. I've come to think it may be the CCRM, bad PCM, bad crank sensor(that picks up rpm) or something I am missing somewhere. Car has been down 3 years and ran fine before but a lot has changed. Any help is greatly appreciated, thank you in advanced guys! I want get this damn thing running!!!! [/QUOTE]
