Okay, ever since I have gone turbo my car has not run properly. At first the ride was rough, and sputtery. The latest turn of event's ever since my car died while test driving it is that my car will not start. I have tried everything, and nothing seems to work.
I have replaced the following:
CamPosition sensor
CrankPosition sensor
Coil Pack
ECM
I have checked all of the wiring, and I just simply cannot figure out why the hell my car will not start. I have fuel pressure, but no spark. For some reason the ECM is not sending the signal to fire. I don't know what else to check. I have checked that manuals and as far as I can tell I have replaced everything in the path that the car checks before it sends the spark signal.
Please please help. I am about to take this thing to the dealer and let them figure it out, but god knows that I don't feel like paying them what they are going to ask.
Also, which port on the FMU's are the in and the out? I belive that the one on the bottom goes to the tank, but my fuel rail does not hold pressure on it, I wasn't sure if that was how those things are suppost to work or not. Anyhow please help!

Have you tested out the ASD relay? Are you getting signal at the coil pack connector? At the ECU (for the same line)?

Please elaborate on the ASD relay.

Were is it, and what was the other thing you mentioned about the ECM? I know that there is no signal at the coil pack. More than likely this is the problem, I have not messed with any relays other than the fuel pump, and whatever the other one is by the driver side on the fire wall.
I think we might be on to something here. Please respond soon! Thanks

Thats it.

If you don't have poweer there there might be a problem with the ecu.

What about the fuel question. Does that sound normal?

Simple, stupid question.... Have you checked the battery yet?

Have you verified voltage TO and from the sensors? The yellow wire for CrPS and CmPS should give you 8V (the black/green wire is ground). If your sensors arent getting power to them then its an ecu or short problem. You can verify the power very close to the ecu on the bottom plug, thick yellow wire. Then verify your getting voltage back to the ecu from these sensors (blue/white wire on CrPS and blue/red wire on CmPS).

turns out the speed sensor was grounded. This drew down the 9v constant voltage on the other sensors so they wouldn't read right.

All of my problems were due to a faulty speed sensor. I recommend that if anyone has a starting issue from now on, unplug each sensor one by one.
