So a month after installing my JBA long tubes in the 06 GTand installing a new diablo tune I still can't get the vehicle to turn over.
I have a theory it might not be getting spark but I am unsure of what might prevent a spark getting to the Plugs.
With advaice from diablo I went out and bought a set of “noids”. I did both the COP’s and Injectors. I got some light out of the injectors but non on the COP’s. So what might cause no power getting to the COPs’?[/align]

i believe the voltage to the C.O.P's all
come from the same fuse, in the engine
bay fuse box. the grounds to the C.O.P's
are controlled individually by the PCM.

I'll see if I can find you the fuse #

I checked all the fuses already, its a 20AA small fuse. Didn't seem to have any burned fuses.

Have you actually checked to see if you have spark for sure or not? The reason I ask is because on my 2005 GT I had similar troubles. My car would turn over but wouldn't start. At first we did not think we were getting spark but after pulling one of the plugs we found that the car was indeed getting spark. We eventually found out that the car was flooded. We removed all the spark plugs and the cylinders were full of fuel. So basically the fuel was drowning the plugs.We ended up blowing them out with some air and then putting in new plugs. It started right up after that. As for how it got flooded, I have no idea. I bought the car that way. I purchased it from a auto repairable dealer hence it had some front end damage.

Now if your car doesn't turn over at all I would say to look into your starter and check your grounds.

Thecamshaft position sensor is the first component to trigger a COP firing (I believe). It sends the cam position info to the computer which will then tell the correct COP to fire.

If an engine stalls out then the cam sensor will tell the computer and it will stop giving any firing orders to any of the COPs.

So, I guess.... if you had a bad or dead cam position sensor then the computer wouldn't receive any info needed to send firing orders to COPs, and the computer would treat it no different than it would treat a stalled car.

Well the Noid lights validate if power is getting to the plugs,and I as I statedI never saw anything.Though I will look into your statements and pull a few plugs to see if the cylinders are flooded.

I've pulled and reattached the cam sensors several times.
I don't seem to be getting any errors from the diablo programmer either.

Do you have any DTCs stored?
Can the Diablo check DTCs?

hammeron

good point.

also, i believe fuse #40 is the
one we are interested in.

I realize you say you've re-seated the CPsensor several times, but what if its bad all together? Also.... When you try to turn the car on, is the CEL light on or does it go out after its initial check?

I think The plugs are the issues. Heres 3 that were pulled. They all looked f'd up. These have about 2000 miles on them.
