Troubleshoot nightmare. Out of options. Please Help!

**BlackGTP01** · 01-28-2015

So I recently purchased this 01 GTP with 100k on it. Love the car, ran great for a month. One day a block away from the house the car died. Been working on it quite some time now.
Just recently did the Gen V swap. The original rotor pack locked up. So long story short, the car has no spark. It turns over but will not fire.

So here is what I've already replaced new:
Gen V Blower w/TB adapter (Followed Sticky from Forum)
Crank position Sensor
Iridium Plugs
Fuel Filter
AC Delco Ignition Switch
ICM
MSD Coil Pack

I've also pulled the alternator + starter and had them both tested - Good
Checked every fuse, all good.

I've exhausted all options. Had friends help me with it too. All I can think of is chasing all my grounds next.
What about Camshaft position sensor?

Hopefully someone can give me any kind of advice. Car has been down for over 5 weeks now. I bought it 2 months ago. Drove it 4 weeks and now this.
Any input is appreciated. Thanks

Bump for help please!!

Does the engine turn over or is there absolutely no power

**Sven the Sexman** · 01-30-2015

Have you checked fuses....?

**Below Average Joe** · 01-30-2015

fuel pump, FPR?

**Below Average Joe** · 01-30-2015

it says he did.

**Sven the Sexman** · 01-30-2015

Well it says he's missing spark...new lots of things...I missed the fuse part...my bad. But, there's not a lot to getting spark on the car other than CKP, ICM, PCM, and proper powers and grounds. Have you tried swapping out the CKP harness?

**BillBoost37** · 01-30-2015

I suggested bent pins on ICM or the connector right at the FPR.

The truth is..you know Mitch....hence he's the issue.

**OneEyedGuy** · 01-30-2015

Get rid of the MSD's and get some OEM coil packs on that puppy

**BlackGTP01** · 01-30-2015

I'll start checking for bent pins and follow all my grounds. The car will turn over but will not fire.
I purchased a HEI spark tester to verify it has no power. I just ordered a new AC Delco CPS so maybe that will help from aftermarket.
The only positive out of this is I'm learning a lot about the car so future problems shouldn't be hard to fix!

Thanks for the input, I appreciate it, I will post updates.

Why a CPS? Shotgunning parts at a problem is an expensive way to fix it.

Did this issue appear before the Gen V swap? You say there's no spark, at the plug? Backtrack from there... Coils, then icm... I'd definitely ditch the MSD coils as they offer no benefit over stock.

Yeah I agree, I'm already into a grand in new parts still with no progress. One night driving home the car died and would not start. After troubleshooting I found the S/C rotor was locked up. So the car turns over but will not fire.
There is no spark at the plug. Sounds like the MSD coils are useless so i'll return the new one I just put on. I just put in a new ICM.
Right now I'm currently waiting for my new AC Delco Crank sensor switch in the mail. I have a feeling the aftermarket one I put in from Kragen might be junk.
Haven't tried working on it because I'm waiting on that for now....very irritating. Thanks for the advice, its is greatly appreciated.

**BlackGTP01** · 02-07-2015

so I finally got the car running. I replaced the aftermarket crank position sensor with an ACDelco one, and redid the ground to the ICM.
I miss one nipple off the throttle body next to the 3 plugs, does this just get plugged off, when you do the gen 5 swap?

The thing that scares me is the car smokes a little bit at first. The last time the car was running I ran seafoam threw it.

the last thing is the car is throwing engine codes now too, is this normal because the car has to be tuned? After the gen 5 swap?

Thanks for the help!

**ADrugDealer** · 02-08-2015

what are the codes? If you just got done working on it its going to smoke some. spilt fluids like to smoke lol

**Scottydoggs** · 02-08-2015

did you run the pvc line from the blower to the tb? like this? http://www.grandprixforums.net/threa...cover-breather!

that other open hole on the blower is the evap port. you need to seal that off because your not using it.

and post some pics of your set up, this way we can tell for sure its all right or not.

**BlackGTP01** · 02-08-2015

It was a vacuum line. Newbie mistake.

is photobucket the only way to post pictures on here?

**BlackGTP01** · 02-22-2015

So this car is still giving me trouble.
Somehow there is coolant dripping out of my TB adapter.
How is this possible, how would coolant be coming through the S/C?
Somehow I still have a misfire on cylinder 4 too.

This is a joke the amount of time and money I've spent to still be having issues.

Any input is appreciated.
Thanks.

**Scottydoggs** · 02-22-2015

coolant does flow to the tb. so take off the tb and spacer and rtv it all together.

**BillBoost37** · 02-23-2015

It's kinda funny you have coolant leaking there. When I first met Mitchman... I was giving him advice on coolant going down the intake.

**BlackGTP01** · 03-08-2015

Thanks for the input. Long story short. The broken spark plug I found melted a piston. Which explains cylinder 4 misfire. So now I'm tearing into the motor. Again.
Sorry for the delayed responses. Been really busy. I have to make a photobucket so I can upload pictures.
Needless to say, I'm not happy. I've had nothing but problems with this car. Just hoping to catch a break for once.
You know how that goes.
