Which one of you ******** has my tuning cable?

 

Check grounds on the head you just replaced. Should be one behind that pink waste gate of yours.

 

That ground is in place by the wastegate, and the other grounds from the body to engine. What are the chances the tune "dumped" when it was parked with no battery for a few months?

 

I don't think the tune would dump, but hooking up your laptop and checking everything would be my first step.

 

Pretty much zero chance of dumping from unhooked battery. The memory the tune gets loaded into is forever. Well, until you change it.

 

I'm in deep , I don't know what to do now.

 

Yeah, might as well try though. By the way, I don't think a missing ground would explain your issue, but it's one of the major things you messed with when taking off the head. What else did you unplug? Check it all. My next guess which makes more sense is an issue in the COPs harness.

edit: just take continuity, then resistance. See if the COP end is continuous to the "igniter" end, and if that's all good check resistance, to see if there's some major damage on one of the connections.

 

sounds like a bad connection, ground short or something...

 

 

Pull all wires and fuse boxes then wire from scratch. Problem solved.

 

This guy.....



What did the tune look like, or did you check it? Any chance you fried something when you hooked everything back up? Getting fuel? Lost crank/ cam sensor calibrations?

 

Ok, aparently pulling the fuel injection relay makes the MS wack out. So when I plug that back in the tach behaves normally, but it still won't start. The plugs are firing reasonably, the keylogger looks good on the CAS signal, and I know I'm getting fuel (backfires, lol). I tried pulling cranking PW from 3.0 to 2.0 after it read 10:1 when cranking, but still no success. It looks like all grounds have continuity so I'm more than a little confused.

 

backfiring out intake or exhaust? Sounds like timing.

 

Its running like it's out of time too. I don't see how it could be though, I just checked mechanical timing and it's spot on.

 

Are your actual cam gears on correctly? Picture with your valve cover off with crank at TDC and the 2 timing marks in the right spot so we can make sure.

 

I fixed it!!!!!!!!!!!!!!! I'm getting pretty good at learning from my own stupidity.
I marked the CAS when I took the car off so I would not have to use the timing light again (shifted balancer). Well, I put two marks on it at 11:00 and 1:00...I did not line these up properly so it was about 30* retarded. Now it runs and damn its strong. The only problem is the rad fan is not working, again. It's never worked properly on this car.

 

I hope I'm not in for this much of a PITA.

 

It won't be a problem if you're smarter than me which is highly likely.

 

lol, 4th gear at 3500rpm on concrete buries the tach on street tires. This car is MUCH faster.

 

Nice, I am glad it is finally working again.
