on the freeway..
pretty much shut off completely and I was able to swerve to the shoulder and park. WTF. My battery was reading at 12v. and I didn't get an oil pressure reading. I have APS TT+unichip. Lights come on, but the Car won't start.

 

sorry bro...

 

sucks man??? any tapping? oil pressure. Hope your not blown. cause thats 8k maybe more? for built motor.

 

he aleady has a built motor. Maybe limp mode or something with the unichip?

 

Were you just crusing or were you on the car when it shut off? On my APS single turbo if i am on it then let the revs fall fast the car will stall. But that was when i miss shifted so i left it in neutral. Were you tuned? At what HP and boost pressure?

 

Scares me about going FI in the near future

Goodluck brother...

 

yeah, I was just cruising, no mis shifting or anything like that. It hasn't been running all that heathy. hesitation in mid rmp. My car has been tuned... 501whp @12psi on unichip something appears to be consuming juice, cuz my battery was at 12v (was at 13.7 or so a week ago. Almost feels like a power failure from improper voltage.. dunno, just wild guessing at this point..

 

did you jump the battery to see if it would start from that? Does it run over, but just doesnt start?

 

IMO...

battery shouldn't have caused an issue while driving. The alternator is supplying the current at that point. The battery at 12v while driving indicates that it's not receiving current from the alternator (which should be around 14v).

Check wiring and/or replace alternator = problem fixed. If you put in a new battery it will work till you drain it, then die again. You could test my theory this way

 

Do you hear your fuel pump when you key it to the on position?

 

Sorry to hear about this. Check the alternator plug.

 

definately could be a fuel pump issue......

I've had 2 walbros go bad on me....one was my fault.....the other was just a bad unit from the get-go.

 

Fuel pump, Altenator, UNICHIP.

Take your pick.

 

Fuel pump

 

If you have a FPR with gauge, just check that.

 

I am guessing unichip.. there are 2 other threads with simular symptoms all running unichip

 

If your voltage was 12v while car was running, that points to alternator.

If the car died, then the voltage dropped to 12v, that doesn't point to the alternator. If this is the case, fuel pump sounds like the issue...

 

yes but if the battery is 12v then the car is running off just battery.. and would still be enough to keep the car running till everything shut down.

 

We are more than happy to help you out, if you want to tow her over.

 

fuel pressure gauge FTW!!!

I knew exactly where to look when my car died.......my gauge read "0"
