Engine wont stay running
Im having issues keeping my engine running. It will start up fine but run for maybe 5 to 10 seconds. Im thinking its the injector pulses. I checked the hot side and its getting 12v. I checked between both leads and im getting 5.5v. I also checked the negative lead and positive from the battery and i get 12v. Any thoughts? Could it be a fryed pcm?(vats is tuned out)
Any other possible reasons it wont stay running?
I made a common ground for the harness on the driver side head by the ect sensor and from there grounded to the chassis. Do you think I need more grounds? Could that cause the issue im having?
Any help would be greatly appreciated

check your fuel lines , also how many ground wire on your car ?
-
Fuel lines have 60 psi. I have one ground from engine to frame and a few directly to the frame and some to the driver side head.

Maf is deleted. Ya MIL is on but i dont have a code reader. Ill see if i can borrow my buddies then post what codes are thrown later tonight.
-
what about the air intake temp sensor?
maf can be somewhat disabled in the tune but not permanently deleted; in order to revert to sd mode.
-
I have the iat hooked up but i dont have the intake tube its in hooked up, cuz i dont want to push boost till i get it running.
-
Just checked and its throwing codes as follows
-P0102-MAF CIRCUIT SIGNAL LOW
-P0200-INJECTOR CIRCUIT PROBLEM
-P1637-GENERATOR L-TERMINAL CURCUIT
MIL no longer present
-checked injector balance-all pulsed and recorded pressure drop(atlesst thats what the scanner told me)
-
that 200 code needs to be fixed.
maf code is from the sd tune, which is ok; and the maf not being present.
if the alternator is charging, delete the code.

I know im not getting enough Voltage to the injectors- drops to 8.5v. I have 2 separate banks one for drivers and one for passenger. I used 14 gauge to feed, Is that too much too little? Any other ideas? Thanks man
