I have an 2003 Z06. A week or so back it dies on my girlfriend while driving and wont start. Gets towed back, thank god for AAA. Get in at at home and fires right up. Figure it may be the fuel pump system. Change relay, check ground by headlight and clean, check ground at back and clean. Then column lock screws up. Battery voltage at 11.8. Autozone checks battery, says OK, take home charge and no issues. Drive it today after checking bat voltage at 12.35. Running 14+. Going down the road and engine falters and dies for a second, check engine comes on, never push in clutch, engines starts again, few seconds later same thing, charging system fault shows, catches again and is fine.

Pull codes. Lots of history.
c1214 HC ( been there a while, traction screwed up.)
u1096 H on sdm
b0521h, u1255h, u1160h on ipc
u1096h on next one
b0361hc on hvac
b2282h, b2286h,b2284h,u1096h on ldcm
rdcm has 10 codes, b2203, 5, 7, 9, 2283, 87, 85, 65, 73, u1096. door window, locks are screwed, need to fix
u1000h,u1096h on rfa

I am pretty savy on things, understand how electrical works mostly, mech engineer.

What is my best bet. I am scared to drive the car very far. Is redoing all the grounds my best bet at the motor and front frame. what else can be going on.

thanks in advance.

PS, how do i clear all the codes? just pull power? radio then needs reset.

 

Wow... that's a chitload of codes. What year and model is your car? How many miles?

You clear codes by holding down the reset button within each module. Holding down the reset button will clear all codes within that module, not just the one that is displayed (I'm assuming you're reading codes from the DIC and not using an aftermarket scanner). Definitely reset them and see which ones come back.

Have you checked the wiring at your alternator? Is the grounding screw in tight?

 

2003 Z06, 85K miles is all. I will clear all the codes and check the wiring at the alternator tomorrow. thanks.

 

Try the ground on the driver side of the block by the header. Its for the fuel pump.
