Fuel Injector wiring.

[Turbo Habanero]

So I found boost leaks and fixed them car is picking up alittle better.

My check engine light comes on about 1min after driving and resets everytime I turn the key off and on.

Code 11 is the only code.

 

[Cyrus]

what was the problem with cylinder #5? how'd you fix it?

 

[Turbo Habanero]

Turns out the missing was actually caused by the number 3 fuel injector

 

[Turbo Habanero]

Could code 11 be caused by bad battery terminals.

...Code 11 is the only code...

It's always going to be the only code.

Could code 11 be caused by bad battery terminals.

Yes but unlikely.

 

[bioskyline]

code 11 is ecu fine, no codes stored.

 

[Turbo Habanero]

Yeah I knew that I just felt like I needed to specify lol.

My harness in the passenger front tire wheel well got chewed up by my tire real bad could this be the culprit?

 

[jetjock]

code 11 is ecu fine, no codes stored.

Nope. No codes set is represented by repetitive MIL flashes 250 msec long with 250 msec between them.

I said 11 (loss of ECU power) is the only code he'll see because when set it masks all other codes.

So i took a wire brush to the ground and power wire to the battery and cleaned the posts also replaced the terminals and thankfully code 11 is gone.

Now codes 31,41,52 are showing.

The wierd thing to me is everytime I turn the car off and back on the check engine light is off... Until I start driving and even then if i go slow and don't accelerate it does not turn on until let's say 5-10mph.

And then its on until i turn the car off again.

If I turn the car on and off quickly the light will stay, almost if the ecu resets it self if the car is left off for any period of time.

From memory there's a "hot" wire to the ECU that should have power 24/7, sounds like it's missing/disconnected.

The wierd thing to me....

It's weird to you because you don't know how the diagnostic system works. Doesn't mean the behavior isn't normal (which it is) though.

Okay yeah it just didn't seem normal to me because I've never seen it behave that way with codes I've had in the past.
