the engine just wants to see an injector to do a bizz test. no need to run the engine to do the test

 

do you guys think I can drive it with #1 not working properly? I turned it off with AE and it makes no difference. But if I try turning off any other injector by itself, the truck lurches and stumbles as I would expect it too.

 

one of those things with my crystel ball being broken. I have no way to advise on that if I dont have a truck in front of me that is broke.

 

thanks guys, ill try that buzz test idea tomorrow. Ran out of daylight!

I'll have to drive it in the morning though, I have to meet my finish carpenter at a jobsite. Hopefully it doesn't blow up!

 

id say you just found your problem.

 

Just makes me mad if it's that new injector. I just paid $550 with shipping for it, I wonder if Innovative diesel warranties them?

 

I'm Sure they will if its bad.for 550 they'd better.

 

That's what I meant. The new motor and all the new components on it.

 

I got the motor from some builder in ALberta Canada through my installer. I think the same motor builder supplies NADP.

THe injectors and other mods were from Innovative.

 

Today, same problems. But no return of glow plug codes

 

Took injector harness from the faulty cylinder and tried it on #3. It worked fine. Tried #7
harness on #1 and got barely a buzz or a click. So I'd say #1 injector is toast yet again?

Why would #1 cylinder keep killing Injectors?

 

I take it you bought a set of injectors, one went bad, and the replacement isn't working right either? Did you send the first bad one back to get repaired, or did they send a different one out? Did the first injector have the same exact problem?

The FICM is the only electrical component connected to the injectors.

Call and get your warranty clarified.

 

The replacement was a brand new one.

AE showed FICM, FICM logic, and FICM sync were fine. Also I took FICM apart and inspected it. It was fine.

One thing that may be worth mentioning. I disconnected the batteries and turned headlights on to drain batteries and KAM.

Restarted truck after 15 min. The truck never did the vgt relearn. Also the truck doesn't idle higher once in a while if it's been sitting idling. It use to idle at higher rpm for a few minutes. I believe it part of the stratedgy to help keep the turbo from sticking?

 

I can tell by the whistle in the exhaust sound my turbo veins cycle every so often

mine only idels higher when its cold outside winter

 

I was wondering if the higher idle was ambient temp related.
