    6.0 possible injector issues

    I’m not concerned about the voltage output of the FICM. I’m concerned about the low input to the FICM and ECM.

    6.0 possible injector issues

    Load test the battery’s. Then check the alternator. After that it becomes a lot of chasing and looking usually. Battery’s are the most likely reason. But a weak alternator isn’t uncommon.

    You’re absolutely correct. It’s unfortunate that we lost Ron. His FICMs treated many people very well too.

    6.0 possible injector issues

    I keep a spare new harness around for this reason. I have the connectors for the end of the harness as well. But by the time I charge $30+ for a connector and labor to swap the pins over, it’s almost as much as a new factory harness. I keep the plugs around in case I break a clip on one while...

    6.0 possible injector issues

    If it’s in the harness then the FICM won’t change anything. The low voltage pre FICM is not good. We’ve brought this up and it needs to be addressed. Right now you just have to chase one issue down at a time.

    6.0 possible injector issues

    If I knew nothing about the truck other than those four injectors were all acting up, then I would be looking at the FICM or the plug between the FICM and the harness. I typed what I typed previous because it seemed earlier that you were dead set that the FICM was fine and that once you zip...

    6.0 possible injector issues

    If you’re like me then throwing 4 new injector in, probably isn’t a financial expenditure that you’re looking forward to. If you’re not wanting to chase a wiring or electrical issue and you’re pretty sure that it truly is the injectors, you might consider marking all of the injectors 1-8. Then...

    6.0 possible injector issues

    It’s very interesting that it is those 4. Could be coincidence. But those are some steep odds for those 4 to have failed at the same time. Those are all on the same driver in the FICM as stated earlier.

    I missed the running part in “running compression test” lol.

    Running compression test... How to

    Pull all the glow plugs. You’ll be testing every cylinder at some point. So you might as well pull them all. Plus this would allow the engine to spin over easier. Easier on the starter and the batteries. Next don’t turn it over with the key. Turn it over by using the starter wire disconnect...

    Did you go with a DSP setup on your tune? Meaning can you change tunes via a switch? Or do you have to plug in your EFILive and load a tune? If you have a DSP setup then fleece I believe can write your tunes like you’re wanting. If you don’t have DSP then you might enquirer about upgrading to it.

    Hit an 8 point with a kicker last night doing about 60. 2015 Silverado Pulled him off the road so nobody would have an accident.

    Not at all! I want all the eyes on this as possible. I appreciate any knowledgeable response and encourage it. Thank you @bismic1 for getting in on it.

    6.0 possible injector issues

    Let’s back up and pretend this is the beginning. His scanner shows two injector electrical faults on each bank. Ok. So. What’s the next step? Because I’m on the road and can’t type a novel. Let me leave this with you. It can be argued what the correct path is. But this is a decent one to take...

    6.0 possible injector issues

    The FICM, the FICM plug, or wire harness are probably the culprit there. The FICM to injector wiring harness has two plugs on the FICM. One plug controls two enjectors on the drivers side and two injectors on the passenger side. Same for the other plug. Typically a fail on two injectors per...

    6.0 possible injector issues

    if You aren’t getting a reading on the MAF then you need to determine if it’s the PID, the sensor, the plug, or the wiring. The PID I can’t help with. I don’t use torque pro enough to determine. The sensor, the plug, and the wiring can all be checked with a multimeter.

    Alright. Is that MAF volts?

    6.0 possible injector issues

    What myself and the other guys are asking you to do by selecting all of the correct PIDs and getting a good complete KOEO test completed, is to not only help spot a possible issue; but also to establish a baseline. Once we verify that everything reports correctly KOEO, we can move on to the...
