I'm going to check out a 2005 6oh auto 4x4 tomorrow. Guy says cel is on. Said its been sitting for 2mos or so and he drove it the other day and its got a little misfire. Truck is going cheapppppp and need to know what the possibilities are and what's common? Cps? Hpop? Bad injector? Its got 200k miles and looks VERY well maintained otherwise.

 

misfire is usually an injector/FICM issue

 

And these trucks throw cels with injector issues right? Do you think I need an all new injector? If I get new injectors, I'd go with some stage I or II's; how much are they for trucks?

And what's ficm? Are they easy and cheap to replace? If I hook this truck up to a scanner at autozone will I get an accurate readout of what's going on with the truck or motor?

 

i dnt think the injectors will throw a cel but i have heard people say that some FICM will. you can get the ficm fixed pretty cheap lot cheaper than injectors, but the cel maynot have anything to do with the misfire either

 

Its all about codes. if you have a p0611 code replace the ficm first and foremost. a new ficm needs to be programmed, with a good scanner do a injector buzz test and listen for the 8 good clicks. they go in order if you hear a weak one or dont hear one when you should then that injector should be replaced.

my shop pulls the injectors if we suspect more then 4 of being bad and send them out to place in so cal that will test them for us.

im doing head gaskets/oil cooler on one right now. we sent injectors out to be test and 7 of the 8 were bad. customer said put 8 new ones in.

 

Good deal. So do you think that I should pick this truck up for lick-my-******* cheap and roll the dice then?

 

You're not terribly far from me, where is the truck located? There are a few ways to tell what's wrong with this truck, but more info would help.

You're thinking in 7.3 terms, we don't really have stage 1 and stage 2 injectors. They go off of volume, so stockers are 135cc, most common upgrades are 155cc 175cc 190cc etc... you wouldn't go bigger than 190's for a daily driver, an even at that it'd be smoky. Tuning and turbo would be key there.

I would test the FICM on the truck, that can be done in minutes with a multi-meter. Check the sticky at the top of the page. Bad batteries could also cause these issues too, especially for a truck that's been sitting for a couple months. It's amazing how poor they run with junk batteries... they wont even shift right.

Pull the codes and get back to us. This wouldn't happen to be a white cc/dually 6.0 would it? Saw one on c-list a month back out that way for like $5k... about the same amount of miles. Thought about picking it up for a cummins swap.

 

No its not a cc dually... But I'd sure pick that one up too for 5g's .

Thanks for the quick education on 6oh's. So these trucks won't even shift right with crappy batteries?! Good to know . The truck is kinda out in the springville area tho.

 

Everything is electronically controlled on these for the most part (including the trans) so when voltage drops, sensors and controllers start doing funny things.

Bad batteries can even simulate a dying FICM. That's why when there are issues with the way the truck runs it's always recommended to have the batteries load tested before even trying to verify components are good.

Do you have access to a scanner? You can tell a lot with a labtop and 5 minutes on a 6.0.

 

No I dont have a scanner.. I do have a laptop though..
