UNPLUGGING INJECTORS GOOD IDEA OR BAD IDEA?

I posted the other day about a 2003 6.0 that is missing. I put a code reader on it but it didn't tell me much of any thing . My question is can I un plug a injector to see if it has an effect on the missing without tearing something up ? I really need to hear something from somebody about this or it will go to the dealer and i'll pay big bucks for someone to tell me whats wrong with it. sorry for my impatince but this truck ain't my toy it's how i earn a living.

Yes you can do that.

How ever all the dealers around me charge 100 dollars for diagnostic. I used to pay them to confirm what I believe was the problem. 95% of the time I was correct. Then I would do the repair myself.

But to answer your question. Yes you can unplug an injector to see if that is the one missing.

To help you out. For some reason I hear a lot of the 6.0L that have a miss end up being the injector for the number 6 cylinder being bad.

it could be any injector from 1 thru 8, there is no pattern or reason on which injector will fail, dont assume #6 is bad, cause you could possibly be throwing your money away. you need to take it in and have a power balance ran on it. it will show you what cylinder is missing in real time as it is happening. the dealer charges you what they do to help pay for the 10k IDS diag tool that they hook to your truck to help and aid in diagnosing your problem. take it in and bite the bullit. after you know what is 100% wrong, then make the decision then if you want to repair it yourself. also as for the smoke it really depends on how the injector is failed (stuck open, gummed nozzle, intensifier piston failure, popet and seat failure. just because ther eis no smoke doesnt eliminate injector issues.

Call around to some local Diesel shops and see if they can run the test. I had a small independent shop check mine out. I called them and they told me to bring it in about 3pm and it would be 80 bucks. I went, they checked (number 6 was bad) and went to pay and the owner said no charge, just keep them in mind in the future in case i need some work done. It took the tech about 5 minutes to figure it out. So if you need a diesel shop in Weatherford Tx...
