will sugar mess up a diesel? i found sugar in a chop saw i had in the back of the truck today...I cant help but think it might be what is wrong???

OK my 05 is really acting up if you rev er up in park or neutral say to 2200 rpm the motor just hangs there banging out I can take my foot off the throttle and it will just sit on 2200-2000 rpm for ever until i pull it ino gear or turn the truck off????? It sounds like a JAP ROD running on the rev limiter popping and missing. The reason I noticed this is the truck has started idleing really rough and I tried patting the throttle to clear it up like an old gasser. The real issue is that the truck has started pinging really bad while exelerating. It sounds like an old gasser that the timming is way too far advanced.... Any ideas I went threw the rokers already and the lash was pretty good. I found a thread about the A/C wires rubbing and causing the motor to run bad. but my wires looked good.It really sounds like detonation.ANY IDEAS PLEASE?????

 

If you really think that, pull your filter immediately and inspect. Sugar will not "break down" in the fuel and will clog up the filter in a hurry. If you do find sugar in there, be prepared to drop the tank and do a full fuel system flush.

 

You already got your injectors I will bet you.
A guy I use to work with has trashed his ex's mom's vehicle (the reason they broke up) with sugar. It acts just as dirt or sand would in your fuel hard as hell on injectors especially when pressure is being added.

 

i inspected the filter on the motor and it looks clean is this the only filter?

 

Yes filter in the canister located under the fuel rail and behind the cp3. You need to take it to the dodge place and have them do a cylinder cutout test/injector cutout test can be done in ten minutes with a drb scanner and some know how. Saves lots of money and time. I would almost bet your rough idle is due to a bad injector. Also drop the tank and push the fuel lines with a air compessor to clean the lines to the filter out too.

 

If you are familiar with MYTHBUSTERS on discovery chanel, they did a huge experiment on sugar in the gastank. It never did any damage at all to the engine. That was a gas engine. Don't know what it would do to a diesel.

 

I wish I could find out wich sorry dog did it if it really has been done.....I guess I will be buying a loking gas cap . I had a wheel bearing go out on the truck today too. some of us have all the luck. 84000 and a wheel bearing geeezzzz.
