While driving my truck last night,it decided to bog out and die right after I put some fuel in--(co-incidental I think)..I figured my add-on electric fuel pump had once again lost power (something I thought I fixed recently!--loose wire in the fuse box)..but after I coasted into a parking lot,I could feel the pump running,and the truck did re-start after about 5 seconds of cranking,and got me to my destination about a mile away..
When I got there, I removed an in line gas filter I'd installed between the fuel tank and the electric pump--thinking perhaps the pump couldn't suck enough fuel with it being on the suction side..it wasn't clogged ,I could blow thru it fairly easy--but I decided to eliminate it anyway..the truck has a WIX 33123 canister style fuel filter /separator on the firewall too,but no "secondary" filter in the valley pan area like some others like mine I've seen..
This was not the first time my truck has "bogged out" like it ran out of fuel,and it has surged a few times on the highway--but it always fires up again without much cranking,and the weird thing is I can see smoke coming out of the tailpipes as its "dying",so I'm wondering if it IS fuel that its lacking--why would it still be throwing soot if its got a clogged filter??...it wont act up unless I am heavy on the throttle,or am going fast on the highway--around town it seems fine..
I've gone through a list of things that could cause this,all I can come up with is perhaps the fuel shut off switch on the injector pump is failing??--or maybe the return lines to the fuel tank are clogged or restricted??..my engine seems to be more noisy too,the crackling diesel sound is a lot louder in my 6.2 than my friends truck..is that due to it running lean??..
I haven't changed the fuel filter (WIX one on the firewall) since I bought the truck 3 years ago--but it looked recent,and I have only driven it maybe 1500 miles since..took a sample of fuel in a glass jar out of the water drain,it looks clear and no water or other crud in it..with the electric pump on fuel flows freely out of the drain valve,but I didn't try the line that feeds the injector pump for fear of getting it airbound,then I'd be walking home!...
So--anyone got a clue??--should I just waste 20 bucks replacing the WIX filter,which to me does not appear to be clogged or contaminated?..or do you guys think its something more serious,like the injector pump??..the engine runs with a misfire at idle sometimes,always has..sounds almost like a sticking valve on a gas engine--it'll skip,then smooth out intermittently..but once its past idle its smooth..its just when I romp on it to pull out into traffic or pass,that it seems to die out or "flatten",and not accelerate..I am running both the electric pump and the stock lift pump since I got the truck,so I can't say that is causing this..
Its got me baffled--and pissed!..I have very little money and a LOT of things to fix on this truck now..it needs other important stuff like brake work,oil pan,draglink ends..I'm ready to burn the F'n thing...
