I wouldn't trust the factory gauges as far as I could throw the truck. You really should get the probe on the alt output lead, and ground to see what your alternator is doing voltage wise (DC), should be in the 14.4-14.6 range. Then I'd switch to AC, and do the same test. Shouldn't be any to speak of.

Problem with only testing free flow on the fuel is there is no way to test "pressure" what you have is flow at like 2 psi (fittings, lines, etc.) Everything changes when there is restriction to flow. That's when you see what the pump (any pump) is made of. Also remember that at idle and low rpms, the engine actually draws a vacuum on the fuel circuit. I know it's been debated, just pull the fuel pump fuse while it's idling, it'll cackle, but stay running. Just imagine how happy you'd be if you had a gauge where you could watch it under acceleration, and the pressure fell to 5-10psi!! I've seen it. Way better than pulling injectors (and paying for them!)

Your IDM is neatly hidden between the driver side fender, and the inner fender liner! Extricating that item is a real PITA. Another item I would trouble shoot well prior to replacement. You did check the harness that crosses the driverside valve cover right?

neck, i checked voltage @ the fuel pump and i was getting 10v ( batteries are low from trying to start it) the pump comes on when the acc is on, but it shuts off after 15-20-sec... i tried hooking up a gauge to the fuel bowl but i got 0 pressure ( the bowl was still empty from where i drained it to hook up the gauge) ???

[CPUNeck]

So that doesn't sound good. That bowl should fill in like two to three cycles of the switch. I was kind of afraid of that. Obviously first you'll need to get the volts up, then do some more testing of the pressure. You certainly won't go far with 0 PSI

[Dirtcheap]

yeah but at that pressure my mileage should be way up ... im gonna drop the tank and check for plugged screens/lines etc.. after that im kinda at a loss for stuff to check..

Dirtcheap my 02 Ex did the same thing 2 days ago and a year ago when I was running homemade bio. I know this sounds too simple for a fix but what I think is problem is fuel with a low cetane level. Get a bottle of DieselKleen with cetane booster pour entire bottle in tank( double dose ). Take truck for a drive to get cetane booster mixed in tank and through fuel system your truck will run rough a first but will evenually start running great. I too thought it was my fuel pump but tried this first and it worked! Hope this helps - if it does don't tell the wife!

[Dirtcheap]

mniebel.. i run diesel kleen all the time... im back to thinkin its something in the tank/lines..

[Dirtcheap]

im happy to say i finally got the X running after alot of heartache and cussing, and $$$$$... now for the embarrassing part... the cause of the problem was a kinked hose on top of the fuel tank ...just in time though as im now having problems with my D-MAX... thanks for all the input and advice...

[klhansen]

Awesome!!

I hate it when it's something so simple. Like the time I had a gasser that would cut out and backfire. Thought I had it tracked down to the resistance wire between the ignition switch and coil, and cut my hands to ribbons replacing it. Turns out it was a loose slip-on terminal on the coil. The fix was to squeeze it with pliers to tighten it up. [insert forehead slap smilie here].

I couldn't resist looking back thru the thread and finding this in post #15

Not wanting to toot my own horn, but it could have been much less of an ordeal.

I'm glad you're back on the road, (and I'm sure you are as well).

As a consolation, you have a new toy (AE) out of the deal.

[Dirtcheap]

so true... at least i can justify it to the wife as follows... "honey just think with all those new parts there will be less that can go wrong next time on vacation "

I really didn't offer any advice but followed your trials. While it does make you feel kinda foolish, you learned a lot about your truck. (positive thinking) after all of that, it should give you some dynamite service for years to come. (You really didn't tell you wife what the actual culprit was did you?)
I'll always remember the kinked fuel line if my PSD starts acting up.

Is it very expensive?

[Dirtcheap]

ratio... there a "few" places... the main place is t-gil fuels over by town and country plaza, theres a station on the corner of new warrington and jackson, i think they sell it on N.A.S... i havent really been keeping track lately as we've been making our own for over a year... as for cost it just depends, it tends to stay close to #2 (within .20-.30) i used to buy mine from t-gil... the trick with them is to watch the other local stations as the price goes up and down, then hit them up... if you could find a steady source of oil i'd try making my own, is not hard

[ManTruck]

Dirtcheap, OUTSTANDING that you found the problem and all is well . Always seems to happen just when it's most Inconvenient.

As a follow-up, what do you attribute the kinked line to? Was it something you threw in the bed denting it thereby kinking the line etc... I'm not too familiar with the fuel line path, was it on top of the tank?

My reason is, is this something others may experience over time or an extreeem case.

[Dirtcheap]

mantruck, i wish i could say it was not my fault but i'd be lieing... when i installed my airdog i cut the feed hose about 8inchs too long, and i guess over time it shifted,moved whatever and wound up kinking... i dont think it would ever be a problem for any stock trucks or excursions like mine
