Died at the Drive-thru...

[parrie]

My wife & I hopped in my '99 DII headed for vaction last weekend. We made one last stop to get my wife's coffe at MacDs. As we pulled up to the window to pay the truck just died rite there at the drive-thru. Turns over fine, just no hint of running. Had it towed home & continued on to vacation, haven't looked at it since. I'm guessing fuel pump? Any thoughts or suggestions before I begin flayling away at my freshly filled gas tank?

hi...
you can start by checking the fuses....the fuse box under the hood, holds the fuse for the gas pump and the relay, to test the relay you can exchange with other one in the box... they are the same ones......in there are some fuses with at engine figure.. check that ones too....
Hope that this help you...

Hello Memoje,

I haven't had a chance to do any troubleshooting...I was fairly disgusted at the timing of the stoppage of running on the first day of my vacation so I assumed the worse, parked it and walked away for a week. Had planned to check fuses but didn't realize that there is also a relay involved...confounded electronics, I'll take a mechanical fuel pump any-day! Thanks for the response and the info, I'll let you know how I make out.

Ok, finally after several weeks I had a chance to check into what I thought was a fuel pump issue on my '99 DII. Fuel pump fuse is OK. Was going to swap one of the relays to the fuel pump but numbers didn't match so I ended up getting a used one off ebay. Replaced the relay and the truck fired right up and ran smooth. I let it run for a few minutes until it got up to temperature then shut it down. 5 minutes later I tried to start it to no avail...turns over fine but either no fuel or no fire. Has any one had this issue or have suggestions what to check next?

Have you checked the spark plugs? Are they getting fuel? Colour of the carbon on the spark plugs?
A quick pressure check on the fuel rail also would assist in determining if it's the fuel pump.

[parrie]

Thanks for your input Les. Have not checked the plugs as they were replaced along w/ the heads less than 7k miles ago. Didn't think they would be an issues but your right, I should check them for fuel and fire. Checking the fuel rail pressure did occur to me but unfortunately I am not equipped. I'll check with the local garage to see if I may be able to borrow. Thanks again

OK, had plans to check fuel delivery pressure as suggested by Les...once again the truck fired-up w/ no issue however when I put it into gear and hit the gas the throttle stuck and off I went much to my surprise. Was able to get it shut down before I rammed the garage door. Upon closer inspection I discovered that the throttle body is sticking. I understand the operation of the throttle body but not sure if a sticky throttle body could also be the cause of no fuel? Is it possible the sticky throttle body could be giving a false reading to the ECM and not allow fuel to flow?

[Les Parker]

So, it could be a bad T.P.S. or Air Flow Meter.
Do you have a "Check Engine" light on?

[parrie]

Hey Les...I have all kinds of pretty lights on my dash board...3-amigos and yes, check engine light. The check engine light had been intermitant, had it checked and code came up as bad O2 sensor. Replaced the RH front O2 sensor and was good to go for a few days when the check engine light came back on...never had it checked, figured it was another O2 sensor. Is it possible the sticky throttle body is affecting the T.P.S or is it more likely that the T.P.S. is bad?

[parrie]

Removed MAF w/ air tube and inspected the throttle body last night...was definately sticking, inside throat of the throttle body had a bit of gunk build-up from what I pressume to be oil residue blow-by from the PCV tube that connects to the throttle body. Cleaned every thing up, re-assembled, adjusted throttle cables per LR workshop manual specs but no go...turns over fine, just no fuel. Just ordered an inexpensive but highly rated engine scanner, hopefully this will help me pinpoint the problem.

[Les Parker]

Have you checked to ensure you have a good spark?

[parrie]

Initiallly yes, I had spark but i have not checked it again since the intermittant starting and not starting, everything seems to be pointing to a fuel system issue. My new engine scanner should be here today so I hope I can get the issue pin-pointed. Will get back and post results. Thanks

You have cel on but what are the codes?

[parrie]

OK, the saga continues. Plugged-in my new scanner and only 1 code came up...P1509 which I believe is an ABS code? Still apparent no fuel, sprayed a quick shot of starting fluid to see if there was spark and much to my surprise the truck fired-up, this time w/ new symptoms...both the "mode" light and "sport" light are now flashing and truck is in "limp mode". Shut it down and would not start again. I ended up going to a more DII friendly forum and have narrowed down the issue to either a bad crank position sensor or possibly a bad gear position switch. Of course none of the local part stores had either on the shelf, should have the new crank position sensor today. Hopefully this does the trick. Will report back.

[parrie]

About ready to throw-in the towel...replaced crankshaft position sensor, no go. Turns over fine, has spark but apparent no fuel. "Mode" and "Sport" lights still flashing but no check engine light and no failure codes show up on the engine sysytem or transmission system. Any thoughts....anyone....

Oh yeah, forgot to mention that on my 3rd attempt to start the truck I managed to snap the key in the ignition...i love my rover, i love my rover, i love my rover...
