'94 D1, wife ran out of gas trying to get to the cheap station I make her go to. I know, I don't need to hear it from anybody else. Anyhow, it had a lot of trouble starting, but I limped it to a gas station to top it off. It still is running badly: misfires, hesitation and threw a code 44 (Lamda from the misfires?) Any ideas? Bad gas? Clogged filter? I'd appreciate any experience...

maybe an air lock. we ran the 95 out of gas a few times. it would run like you say sputtering and carring on, even stall out. after cylcling the key on an of a few times. tricking the fuel pump the rough idle went away.

Thanks guys. I'm off for a filter and something to dry out the gas. My rescuer grabbed a gas can sitting here at work. He thinks it was sitting over a year. Definitely feels like bad gas.

So last night I changed the filter and put in some STP gas treatment. It fired right up and I started driving home. On the way there I felt the truck bogging down a bit, but if I stayed on the gas it would come right back. It only happened a few times, so I thought I was burning through whatever bad was left. This morning back to broke. Won't even idle, just stutters and dies. What do you think? Another filter? Something else going on?

Measure the fuel pressure on the rail with a tester (around $40 at Sears). Pressure should be to spec (its 50 psi on a D2 but I'm not sure about the D1 maybe someone can look this up for you).

DI should be 32-36 psi (2.3 - 2.5 bar)

if water was put in the tank by accident then it has probablly froze in the line. if this is the case get inside and drain all out of the tank.
we just bought a 95 dico that was left out side all winter in cottage country. they had sucken hosed out all the gas for their snomibiles. so the guy hadded in gas from a can that he got from areound the cornnor. the rover started but ran terible. we let it run untill it was dry again. then we added fresh gas from the gas station. once we got the air out by cycling the fuel pump it ran perfect.
so i am thinking that you have bad gas amd now it is frozen . just a thought

If low, means failing pump? Can running out of gas/bad gas kill a fuel pump?

Timmer,

Thanks for the input, but I'm in Phoenix. Could still be water though.

Also, I went looking for the Schraeder fitting on the fuel rail but couldn't seem to find it. Any tricks there?

blake. i would sugest to drain your tank then. get all the old gas out of there. once you got it drained ad some fresh . shake the car from side to side and drain or siphon again. like flushing. add some supreme and hopfully that the car will run proper.
but i cant see if it ran fine then it was run out of gas and now the pump has failed? maybe you never know but try to flush it out. at least it will only cost a few bucks in fuel and wont hurt to try. i mean even if you do take it to the shop i am sure that they will drain the tank anyway. good luck with it

i have "heard" it could ruin the pump as the pump motor is cooled by the gas in the tank. so it "could" have burnt out the motor. on the schraeder valve, since you have a 94 should be the same as my 95. Looking at the engine, on the left hand side, right on the fuel rail, is a little black cap. unscrew the cap, and there is the valve.

Can you use the same tool to connect upstream of the filter? I dropped in a new filter last night, but could it be plugged and causing a pressure drop?

make sure the filter is on correct? there is an 'in' and an 'out' side of the filter.

there is no valve to connect to, but i think there are some tube attachments that you can connect at the filter or at the pump itself, but don't quote me on that.

confirm what your pressure is at the fuel rail first. then go from there.

The plot thickens. I disconnected the fuel line in front of the filter, thinking that I could use the pump to pull the 'bad gas' off the bottom of the tank. No output! I checked the inertia switch, seems good. Stuck a DMM in the plug and saw 12V and 5V with the key on. Sounds like a dead pump. Didn't feel any humming or anything. Am I thinking this through correctly? I've had fuel pumps die on other cars, but it was usually all or nothing. Is the pump something I can fix? Always trying to save a buck.

This is info for a RRC fuel pump, but should be similar:

my pump died last week, but it completely died and truck wouldn't even attempt to catch, as there was no fuel or pressure at the rails.

if you have between 5-6 volts at the plug, and your pump isn't running at all, then pump is dead.

not sure if a pump could just be weak? possible i guess. hopefully nothing blocking flow in the line.

yes, it can indeed be weak.

My Range Rover suffered from a weak pump. it was on the borederline of acceptable pressure 29psi. anything less usually wont run/start.

I would use Starter fluid to give it that bit of extra help. once it was running it was okay though when i gave it a lot of throttle id lacked power becasue ther was virtually no extra fuel to give.

After these symptom is started with fuel filter .. changed it and it ran fine for a few weeks. it seems the old filter was very slightyl dirct and restricted a little bit of flow. with the new filter i once again got enough pressure.

finally one day the pump was jus too week to start, logic and research told me it must be the pump.

i rplaced it and BAM shit was back in bidness. thats when i realized that the fuel pump was the root of my hard morning starts and lack of power in the 3500 rpm range.

Ok. Last night I pulled the fuel pump out and plugged it in and it ran fine. Reinstalled it and the truck would idle, even hold at 3k revs, but back down to idle sooner or later it would cut out and die. I could feel the pump stumbling as this happened. I can hear the relay click when starting the car. The manual says the pump should engage at key position II. Mine doesn't until I turn the engine over, (position III). Is this normal? Maybe a bad relay?

if it's bad relay, switch around the mfu relay with the fuel pump relay. it possibly might be a weak pump though, like Rob says. the pump should run for 2 seconds or so (enough to pressurize the rail) when you put the key in the II position. did you hook up a pressure gauge at the rail yet?

Hi all, my rig doesn't have the Schraeder valve on the rail so I tried installing a gauge after the fuel filter on the supply line. The fittings are flared so I can't seat the connector even though it's the right thread size and pitch. I swapped relays and the problem is still intermitttent. I drove it for over 30 minutes last night and I felt it starving a few times. I think I'll just replace the pump. I just hate shotgunning a problem, especially with my money!
