Ford LRG 425 Genie Starting issue

Lift worked fine last fall. Both on Propane and Gas. Sat for 4 months indoors and now is difficult to start on gas, won't run on propane at all. It will crank and fire for a few seconds. I checked for fuel pressure on the fuel rail and nothing. checked for codes and get one blink, then two blinks over and over. I have replaced the fuel filter and flushed the fuel tank and refilled with fresh gas.
I could use some direction. Where it was stored, no mice could get to it so I don't believe there is chewed wire.

Check cam shaft timing before you get too far.

I was just reading through the trouble shooting flow charts. It says with both emergency stop pulled up, turn the key to ground control and listen for the fuel pump to come on for two seconds. I hear nothing.

I might also note that when it does start, it runs smooth. It just seems to be starved for fuel.

I went out and put a volt meter on the power line to the fuel pump. When the engine is cranking, I can see it applies 12v to that line. At the same time I am watching pressure on the fuel rail and see 0 pressure. Is it safe to assume that when the fuel pump is running, pressure should be seen in the fuel rail?

If so, then should I replace the fuel pump, or investigate further?

Might help us to know what model and serial number machine we're working on. I take it this is a fuel injected engine and not carburetor?

Oops, sorry I forgot that. 2000 Genie Z-45-25J SN 15314

I was able to get a helper and the pump is not running even though there is power to it.

Does the engine start/run for a moment and then die, or does it not start/run at all?

I can crank it and it might fire right away for an instant. Some times I let it crank for 10 seconds and it will hit for an instant. If I switch to propane, it will fire for an instant then not fire any more. Switch back to gas and it might run for 1 or two seconds. Occasionally it will run for 5 or so seconds and smooth out, then die. More often it just cranks with no fire. Once randomly it started and ran for about 30 min then died.

Well, I'm no engine expert, certainly not spark engines, I hate the damn things, too many things can make them F...umm...Fowl up. But from what you just posted I doubt your problem is your fuel pump for a number of reasons, just one being it won't run on propane either, something else is causing your problem. Not sure exactly what to recommend here with the info you posted, no where near narrowing down the problem, but we gotta start somewhere. First thing, is the check engine light on when it does run? If yes, that indicates the Ford ECU has stored fault codes. Second, I'd open the lower control box and monitor the LED lights on the start/run module located inside. Start the engine, and hopefully it runs momentarily while you monitor those LED lights on the module, see which ones (if any) go dark when the engine dies. Again, I'm no expert on spark engines, but we gotta come up with some form of diagnostics.

Well thank you for you thoughts. I will do what you suggest in the morning and report back. It does not light the check engine light except for briefly when beginning to crank the engine. It has started and run for a brief second or two several times when I tried. Flipping the test switch only give me one blink then two blinks over and over.

Checked the ignition module like you suggested. Nothing out of order but the lack of sound from the fuel pump when number 9 light was lit. I then jumped power to the pump and it ran. Turned out the ground wire was loose on the pump. All good now. Thanks for your assistance. Some times it just help so have other input.

Interesting thing, I switch it to propane and it dies. Seems I have another unrelated problem there. Any tips on trouble shooting Propane issues? I have a new tank and fresh propane. When I am switched to propane and hit the start switch, you can hear the propane valve pressurizing on the engine. It will not start or even try to run on propane.

Propane is a different issue altogether. First have to verify the solenoid lock off valve is working proper and delivering propane to the regulator. The regulator is more tricky as it requires vacuum from the intake to open it and begin delivery, can't really pop the hose loose and see if propane is coming out unless the regulator has a primer button, but most Beam regulators don't. Have you replaced the regulator or made any changes to it since it last ran on propane?

I had not done anything to the propane side other than a new tank and fuel. I just walked out and switched it to propane to see if the regulator cooled at all. Fired right up and ran smooth. Guess it just needed to warm up. I ran it for about three hours today. Good thing as I prefer propane over gas as fuel to deal with. It burns quite a bit of oil and has an O2 sensor code. Its not keeping it from running and I figure the excess oil being burned could be part of the issue there. I need to spend some time replacing plugs, wires and injector o-rings.

So as for this thread and issues with it running, I believe I am out of the woods now. Thanks again for the support.
