She died.....quietly

[007]

To pile on here...I've seen this movie myself...

You can pick up a new ICM for less than $20. Try it, and if it does not solve the problem, put it in the glove box and keep it with you. If it solves the problem, go get another one and test it (to make sure you have 2 good ones) then go and put that one in the glove box...

If you pull a plug then put it back in it's wire socket, then make sure the plug is grounded - it should spark when cranked.

CJim7-Try this---Run a jumper wire from the POS(+)side of the battery, to the POS(+)side of your coil.
Now, see if it starts.......
If it does(don't run it long like this-pull the wire to stop engine)your issue could well be ignition switch related.

That would be a good possibility. From what I have seen, the coil, pick up coil and icm issues go bad gradually. Then another of the many possibilities could be a frayed wire or fusible link.

I'm going to push it into the garage tonight and take a look at things.
Thanks for all your help guys, I'll keep this thread updated with what I find

 

[CJim7]

Quick update:
After it sitting for a few days, it started right up. Ran just fine for about 10 minutes and then died. The manner in which it died indicates I ran out of fuel (I think the tank was low when I started). It sputtered, then died.

I'm going to try it again with a full tank. I want to see what it does after the engine is completely warmed up.

Does the ignition control module, pickup coil, coil, or any other part of the ignition system do this? (run when cold then die when warmed up?)

Both the ICM and the coil can do that. More likely the ICM but any thing is possible. Let us know what you find.

X2-I'll add the fender mounted ign module will also do the same as the dizzy module and coil.
When did you last change the fuel filter?

[CJim7]

Thanks for the responses guys. That gives me somewhere to start.
LG, the propane system doesn't use a fuel filter. It's pretty much a straight shot from the tanks to the engine.

I have seen some LPG set ups that use a porous Bronze device for filtering.
Have you tried a different regulator on the LPG tank?

My regulator is a stand-alone unit. To be honest, I'm not sure whats inside it. I have my heater hoses plumbed to it so it circulates radiator fluid (to keep from freezing) but other than it allowing the lpg to expand into a gas, I don't think it's too complicated.

It also has an atmospheric pressure regulator which is nothing more than something to equalize inside/outside pressure. It consists of a simple filter....which I checked to make sure it wasn't plugged.

I ask'd because LPG tanks can develop a good amount of water in them, from condensation and that mess's up regulators and such.

I didn't know this.
the only other issue I have ran into was a bad o-ring on the fuel line that caused a loss in pressure which in turn started freezing up the line. That made it run bad enough to lag the engine and make it hard to keep running. At first I suspected that may be the case all over again, because the engine would not start back up.... but a quick inspection showed all was well with the fuel line.
I also checked to make sure I had antifreeze flow through the regulator, which it does. So I don't suspect any freeze-ups in the regulator at this point.

 

[Lumpy Grits]

The issue I spoke of is common in forklifts run'n on LPG.
This I learn'd from the guys fix'n them......
Something to consider especially if the sun is directly on your tank.
Same reason you should always keep your gas tank full.

[CJim7]

I've ran it in every condition I can think of and the hardest time I had was when it was sub-zero.
Dead of summer didn't affect it to much....winter was challenging

 

[Lumpy Grits]

Is there any way you can ck the line psi? To be sure you have the psi need'd for the LPG system to function.
Have you done the soapy water deal on all the LPG connections, just to be sure there's no leaks?
LG

 

[CJim7]

I haven't yet. The nice thing about it is on the pressure side, you know if it's leaking cause it will freeze. After that it's just the regulator hose to the carb.
Pressure is all determined from the tank itself I suppose. And I've ran these things empty...never seemed like there was a pressure issue. But who knows

I'm going to run it again and see how long it stays going. I'll check for spark before I do, and again if it quits. I have enough pane in the other tank to run it to operating temp.

 

[Lumpy Grits]

You have a regulator to 'level' the pressure out into the 'feed' line.
I have had regulators leak and there was no ice-just the smell to follow........
Good luck-Fingers cross'd.

I'm curious as to where your propane tank is located? Can you post a picture. Back in 82 our Chief (Police Department) decided to switch all the vehicles to propane. The ran like on it. Hope the system has improved since then. Also I hope it never vents on you. Here is what happens when one vents. This is a training exercise but you get the idea of how hard it is to put out.

This is also a good one to watch.

Just be careful. Any leak is dangerous. The freezing line you talk about is the first sign of trouble and should not be taken lightly. Good luck with getting your problem resolved.

The tanks are mounted just behind the front seats. I've ran this system for 5 years now with no issues. In fact, it's ran flawlessly. The icing up was an o-ring on the line....and a good lesson on propane upkeep.

I'm still more than 87½% leaning towards an electrical issue. I just need to find the time to get out there and mess with it.

 

[Lumpy Grits]

How full are your LPG tanks now? If over 60%, I would say you may well have an electrical issue and not a fuel delivery issue.
