Hello again! I humbly ask for your assistance once again....I asked you guys earlier in help identifying my 1986 Forklift. We knew we had to replace the master brake cylinder and water pump. That has been completed. The forklift would start immediately, then die after about 10 seconds. It sounded great. It was determined that the lift was out of LP, so we went and had it filled. It now will not start. A real forklift mechanic came and checked all electronic parts, regulator, vacuum lines, dis. cap, wires, fuses, etc etc. We smell the LP, Still will not start. The Lift guy gave up. It wants to start, just doesn't....Clue, please????
Also, just dawned on me that I am probably in the wrong forum. I will repost there.
Showing items 21 - 40 of 44 results.
UPDATE! Pulled plug out of new regulator. No Gas. Empty, dry, no smell. Gas going into vaporizor, nothing in regulator. Can vaporizer be removed and cleaned? Will order a new one, but need the lift tomorrow.
UPDATE! The Forklift is STILL BROKE. Was NOT the regulator.....Anyone know a good forklift mechanic in Tampa????????????
in short "NO" lpg pressure and the engine suction will soon do it as soon as you crank her over!!
First of all, a huge thanks to Mr. Foster for his assistance with this Forklift. And, of course, all of you! We have just now installed the new regulator, and now have just 1 question....Does it need to be "purged"?
Also make sure it's not fitted with a switch on the dash that operates between Gasoline and LPG.
I want you all to know how awesome you are. You should truly charge for your forklift knowledge. I would be HAPPY to pay. And honestly, I would hire another mechanic, if I knew one. All the Forklift people are closed til tomorrow..
It could be fitted with a Aisan gas system been a old Toyota

contact me through my e-mail in the profile.
yes it is a 5R, yes it has a doughnut shape air filter, yes it has an Impco regulator. (I am typing what I am told to type) We never filled the LP Gas tank before last Friday.
If your truck has the originally equipped 5R engine that was assemble from a kit form in Torrence, Calif. The selling dealer most likely installed either a Beam of Impco fuel system and pitched the gasoline hardware. If the engine that is under the white top cover has a doughnut shaped air filter, it is the 5R. The question still goes back to which fuel system, because the selling dealer may have install a cheaper vapor fuel system and not a liquid fuel system.
Question. Does anyone know if the toyota 42-efgc15-13405 has a low oil or no oil safety switch???
one possible way to determine if it is a fuel problem would be to disconnect fuel hose from lp tank, then remove air intake hose from top of carburetour( usually held down by 2 bolts, then manually spray carb cleaner into carb in small 2 sec bursts. if it runs as long as you feed fuel it is a fuel problem, if not at least you eliminated one possibility for your problem. Also if this unit has a points style ignition system, check points gap(.017) it can also give symptoms similar to fuel system failure. I did not intend to bash or degrade your service tech, However if you understand the theory of a internal combustion engine it should be able to resolve issue. Also I would check voltage to Ignition coil and B- with keyswitch on and after released back to run position.GOOD LUCK
LOL, I am posting on 2 different sites on this forum. Now my son is in the military, and works on, among other things, forklifts. he is NOT the mechanic that was working on this truck Saturday. Much bigger then this, of course. I am calling him each time you guys post suggestions. So a big THANK YOU!!!! William is trying both suggestions. He freely admits that this is not his "forte". I will post back.
sludge or "honey" as we sometimes refer to it as, is something that builds up inside the regulator and should be drained pretty often, depending on how hot your regulator gets in normal operation, and will cause a starting/running problem. there is a drain plug in the regulator.
I am thinking if getting the thing out off your way is the immediate goal., you may (if really lucky) be able to get the forks off the ground and push the unit by pulling back on the lift lever and cranking the starter for about 10 seconds.
the less quality of gas (grill gas is not always hd5) also causes buildup of stuff in the regulator
Could "sludge" in the vaporizer cause a starting issue? Can it be cleaned?
If I do not have HD5 LP gas, would/could it create this non-starting crap? I am in Tampa, and all the forklift places are closed today, or I would call another mechanic in. Stupid thing is in my way, and is NOT easily moved! :)
There ARE differences, HD5 is the propane industry standard that is required for forklifts since 2004. LP gas does not "go bad" like liquid gasoline that is not stored in air and moisture tight containers.
it is possible to get contamination into the LPG tank that would in turn clog the LPG systems filters (as long as the filters were still there) or the LPG regulator. it is also possible that the LPG regulator is a problem from contamination or non use causing seal failure
Your problem does not sound to me like "bad gas", as much as a failure in the fuel regulation and delivery system.
Okay, just talked with 3 different propane companies. They said there is no difference in LP Gas, and it does not go bad. I found online something about HD10 lp, and the propane guys did not know what I was talking about!
Hmmmmm...You raise a very good question,..We will check this tomorrow...the lp gas was purchased from U-Haul...
michelle;
Was the person working on the LPG system able to tell you what brand of fuel system the truck has? 85% of LPG fuel system not starting are electrical in nature. Does this system have an electric fuel lock off which is controlled by the engine's oil pressure sender. Are all of the plugs firing, and most importantly what does the engine's compression appear to be? Where did you aquire the fuel from? Is the proper grade or is it a commercial grade of fuel. We need to go at this in a systematic and orderly manner otherwise we will end up chasing an imaginary tall tale.
