Are you familiar with the propane injection system? If so can you tell me what tests you have run so far and what was inspected? Do you have a fuel type selector switch (to choose between Gas and Propane)?When did this problem start and what is the temperature outside? Propane will not convert from liquid to vapor fast enough, if it is too cold outside. Inspect the plumbing between the intake and the regulator. If there is a leak in the plumbing. The diaphragm inside the regulator will not move or open (to let propane flow to the engine). The regulator can malfunction if it becomes clogged with sludge from the propane. They sell a product that can be added to the propane tank. It is used to keep the fuel system clean. Please write back. If you have more details or information I would like to help. Good luck.

I have a 2014 z930m that is fueled with propane. It runs good for a short time then it starts to lose power... like it not getting enough fuel... the regulator gets all frosted over... is that normal?

Could be!! Propane has to have room to expand. But when it does expand it gets cold. The fuel draw from your motor is more than the tank can provide. Sometimes it is because the tank is to full and sometimes the weather is to cold. Get a heating jacket and keep it around 70f. If it still ices up might start looking for a new regulator

My 2002 gmc 6500 propane run truck ran out off propane i have sence added propane and still the truck won't start what do i have to do to get it started

There is probably a safety device that activated when it ran out. If its a factory fit consult the manual or dealer. If its an aftermarket fit then you should have had info with it. Who 's make is it?

Truck runs on propane will not start

What do you want to gave from the message that you have left? There are several components that make up propane system. Also the trucks ignitions components will remain the same. To better help you I need to know as much as you can tell me. Year, make, model, engine size, any light on or flashing, on the gauge cluster, any drivability symptoms, any repairs performed recently, anything replace or tested, and are you familiar with the mechanics of the propane system? The same rules apply. The engine needs Fuel and Spark to run. You will need to determine which system has failed. From there you can narrow down your search and in time find out what has changed or stopped working. Also look at the trucks maintenance history. When was the last Tune-up performed, has anyone used the additives that are available to keep the sludge (From the propane tank) from clogging up the system. Please write back with more questions or information, good luck.

Where do I adjust the rpm on my 1991 dodge caravan?

you can not manualy set the rpm on your dodge caravan, it is set by your computer and your idle air control valve, if you are having problems with your idle being to high or low you may need to replace your idle air control valve, go to your local auto zone or auto parts store and get a new one, they are pretty easy to replace,just a couple of screws and a electric connection plug, the auto store should be able to give you the location of the part on your vehicle of where it is located.

I have a 1992 dodge dakota that gives me a code 27 n tells me cyl.#5 misfire, have checked compession n its good ,dist. good spark is good ,replaced injector n computer tells me faulty control module n it...

Hi there,
Have you tried vacuum leak test?
What you would need is a common shop propane torch.
How you use.
1. Start your engine. take the propane torch (Don't light it!!!) crack open the valve.
3. point the valve at each vacuum fitting on the intake manifold.
what your doing is if there is a leak, the propane will be sucked into it.
This will cause the ideal to rise. When it rises you have found your leak.
Also check where the intake meets the head.
If you have a leak it will cause the effected cylinder to run very lean (to much air to fuel mixture) and cause your misfired cylinder.
I hope this help. Give feed back if this helps anyone. Fixya
