Hi Tony, Please email Eric Baugher with your phone number, we have several Ram 500s that are giving us a fit.

Would like to talk to you about some issuse but had an old number for you at the shop. Erics email is GPAERIC@aol,com or TEAMGPA @aol,com
Thanks, Tony for your time .Ron Stahl

Thanks Chris, I'll give you a call Anyway the more help the bettr on this one I think

500
 

I'll get it going. give me a call also
prime the pump so fuel is to the front cover, purge your tank and refill it. take out your glow plug. Pull the coil way out. not like the manual shows but way out to a qaurter of an inch or so.
it doesn't need to be coiled, just pull it out. I gaurentee it will start.
charge your battery. and turn your festo valve on for the fuel.

set your perameters.
glow plug 50
start pulse width 90. (to start with, we'll lower it after it runs ok)
start gas 55. we'll adjust that after wards also.
do every thing here and it will start. :p

Re: 500
 

Start gas 55 ???

Mine had 75 as the default. Why such a large change ? Is Maryland THAT cold ? ;-)

well tried those inputs yesterday it will not run. or even light off the powermax. I am very frustrated with it since we have two other RAM 500's and they both run ok. The first one was setup for me at Superman and to tell you the truth I don't know where it is set at. The second one refuses to start unless the gas is at 35 today the temp was 85 when we test flew the Starfire, The last one one that won't fire has been a thorn in my side for the last two days. we have over $100.00 of blown plugs with the plug set at no higher that 050 and no lower than 040. the gas has been everywhere from 30 to 75, and it does 1 of four things
1 doesn't even fire the powermax
2 if it fires it then blows the plug
3 if it fires it start s ramping and puts itself out
4 fires ramps and then gets to 47,000 and then flames out
I don't want to get into who has a better engine but this thing sold two jetcats to the other guys thinking about an engine. the waas nothing I could do or say to comvience them that they all aren't this way. Any help you guys can give is well appreciated

It might be worth sending that engine to RAM. It's possible something could have slipped out that wasn't quite up to spec. Sounds like you've tried everything imaginable to get it running.

start gas?

If you are using 75. That means you're using less propane.
The lower the parameter the more propane, the higher the # the less propane.

I set mine so when it fires up there is very little or no fire at all.

Temperature plays a part in this. If the parameter is set for a 60 degree day, and then you start your engine on a 90 degree day the propane preesure is greater and you'll have a little more flame.
Mine happens to start perfectly at 55.

Hello all, Thanks for the thoughts and calls. I finally got it to start and run repeatedlly yesterday. I started the day with three fresh charged batteries and a new ECU and Temp probe. I was able to deterimine that after thinking about what was happening that even thought I was following the instructions to the letter; the ECU or probe was seeing an over temp that wasn't there or was under temp at gas start. Well it was the temp probe and not the Ecu's yesyerday i got it to run by first changing the ecu but the probe was after a few seconds of running not showing any temp so I shut down the test.Somehow someway it was also causing the plug to fail, don't ask me how or why but I ran the engine all day with the same plug after the probe change. We tried a new probe and the engine is very sensitive to how precise you place the probe into the chamber. If you place it as RAM says the engine always over temps but by inserting it just a few thousands farther the engine started and ran every time. So for those people who are having flame out problems with the early ones I can bet you that this is the problem or at least one of them. Thanks again, Ron and Eric.

Ron, I do remember that they had a batch of bad thermocouples at one time. If the thermocouple shorts to the outside surface and (of course) then it must short to the engine case, you will blow a plug (plug is grounded to case). Sounds as if this was what was causing your high $$$ plug investment. Talk to Bob Price, he definitely knows more.
