Alternative Fuels

Thanks for the info. I will leave it operating. I suspect previous owner was driving it with empty tank, because I keep it full almost anytime. If the pump is gone bad, keeping it submerged would not bring it back. :D I disassemble the pump assembly, it smells burnt. I am waiting for parts to arrive...

You are correct, current setup switches back to gasoline at heavy load. Actually it was switching before I changed vapor LPG filter. After that, I haven't notice switch backs. When it blow the fuse for the first time last year, I changed the fuel filter. It was almost clogged. Running it with clogge...

Now, I am putting it back on wheels... I got "new" fuse box from ebay and going to rewire it. Also, I also order used pump from supercharged engine and expecting it in two weeks. I will also revise all LPG components and connections. Here comes my questions: What is the best practice to manage fuel ...

Then I went to the fuel pump itself. After removing it from the tank I found these: burnt_pump1.jpg burnt_pump2.jpg burnt_pump3.jpg The whole cable from pump to body is burnt. I clearly see this is not the first time this cable was melting. The pump also smells burnt. Anyway, I am lucky the car did ...

Hello to everyone in the forum, I have been away for a long time. Recently I have very unpleasant accident, actually very dangerous one, with my car, 2004 Monte Carlo SS Supercharged with BRC vapor injection LPG system. I bought the car from UK in 2014 as is, and since then I put some 25K km on it, ...

I have not thought about this switching feature... it is indeed flawless switching from gasoline to LPG... you only would know when it happens only by watching light going from red to orange and finally green. I would vote for BRC :-) Can some explain what "valve saver" system does? How can I check ...

Sorry for hijacking the topic... I am always amazed by your knowledge C3H8! I have BRC vapor injection system installed on my 2004 Monte Carlo SS Supercharged. I bought the car with the system installed in UK. The intake is drilled. I can confirm, sometimes it switches to gasoline on heavy accelerat...

Hi geraldm, Very interesting thoughts. Which reminds me, when a mechanic changed the plugs some months ago, he found 5 of the plugs were copper and one iridium. That time I did not pay any attention on this, did not check gaps or what ever... did not even ask on what cylinder was the iridium plug in...

Hi Storm and C3H8, Thanks for your comprehensive answers. I will go further investigate this issue as follows: First I will try switching injectors. (I can do it myself) Then make leak down test. (I have to arrange it with friend of mine) About catalytic convertor, they said it is empty, burnt or wh...

Hi C3H8, Thanks for reply. What do you mean to switch injector? To take 4th and 6th, for example, disconnect them from rail and switch their places, cables, etc? About bad valves, will compression test show/discover it? The "exhaust guy" here said the catalytic convertor is already gone. I consider ...

After some more driving I observe the following: Spark plug is OK, I changed it with another one and nothing change. Spark wire is OK, I changed it as well. Coil is OK, installed new one. Cylinder misfire appears after about 15 km city driving on LPG. It does not appear on highway, I drove some 300k...

I bought cheap ODBII scanner to read codes. There are two codes that appear, no matter if I drive on petrol or LPG. The car runs fine, I do not feel any engine hesitation or rough idle. The check engine lights on after some 10-20 km driving after I clear it. It does not flash. The codes are: P0304 c...

Hi C3H8, I will go to scanner this week. Here are not may scanners able to "read" American cars, actually I know only one :-) The check engine light is permanently on, last time I was on scanner it showed cylinder 4 misfire (like 150 times) and some issue concerning catalytic converter (do not remem...

Hi guys, I have some issues with my new car. It is 2004 Chevy Monte Carlo 3,8L v6 Supercharged with dual fuel conversion. LPG setup is BRC, vapor injection, installed in UK. The car was running and idle fine on LPG. Some days ago I changed spark plugs and wires. Then it started misfire, or at least ...

Hi Steptoe,
Thanks for reply.
Today the car got filled without any issue.
May be it was very hot tank, bad pump or whatever...
