LPG EA OWNERS WARNING!
Well I haven't been having the best week(I'll spare you guys the story), and yesterday afternoon didn't help much.
After parking my car for a few hours I returned to find my car battery completely drained(New heavy duty battery).
I then attempted to jump start the thing. When I connected the cars together I noticed that my gas mixer was releasing gas into the intake, even though the ignition was completely off. The car refused also to start. I managed to bypass the gas system etc. and get the car started, and drove it home.
I spent today trying to figure out what had caused the battery to go flat, and also send my gas system into a tail spin.
It ended up being caused by my faulty fuel pump. It ceased up internally. This then caused excess current drain along the fuel pump circuit, to which the gas is also connected.
The pump relay had been melted, as well as it's loom.
Here is the scary part.
The relay melted and became stuck in the on position. This meant that while the car was off, the gas was still being released into the engine. The battery eventually went flat as a result of the large current drain from the short, however, in the two or so hours it took for the battery to die, about 1/2 tank(30L) of LPG was released into the engine.
If an open flame were to be placed near the engine of the car during this time, I am quite confident that there may have been some serious explosive results, literally!
For anyone who has an EA on LPG, I warn you that this can be a very dangerous situation. If you fuel pump is not working correctly, fix it, or simply disconnect the thing.
CAUTION: Slippery When BOOSTING!
