CGT stalling

[Jeroen Bruintjes]

Hi list,

Since yesterday my 1985 CGT 2.2 has developed a really weird 
problem. Starting is next to impossible and when doing so, I smell 
strong petrol fumes from the exhaust, like the engine is flooding. 

Now, the car is equipped with a propane gas installation. I can 
manually switch to lpg. Starting on lpg is very difficult (this is 
normal), but it runs fine. So no ignition problems.

Cleaned al contacts of the lpg system yesterday, since they were 
corroded and might prevent the switch back to petrol. Everything 
ran fine for a while. I could switch from lpg to petrol and back - so 
the fuel pump and the injectors are all fine, smooth revving to 
redline here on both fuel types.

An hour later, the problem was back. This morning too... took ages 
to start on lpg and once it did, a terrible petrol-smelling cloud drifted 
by, indicating an engine that was completely flooded... weird. I park 
it, rev it to 4000, switch back to petrol and it completely dies.

Just a few minutes ago, I suspected the fuel pump relay. Pulled it 
and without the relay, the car starts perfectly on petrol like it 
should, but dies within a few seconds. I'm gonna try swapping the 
relay as soon as I find another one. Could it be the source of my 
problem?
