Is this your LPG one?

Nah, a thirsty petrol only 3.2. 

Need to put more of it in then, probably why it keeps stopping.

I may be wrong, but it's my understanding that switching off when the ECU is in the middle of its start-up routine upsets and confuses it. Disconnecting the battery for a while can allow it to reset and start normally.

Ron.

Nah, the ECU fitted to Omegas never really gets confuddled.

The ECU isn't the problem, as it's working off the coolant temp and air temp sensors(and maybe a time delay). It's operator error, turning it off before the cold start program has finished. That doesn't always lead to a flooded engine, only when it doesn't catch instantly.


I used to see this problem all the time; starting the car, moving it, and turning it off, all within a few seconds. Doing that a couple of times in a row is asking for trouble. Some engines are a complete PITA to restart, more cylinders make it worse like V8 Jags. The simplest solution is to let the engine run a little longer before switching off.

Worse thing I have known for this is the Mazda RX8. They do this very easily and a real bitch to sort out. EFI...... the way forward, never have to worry about cold starts and choke again, fuelling spot on for every occasion....Hmmm.
