I have had a rather hectic week but I hope to get stuck into the car by thurs night. Please stay posted. gw |

GW, I had assumed that you are talking about an EF or EL, is that correct? It is unusual for Ford not to know basic system operation. My understanding is that the single ECU came out in the AU series but only for dedicated GAS. So it can't be applicable to yours as you state Duel fuel.

They all tell me to go to Perth Autogas who have already failed to diagnose the problem on 2 occasions. It is an EL 03/98 dual fuel fitted by Tickford on the 19/03/98 compliance plates varified. Had a quick look at where the clutch pedal would normally mount and there is a gold anodised craddle holding a black and silver box with some wires pluged into it. I will have a good look, check power and earthing etc tonight. Is it possible to unplug and remove the gas controller and still run on petrol? Thanks GW |

Have you checked your pm's Brett, If you can disconnect the vapour hose to the inlet and block off both open ends, then start the car and change to gas and see if it dies after a few seconds. This will partially check the wiring between the two ECU's is intact and you have the correct Engine ECU in there. Cheers TW.

I clamped the vapour hose and the engine stalled exactly the same as when the hose is not clamped. |

OK, that sort of eliminates overfueling, why did you suspect spark? If you want to test that then connect a spare plug or a plug from someone else's car to one lead and earth the other end. Check for spark during the changover period.

I suspected spark because the engine doen't run rough at all at changeover, it just stops. |

At changeover the injectors are stopped, not the spark , unless there is something wrong with the engine ecu when running on the LPG timing map then I doubt there is a problem.
It is looking like a Convertor or Stepper motor issue. Anyway press on with the test of the spark if you like.

Quote: I have loosened the flare nut on the gas lock on the converter and it spews out liquid. I missed this PM before what was the liquid, coolant perhaps or was it thick like oil?

Maybe thats why they call it LPG.
