hi everyone

just a little problem, sometimes on take off first thing and if its been sitting for a while it looses power then comes good for rest of time. usually it only does it once or twice then comes good again and doesnt do it again until its been sitting for a while. got it going on petrol, and other than that it starts first go and runs ok on petrol

the fairmont has following

1. its using a xr6 ecu with a standard fuel reg and engine (wasnt a problem till now as was mostly using gas but that stopped working and at moment using petrol), would it be a good idea to put a standard computer back in or fit the xr6 reg, wondering if the mismatched ecu and fuel reg have anything to do with it.

2. have replaced the fuel pump and holder and fuel filter, need to replace injectors but havent yet replaced them anad thinking that the injectors may be a little blocked from when it picked up all the old stale petrol in tank. when pulling the old ef sender out the earth terminal for the sender had varnish on it and the assembly smelt like varnish as the petrol had gone off, but now ran a few tanks new petrol to clean out the old petrol but put another fuel pump in to get it running and now the old petrols out the tank put a new fuel pump and assembly in.

3. when the water pump leaked it made a mess near front of engine and crank angle sensor, would that be a possibility shouldnt be though as if it was it wouldnt even start and run.

4. when the head gasket went it was blowing steam out exhaust, was wondering wether the oxy sensor might have been affected, is there a chance the cat converter might be blocked.

5. the head gasket has been patched up and is better still got to keep checking it.

hopefully now youre told a little about the ef fairmont that it might help you lot

thanks
