1.6 Zetec - doesn't like to start

[Davey]

I'll put my money on an air leak, probably one of the small plastic hoses attached to the throttle body and most likely the one underneath at the rear of the throttle body that you can't get at without removing the throttle body and inlet manifold.

Thanks Davey, I'll try and get a look at those today.

Have you tryed swapping the ECU some times just because it says it's fine does'nt mean it is. Also have you looked at the cat,done a compression test? often over looked by men with plug-in toys and laptops go back to basic mechanical problems.

I tried a compression test but for some reason the tester wouldn't screw into my spark plug holes. I know the threads are the same because my plugs fit in the adapter that goes on the end of the tester to allow it to test bigger spark plug holes

I got someone else to try attaching the tester and they couldn't make it go on either. I'll have to find a friendly mechanic and get him to have a go.

Not had a chance to take off the inlet manifold yet and should have a chance to try my mates ECU this weekend.

As with Davey, my first thought would be a vac leak.

A point worth noting,bad coil packs can damage ecu and will stop injection of fuel by stopping them earthing.

Somtimes MAF sensor shows no faults and causes loads of problems,try running with it disconected.

My money is still on an intake system air leak.
