Default Cosworth Starting Problem

Hi all,

Cutting a very, very long story short, I'm still having issues with trying to get the car running properly.....

It's a Mk1 escort running a YB.

- Green injectors.
- T34.
- L6 ecu.
Basically a stage3.

The car has been running lonely for a few years on and off... ha ha

What's happening is, the engine won't fire on start up, it turns over ok, but when I turn the full pump off, after a few revolutions the engine fires and then I can switch the pump back on and the car will idle on its own. The engine does sound lumpy on idle.

I have changed everything in the engine bay, all new sensors, new loom, ecu, fuel, battery, to try and sort out this problem.

Any help would much appreciated as im at a loose end.........

Pete.
