The fault you describe is similar to the fault common on the Fiesta 1.4Tdci, although the 'injector fault' code is not shown on the Fiesta. The failure to start with the Fiesta is caused usually by a cracked plastic fuel pipe near to the primer bulb, in turn caused by the pipe vibrating because it's not properly fastened to the bracket. Strangely, this does not cause a noticable fuel leak, but allows air in when parked. the fuel runs back to the tank and the car will only start when the primer bulb is pumped. I've also heard of a fuel filter problem causing this. It seems one make of fuel filter can leak air around the plasic welded join where the top plate with the nozzles is connected to the body of the filter. So - if this helps - try to check for air leaks - cracked fuel pipe or loose connector, perhaps?

mickey,

car had been sitting all day at work,when i finished i jumped in to start,it started reversed about 6feet then cut out,would not start again as only turning over,called rac,they came out squeezed the fuel primer 4 or 5 times then it started,drove fine home,next day was fine,day after it did it again but i primed it again and it started,yesterday car started but after 1/4 mile INJECTION FAULT / STOP message came on dash,i then stop switched off and back on again and car has been fine since.

it only seems to happen if car has been sitting lenghty periods of time.

an aftermarket fuel filter was fitted about 3000 miles ago.
