ok i have a bosch 044 fitted to my cosworth and its got a really bad splutter as if on 3 cylinders but once its right up in the rev range it seems fine. ive noticed that when the ignition is switched on the pump only primes for a second not the normal 2-3 seconds is this normal? ive replaced the cps cts phase sensor (gapped correctly) new spark plugs genuine 071`s its running stage 3 msd chip 803`s T34-55 3 bar map sensor etc this car has had my life and all im doing is chucking money at it with no success! can somebody please tell me where im going wrong? thanks in advance!!
