I'm all out of ideas you've replaced everything I did when mine did the same. Mine was the ecu in the end but then it didn't read at all when pluged in.

ok well thanks for your help im sure someone will no whats wrong with it .

Well mine was timing out. Just adjusted the camshaft back into position. Not sure why it was out but I had exact same issues. Now runs great.

Ok i will try that how did you re-adjust the timing cheers

also try removing the fuel filter and filling it up manually then refit

I'm no mechanic but our own mechanic did it. Remove rocker cover and the round black plastic camshaft cover at front of engine. Obviously remove fan and cowling over fan. Remove one of the bolts in the end of the camshaft just to check if the bolt hole is aligned in the middle of the oval slot. Mine was way off centre. Set the camshaft in position and set with a retaining peg. Loosen other two bolts in front if camshaft slightly. Then you need to adjust under bell housing. So the round and oval holes line up on front if camshaft. I'd take it to and Indy to be fair to do this job. Only takes half an hour including stripping the rocker etc.
