Not sure what fuel pump the cars running mate, i didnt do the conversion myself so i'll ask the bloke that did it?
Took the car for a drive today and got it roasting hot and the fault seemed to dissapear! however the car hadnt been started for about a week and when i went to it this morning it really struggled to start and took a couple of turns, when it did start it idled like crap for about 2 minutes and when revved it shuddered badly and cut out but the restarted first turn with no problems
also when i've looked under the bonnet the lambda sensor isnt connected up, could this be the cause of the problem? It also seems to run very rich and have sh1t mpg!
