what fuel pump are you using ?

[partytownsri]

1400sri one

[coombsey]

is that single point or multi because my redtop wont run properly either wont start and when it does sounds like it is missing and wont rev up only revs up some times

Have you changed any parts like cambelt etc? before it was fitted.

Have you heard it run before fitting it?

try cleaning the injectors as mine was the same and it turn out to be the problem

[partytownsri]

ive check the management light but nothing, ive cleaned the injectors, it ticks over tiny bit lumpy just under 1000 revs but when i rev to about 3500 and let off it back fires and gives a little bit of smoke, could it be because its got forged pistons that raise the comp to 12:5-1
