Can Anyone Help!

hi guys,

Ive got a problem, took my car into a workshop to dyno and fix some fuel mixtures and when i went to pick it up they couldnt start the car.

So if you keep cranking the car over it finally starts and runs then if you turn it off it wont start again you have to keep turning it over.

It has good spark,all fuses are good alarm disarmed,

They said the injectors pulse is very weak or something like that???

could it be a fuel pump???

Try a different crank angle sensor. I had the same problem couple years ago had good spark but the injector pulse looked weak this was tested with a noid light.. I spent days trying to figure out the problem not concerned with the CAS because i had some pulse from the injectors with great spark.. I changed out the CAS to eliminate almost everything on the car and it instantly fired up and ran as normal.... Hope its something simple and remember rb20 silver top uses the same CAS...

if u got spark then it either a fuel or electrical . CAS or ecu would be 2 things to look at, my car got a real dodgy tune and that has cause me all sorts of problems like it starts sometimes but then idles like a dog and misses or it runs like normal on the odd occasion. these things are a bastard to find so happy hunting
