Right really really stuck need some help, have been workin on a m8s (Mr C)
After a lenghty build last sunday was going 2 b the first time the car was run after checkin n double checkin everythin we started the car everythin was fine for bout the first 10 seconds then it just cut out,

Thinkin it was just cause the engine hadnt been started 4 ages we tryd again,
but every time the car kept cuttin out,

So has any1 got any ideas what it could b? the cars been converted 2 closed loop n waisted spark, we know that its not the ecu cause it the ecu out of my car, dont think its a fuelin issue cause the car doesnt splutted n cut out like its out of fuel, it just dies?

Any suggestions welcome or any ideas of test we can so 2 work out what the fooks going on
