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

may be an issue with the "fuseable links" by the battery overheating?

how about connecting a voltmeter to the underside of the relay pins to see if the ECU feed disappears when the engine stops?

I presume the sensors have been checked, by substitution if necessary?

The cars runnin a motorsport loom so takes its power direct from the bat, so i was thinkin the only power the ecu takes from the fuse box would b igniton live by any chance do u know what relays i would need 2 check,

think this weekend we will b swapin sensers over, i 4 got 2 add in the original post we did actually try n gi the car some throttle when it started, but this just killed the engine, so any chance it could b a faulty throttle position sensor?

check the voltage at the engine loom relays

if the ECU is still taking 12V through the ignition, it'll still be using one of the fuseable links - just unwrap the wiring near the battery and inspect the joins of the fuseable links to the "normal" wires
