cutting out whilst driving??

[benji78]

just been for a blast in my tech 2 sport and it cut out at 90, turned it off and then back on again and it was fine, its done it several times tonite normally under heavy accerlertion? any ideas why its doing it.

Probably just doesn't like being abused

Splutterd and died or just died ?

[benji78]

cut out dead, turn it off whilst coastin and then back on and then off it goes.

Rough guess, Possible fuel pump on the way out or an ignition relay.

Or the rev limiter

[benji78]

its not the pump cuz thats brand new, and it defo wasnt the limiter, i no i was driving it hard but not that hard, where would i find said relay? is under the column or behind the glove box?

[Martinaston]

Next to the air flow meter.

Check the connection on the fuelpump too, mine was bad and caused strange cutouts, ended up replacing it with a 25A choccyblock, sorted!

[cliffybabe]

check the IC boot and ICV, had loads of issue with this recently when i gave it some beans

[benji78]

rite ive just checked the ic boot and the icv and they seem to be fine, next i checked the fuel pump connections and they were fine so i changed the ignition relay for 1 of my mates sport. took it down the road and it done exactly the same!! annoyed and confused so any ideas??

[kam-325i]

The loss of one of two things will cause the engine to cut out, Ignition/Spark and Fuel/Air.

If the fuel is ok, then start to look at the ignition system.
What engine is it? M20B25 ?

Fuel pump relay ?

Orange one next to the white (DME) relay under the bonnet.

dont mean to sound a know-it all, but scrap ALL of the above and go straight for your ECU!!!! Open it up and i bet you that you will find you ecu either sitting in a bath of water, or with completely corroded electrical tracks. what you describe is the exact and i mean the EXACT same thing i had with the car in my sig pic when i used to own here. If its an 073 ecu, ihave one here you could try in its place.

[benji78]

scotty mate ur spot on, opened up the ecu and the tracks have corroded like fcuk, wud the one of my 320i cab fit?

[SCOTT325SE]

Glad to be of some help! The one on your 320 would not fit unfortunately. Take a look at the stickers on the ECU casing. You will probably have a number that ends in 073 or 064.
You will need an ECU with a number that matches your existing one.

If it happens to be an 073 ECU, i have one here as I said before. If its an 064 one, its running slightly different engine management, so you will have to get one that matches that.

If i can help any more, please let me know.
