Hello,
A friends 98 mpi cooper wont start. I've no experience with injected minis but gather the diagnostic port is the place where the answers can be found!
I'm going to have a look at it tomorrow to check the obvisious things, but I know the battery is good and the fuel pump can be heard when the key is turned.
I'm not convinced the immobiliser fully working - is there a way of bypassing it to see if the fault lies there?
Failing that.....
Before she sends it away on a tow truck have any of you got the diagnostic machine that might point us in the right direction?
If not any garage reccomendations in Hastings that can diagnose the problem?
Stu (on behalf of Lucy and Lola!)

If the immobiliser were on it wouldn't turn over

Went back today-just as it started pouring down again!
Looking at it closer the red LED in the dash does go out, and a click can be heard behind the dash (and I managed to set the alarm off trying the key in the ignition) so I guess it is functioning.

there is only a few people on here that know about mpi/ spi engine.
so i would not have a clue, check the fuses???
most of us know about carb minis
there are members of the club with a code reader. but i leave it to them to post
good luck i how you get it running

Should be able to hear the fuel pump energise when the ignition is put on . Get someone to turn ignition on while you have head in the boot . At least you know that is working.
These are quite good for the coolant temperature sensor to pack up .
It senses coolant temperature - if ecu senses coolant is cold like it would be first thing in the morning the ecu will put the choke on to put it basically . When it senses coolant is at correct temp it will reduce it .
The rad fan running when the engine is not really hot enough to warrant it being on is a good indication the sensor is wrong . It can think the coolant is hotter than it really and put the fan on to cool it down .
Best get someone to look at it once you have covered the basics , fuel , spark , feed to starter , earhs etc.

Fuses are good.
The fuel pump energises when the ignition is turned.
Then the dash lights all illuminate but it fails to crank.
Looks like a trip to Skinners is called for then unless anyone knows if Gerald Dale has a diagnostic?

....if it fails to crank it is still immobilised. As I've said three times now!!  Change the keyfob battery and try that |

Stephen, bought a new battery and changed it today- it still does not crank. The immobiliser/alarm light is the one that I was refering to in reply 2.
I'm guessing the immobiliser isnt t he only thing that will prevent it from cranking...
anyhow she is going to take it to a garage tomorrow

Why not try bump starting if all the dash lights light up (indicating ignition circuits on)  Could be a faulty starter motor  Alternativly have you looked at the earth for the starter solinoid... if you have one on an MPI that is N. |

Reading that reply no2 that click could be the starter solinoid turning over... but the starter moror could be jammed. this happend to me a few times in which case try rocking it backwards and forwards in 1st or reverse to free it off.
By the way take my advice with a pinch of salt as I could be leading you on a wild goose chase as I'm no expert.
Good luck

Any contributions are welcome! As I've said its a friends car and I was just trying to help her out, but I know nothing about injected minis....
It no doubt will be something really simple but she needs it back on the road so is going to get it recovered to a garage.
I did think about a bump start but she lives at the top of a hill on a road where parking is limited and we figured if it doesn't start we'd be stuck!
Thanks anyways, I'll let you know the diagnosis when(/if) she gets it sorted.

Has it got feed to the starter ?

Yea grab a multimeter and check to see if live at solenoid / starter as Dave says.
If the clicking is under the bonnet rather than behind the dash it could well be the solenoid. Or else my next step would be to check all the earths. If the battery is good but it's not cranking then often it can be a poor earth, either in the boot or up front.
Failing that, get it over to a Gerald's. It can be very difficult to diagnose a problem on a forum.
