My Mini Cooper 1.3i has been of the road for about 4 months now, I've put in a new battery, cleaned plugs and changed rotor arm dist cap but engine will not fire. I can hear the petrol pump buzzing but no sign of it firing. What would be the next thngs to check?

Thanks
Jeff

Are you sure it's an ignition problem? Or are you in a "I'll keep changing things 'till something works" mode?

First.....check to see if spark is getting to the plugs. Pull a plug, lay it against the block and have somebody crank the car over and see if it sparks. Check all of the plugs to see if they spark. If they do, you've probably got a fuel problem.

Thanks Xracer I'm going to try that 1st thing tomorrow. If I do get a decent spark from the plugs and I start looking toward the fuel what would you suggest to try 1st?

Thanks

If you do have spark, check to see if you are getting fuel to the carbs. If you are, take the tops of the float chambers off, and make sure the needles aren't stuck closed.
Or, and this can be a bit dangerous on occasion, squirt a little raw fuel into the carb throats, and see if it will start, or at least fire. Always a good idea to have a fire extinguisher handy when using this method. Ideally, in your hand at the ready position whilst someone else cranks the engine over.

Well, if you've got a fuel problem.....that is a problem. If your fuel pump is pumping, then it's something in the single-point-fuel-injection sytem, and I don't know beans about them.

Carburators are old fashioned, but at least I can fiddle with 'em.

Unless somebody here knows something about SPI, you may have to break down and take it to a mechanic.

Well I've given up, was getting a good spark and could get a healthy sound from the electronic fuel pump but it didn't start at all. Narrowed it down to an electrical prob, like an immoboliser or injection fault.
Cars gone into a MG Rover garage today my last resort. I'll let you know what the prob was and what the nice people at rover charged me!
Thanks for your help.

Good Luck! Let us know what it is.

SU's are a pain in the butt, but at least you can work on 'em!

Hmmm
The MG Rover garage rang me to today to say they can get the car to start but runs for 30 seconds but then cuts out!! They have checked the fuel injection and ignition all seemed to be fine, so they are still investigating.What do you think it could be?

The Prince of Darkness strikes again? Perhaps an electrical gremlin in the SPI unit?

.....or, I'm wondering if it could be something as simple as a clogged fuel filter....perhaps an internal one in the injection system (if they have one in there)?

I dunno.....just one the many joys of owning a Mini! images/icons/rolleyes.gif

MG Rover got back to me today to say they think the valves are sticking after the car has been left standing for a few hours. One of their senior mechanics is going to put some sort of engine treatment in and take the car home tonight to give it a run, does this sound ok to you?

Thanks

Are you talking about the engine valves sticking.....or some sort of a valve in the SPI?

Hi
They took a while but cars back now. After all the problem it was cutting out was a temperature switch in the injection system?? Cars running really well now.

Thanks for all your help again.

Well, glad your Mini is back on the road.

That's one reason I don't like SPI....too many complicated little pieces to go crump!
