Car Forum / MINI / February 2004managment systems?
I have a k reg mini cooper, single point injection. my car wont start. theres loads of power from the battery, so i thought its not sparking. I got a new dist cap and rotor arm. no change. new plugs. same. i checked if petrol was getting to the injection system, thats running fine. i have checked all fuses. The only thing left is the managment systems? have i missed something? help me!!! Please!!! cheers kris (UK, essex) ____________________________________________________________ email me: kris@flamingeight.co.uk www.flamingeight.co.uk There is a white wire going to the fuse box on the right, this always caused the engine to die when it was pulled or played with! In the end it was a connector or in line fuse that had corroded.

If yours wont start or run full stop then it prob should. It maybe trying to start with no choke, tested the temperature sensing circuit? chris I have a k reg mini cooper, single point injection. my car wont start. theres loads of power from the battery, so i thought its not sparking.

First chant the mantra to yourself. Compression Ignition Fuel Compression: As usual, unless something catastrophic has gone CRUNCH!, it's unlikely yo've lost compression overnight. I'm assuming the motor is not almost worn out. Ignition: > theres loads of power from the battery, so i thought its not sparking. > I got a new dist cap and rotor arm. no change. new plugs. same. Have you pulled out one of the plugs and checked to see if you are actually getting a spark at the plug gap? Once again, if you have spark and you haven't been interfering with anything, it is unlikely that the ignition timing has moved or anything (but don't assume it hasn't if you go through everything else and still haven't found the problem). So, confirm you;ve got spark and that none of the plugs are fouled. Again, a single fouled plug is not going to stop the car starting. > i checked if petrol was getting to the injection system, thats running > fine. Do you know if you are getting fuel into the combustion chamber? Do the fuel injectors click? If you remove the spark plugs, Are the spark plugs damp with fuel? Does the air pumped out as you turn the motor over smell of fuel? > i have checked all fuses. The only thing left is the managment > systems? have i missed something? The management system is a central computer, which very rarely fails, and a whole lot of sensors and outputs, each of which produces characteristic effects if it fails. And if you can get hold of the diagnostic procedure, the computer will even tell you whathas failed and in what way. Unfortunately, I have never yet seen anyone post here that they have access to the procedure, which is a pity, since it usually only occupies a few pages of the manual and is pretty straightforward. Check your ignition and fuel and get back to us when you've decided which is not working. Graham in Oz. cheers for the info. my car does start now but its temperamental. I am getting sparks from the plugs. the plugs are not damp with fuel. when I start the engine and give it gas, I can smell petrol. (that's ok right?) I started the car yesterday and drove around the corner and it conked out while I was driving, and I couldn't start it again. (my dad toed me home, DOH!) then today I looked inside took off the injection top. checked the looms either side for damage, they looked fine. put every thing back on, tried it again, vroom! first time. I really did nothing. its doing my head in! Minis! who'd have 'em? cheers Kris > > Kris Kirven wrote: > [quoted text clipped - 52 lines] > > Graham in Oz. > my car does start now but its temperamental. > I am getting sparks from the plugs. > the plugs are not damp with fuel. > when I start the engine and give it gas, I can smell petrol. (that's ok > right?) OK, you have fuel AND spark, so now we're getting somewhere. I think you said you'd replaced the cap and leads earlier? Anyway they typically result in missing under load, rather than the sorts of things you're describing. What is more likely is that the input from one of the many sensors is not correct, so the engine management system is providning outputs which are not appropriate. A classic example is if the temperature sensor goes on the blink and the system runs rich all the time because it thinks the motor is cold. > I started the car yesterday and drove around the corner and it conked > out while I was driving, and I couldn't start it again. (my dad toed > me home, DOH!) then today I looked inside took off the injection top. Injection top?? What do you mean? Note that I said "the input from one of the sensors is not correct" and not "one of the sensors is faulty". The sensors are designed to last the life of the vehicle so they're usually pretty robust. Often what looks like a faulty sensor is in fact a corroded or loose connector. So when faced with a mystery injection problem ... > checked the looms either side for damage, they looked fine. put every > thing back on, tried it again, vroom! first time. I really did nothing. ... there's a lot to be said for firmly wiggling every electrical connection you can find in the engine bay. > its doing my head in! Keep your fingers crossed, but it's entirely possible you've fixed the problem. > Minis! who'd have 'em? Lucas electrics were bad enough, never mind Lucas electronic injection! Seriously though, if the problem hasn't gone away, and if we don;t have the full diagnostic procedure, try to figure out when the car runs right and when it runs bad, this will give some clues about which sensors might be on the blink. > Lucas electrics were bad enough, never mind Lucas electronic injection!

Hi an earlier post by Jono Barspeed suggested a faulty wire, ??? He could be right !! I had a similar fault with a single point some time ago, turned out to be the fuel pump fuse connections inside the fusebox corroded, it kept knocking out the fuel pump,, moved a few wires and it ran ok,, go over a bump and it ran lumpy and crap, or cut out completely, Fitzy hello i run some injector cleaner through it. some sh.t came out of the exhaust. i have never changed the filter, thats next on my agenda. the car has done 70k. i line in stanford le hope in essex. near basildon. cheers kris "chris" <karen.christiaan@PANTSbtinternet.com> wrote in message news:c0oriv$1gf$1@sparta.btinternet.com... could be, how many miles does your car have?
