Help Please. Engine Management Light
« on: 02 July 2007, 20:50:23 »
Hello all

Driving home after a day out the car suddenly lost power and I noticed that the temerature gague had shot right up (normally runs about 90) and its light came on. I stopped as soon as I could and checked coolant level which was OK and no pressure in the header tank. On restarting the engine the car revved to just under 2K and dropped back down to normal idle and the engine light came on. Now it is hit or miss if the light comes on or not (more often on) and it always rev up first. Cheepo Tech 2 will not connect to ECU to read codes (2.5 TD BMW engine) but did alow me to reset airbag light. Any help greatly appreciated.

Will need to read the codes I suspect. It will need a real Tech2 as well.

Oddly enough, even when putting faults on my tractor, I can't get the EML to come on....

Sorry, a decent scanner should be able to read it. What I meant was cheapo Tech2 lead won't read it...

So try an indie....

Thanks TB Looks like it may be the fuel pump as it won't start at all now  :'(. Getting voltage to the pump but can't hear it running (not sure if I would though) and getting high resistance about .4 - .5 Meg Ohm accross the pump but again not sure again what it should be but I would have thought it would be much lower that this.

Unfortunately, probably the one person - Omegatoy -  who can help has no internet access at the moment.  I am guessing the pump won't be cheap :(
