Hi i have just got my hands on the above car ,i am having a lot of trouble with it.every time i take it for a run as i slow down i loose all electrics and the cars cuts out.Will restart after5 -10 minutes but may cut out again very quickly. Help please does any one have any ideas as to the fault as i thought that i might be able to get from a to b quickly in this car but the fastest it has been is on a towbar behind an rac van

thanks

Where abouts are you? Anywhere near Brackley?

thanks for the quick reply,do you have any idea about what times to change this and a cost involved would like to travel to the westcountry tomorrow as i didnt make it today.even though i have only had the car for 5 days and despite the trouble with it i do not want to send back to dealer as when it is going i love the thing

Before changing the part, it may be worth connecting up to some diagnostic equipment to see if a fault code is stored. Part is around £60 and is fairly easy to fit...

sory forgot to let you know where i live eastleigh in hampshire

A bit far from me to come out help

As I said, see if you can find someone who can read the fault codes...

Just to add tht I have a 2001 2.6 V6 Auto for the past 5 years and it is a fine car indeed.... suggest you try to hold on to it and get the problem sorted with some help from the wise ones (not me) here.

? He's loosing all electrics. Would that happen with crank sensor or is it likely to be a bad engine earth?

something to say our Kev ? Cat got your tongue ?

needs fault codes from facelift before we can really diagnose, i wasnt sure about electrice and crank sensor myself.....but i kow as much about electrics as my wife knows about budgeting.

Don't fancy losing any body parts Mark.

All i will say is, I agree with you, more accurate information will be required, starting with a list of stored DTC's, if there are any, before a correct diagnosis can be made.

You'll have noticed the 'I bet' is completely missing from this post.

the garage now seem to think that the fuel injection relay needs to be replaced unfortunately part is not available until monday,will let you know the result

You say you loose ALL ELECTRICS. Is everything dead at this time, no dashboard lights, no radio no door lights etc? And what happens in the 5 to 10 minutes that it won't start, is it the same or does it turn over.

If it really is loosing all electrics you will be replacing everything and still not find the problem.

jarb · « **Reply #14 on:** 30 September 2006, 15:34:56 »

sorry car is in the garage at present,dont mind at all because it aint costing me a penny still want the problem sorted though.

when it cuts out i loose everything lights radio power steering ect once i turn the key the motor turns over but wont start even though all electrics are working again.like i said then if you give it 5-10minutes it will start again

That rules out your CrankShaft sensor then. If that goes only the engine will fail, not the entire electrical system.

Does sound more like an earth fault that is causing the problem.

rpont · « **Reply #16 on:** 30 September 2006, 16:36:17 »

I'd check the earth cables then. There are two from the battery. One goes to the air conditioning compressor bracket, at least on mine and the other, thinner one, goes to the body just below the battery tray. For the starter motor to turn you have a connection to the one going to the engine and if it was that one I would expect the radio to still work but you say you have the electrics back by then and it just doesn't start for another few minutes but I'm not sure how the ecu and immobiliser are involved in turning the engine over.

I'd be seriously looking at both ends of both cables for security. It may be that when things are warm the bolt expands just enough to break the contact slightly so that you aren't getting enough current for the electrics. I've also seen a battery where one of the posts came loose internally and that could cause your starting problems but I don't know if it would cause the engine to stop once it was running, I wouldn't expect the electronics in the alternator to be that sophisticated. If the cables are secure I'd get the garage to try another battery just to eliminate it, and they must have one they can try without selling it to you.

If it wasn't for you loosing the electrics it's a classic crankshaft sensor fault though :-)

thanks for the idea garage reckons they have checked the earth, also has beenplugged into a comp and ecu comes back no fault found, will the ecu pick up the crank sendor

Yes, the ECU would record a DTC for the crankshaft sensor, but not necessarily for an earth/wiring fault. Have all battery/earth connections been checked, and i mean properly?

A crankshaft sensor would not cause you to lose all electrical systems, it would only kill the engine. The ECU would register a fault with the sensor, store a DTC and shut the fuel and ignition systems off for protection, all other electrical systems would remain unaffected.

rpont · « **Reply #19 on:** 30 September 2006, 21:10:44 »

If the ecu had power when the crank sensor failed I would expect it to be logged.

I don't know what's usual with earths. I think it used to go to the engine and then from the engine to the chassis, I'm thinking back to the x's Escort here. There are several earth wires connecting to the earth point below the battery tray and it's not really visible unless they know to look for it. The battery that had the loose post was in a Chrysler Grand Voyager and the guys garage was puzzled by the fault but the post turned fairly easily when I twisted it. He had all sorts of intermittent problems but I just can't remember whether it cut out on him when it was running.

Ahh, missed bit about all electrics going. That wont be crank sensor (which would be stored as a fault code).

Earths, possibly a regulator problem?

Nearly lost something there.
