Topic: Non-start ..the saga continues! Posted: 22-October-2005 at 08:13 |
Hello everyone, The continuing story of my non-starting 1985 635 continues. More money spent, no more joy. The sensors that many people have told me about have been changed, the 2 that connect to the flywheel. These are now brand new, and returning perfect resistances - but the car still wont work, and I still have no spark. Here is a list of everything that I can think of that may point to an answer... 1. Everything after the coil, including the coil is fine, so it's something pre-coil. 2. DME realy, and all relays and fuses in fact are A-OK. 3. ECU's seem to be OK, as there are no visible blows on the componentry. 4. Fuel is OK.
It just turns and turns and turns and will not fire (as I said there is no spark) Things it could feasibly be, which I hope it is not..
1. ECU 2. Some blow in a wire or connection somewhere. 3. Something to do with the new SI board that was fitted about 6 months ago - but was running fine with for 3-4 months. The only thing I have not replaced sensor wise is the one at the front, which connects to the crank, which is absent on the earlier cars, but is on mine (has the same 3 pin connection as the other 2). Apart from that I'm stuffed - I have nothing else to go on. It was running fine, and then all of a sudden nothing at all. The only thing that happened was that the bonnet slammed down as my struts are all weak, but I cant think that had anything to do with it. And im not even sure that that that occured before it wouldnt start. ...Any suggestions from anyone? (I will be annoying some of you about it this Sunday, so hopefully see some of you there. -Ben

Don't know where you're going this Sunday (and I don't know how easy it is to remove install the ECU), but you might want to take it along and see if anyone will install and test it for you????!? Would make the fix a little easier if you eliminate this. |

He'll be at the Donington Park BMW show. Which is where a number of us are also likely to be.....

Thats a good idea Paul (and one I thought of) but there is a possibility that fiddling about with someones car while they are away from home could also immobilise their car and induce a very bad day for them! The ECU's are to the lower right of the steering wheel, mounted in the bottom of the dashboard - and some of the lower dashboard pannelling has to come off! Easy to get at, but its not a good idea to do away from home. -Ben Edited by phb10186 |

I,m no mechanic so excuse my ignorance, but earlier you spoke of " ripping out an alarm " & having read what you have checked & replaced with very little improvement it may be prudent to check that all immobilisers have been disabled???? Once again this is about as educated a guess I can give for a suggestion. Good luck, we are all willing this six to start. |

A long shot. Did anyone mess around with the OBC 'immobiliser' code?

right, just a long shot here. is there a dme relay as fitted to the e23 on the offside turret suspention turret. its a fuel relay that often go same type of problem. i thinks its this. its either a silver one or white. if you take the fuel pipe off the fuel rail then crank over the engine and theres no fuel comming out thats your problem... the dme relay is just on your drivers side bulkhead. more likly this has packed up.

is the coil defo getting power? a non-starting golf of mine was cured with a new ignition switch. I forget which but one terminal should get a constant 12v (not the big chunky HT terminal obviously but one of the other two) excuse me if I'm re-covering old ground but I'm new to the saga. Whereabouts in N London are you? I'm in Marylebone but I have no brakes to speak of!! |

We really should turn this into a West End musical - I can see it now.... "C'mon Baby Light My Fire" - the story of one man's futile effort to start a car. Starring Ben Marks as himself, Jackie Mason as Mr. Marks, Julie Burchill as Mrs. Marks, George Galloway MP as Ross Harris......and a cast of thousands

The ruddy thing turns over fine, it cant be the ignition switch. I dont get power to the coil, but everything after it is OK. Ultimately there is no spark.

-I thought the coil was switched low- if so then you have a simple feed problem if you never read 12V on it... -just a thought.... cheers

One other thought. Is there an imobiliser / Alarm in your car tht you don't know about as this could be the source of your problems. I had a problem once fairly similar to this where there was no spark and it turned out to be the imobiliser that the insurance company insisted i have fitted in the car. A RRPITA I can tell you. Good luck and keep us posted on the saga. James |

Well this is a massive RRPITA too, more of a RRPITFA to be honest.

Before we go barking up the wrong tree again, please note that the only other immobiliser other than the TOAD alarm which Ben had fitted is the BMW "code"-armed one, operated via the OBC keypad. However, disconnecting the battery cancels it, as everyone knows. Ben's disconnected his battery more times in the past fortnight than you've had hot dinners, so I'd hardly think the BMW immobiliser is still running. |
