Bmw Starting Problem - BMW Forum

quasio · 02-17-2009, 04:04 AM

I have a 1984 318i BMW. I was driving down the freeway and all of the sudden it was like somebody flicked a kill switch. I could restart it for about a minute and after that it would not start at all. It would try to start and then just turn over. I thought it was the Water temperature sensor? I also changed a few relay's. my fuel pressure is 47 psi and when turn off it holds at 45 psi. I have had my car to a few shops and they couldn't figure it out. I changed the fuel filters. Can somebody please help me out on this one. It has me and others stummped.

I had changed the whole unit with another and still the same thing. Would some w-d 40 work on it? I am not sure I am not a mechanic.

After loads of thought..............the ignition switch.

Would that be ignition were the key goes in? If that is what you are saying 2 weeks ago I was thinking that same thing. Because what had happened was, once thae damn thing started and it ran for 2 hours. Then I turned it off thinking it was OK, not even 3 min I tried to start it and it just kept turning over. i herad a little click from under the steering colum and it did not start. So the Ignition or are you meaning something with in the path.

I think by ignition switch he means the actual electric contacts in the key cylinder assembly. So, an intermittent electrical contact issue in or around that cylinder.

Thank you. I wonder if that would explain why my battery is always going dead. When I fully charge it I connect it try to start the car and if I leave it connected overnight is is always dead by morning. Ignition would it keep a open drawl like that?

However thaey had the damn thing running for a couple of hours. Then next morning they tried to start it no go. Question would the catalyst converter have anything to do with all this? And my battery is still going dead by morning. still wont start can some one if you have any type of info plkease let me know
