It wont start UNLESS I--- hold the main relay contacts OPEN for a second(with a matchstick) while engine cranks. Then, while engine is cranking I pull out the matchstick, the contacts close and it starts right up. (I took the top of the relay to do this.) Normally the contacts close as soon as ignition goes on, I think. But, what the car is doing for that second while its cranking over and the relay is open i cant figure. Dont ask how i figured out how to start it this way, it was some kind of [EMAIL PROTECTED] I tried replacing all the relays and have confirmed my relays are working by putting them in another car, which starts right up. -relays good -cold start injector works nice -battery strong -no trouble lights on in dash -starts and runs fine if I just hold those contacts open for a second while starting. apologies for cross posts or double posts, newbie ------------------------------ Date: Fri, 12 Jan 2007 22:50:44 -0800 (PST) From: Brian Ruiz <[EMAIL PROTECTED]> To: UUC Digest <[email protected]> Subject: Re: E30 1987 325 weirdness-no start Message-ID: <[EMAIL PROTECTED]> Yes, I have to say I never have heard that specific situation before. I'd have to guess it's something with the fuel while cranking that is going wacky. Like some sort of fuel pump/fuel pressure issue, OR cam sensor? Just a couple thoughts.

I did try disconnecting cold start injector tho, no difference. also tried differentt ECU same thing,tried grounding pin 86 on Main Relay, nothing. I think I can smell gas if I crank it too long without doing my little trick to start it. What is the main relay powering when it goes on? What is it NOT powering when I hold it open for a second? Oh man, hour after hour goes by, trying this, trying that. Which sensors can I try to fool instead of the main relay? arrgghhh best Egards and thanks for any more suggestions any one can come up with. > Sounds familiar. Perhaps an added valve in a small coolant line. > Valve is wired in with the coolant temp sensor. As valve degrades, > temp sensor signal to ECU goes bonkers.

Roughly 50:50 is good for 0F. At full strength, you don't have to worry until -60F. If it ever got that cold in the Tri-valley, I'd think there would be bigger things to worry about than a frozen windshield wash system. It can also be used in other ways: http://video.google.com/videoplay?docid=-699057137694538363 Of course, outside of a few selected counties, the State of Kali- fornia says one must not go beyond 1:10 and exceed 9% VOC. I don't think the other use depicted in the video would be approved either... Hey, you asked! Herman ------------------------------ End of [bmwuucdigest] digest(5 messages) **********
