%@#n it!! Car won't fire up!! I did do my time searching for the answer to my problem but I can't find anything that fits my situation. I have an 01 WS6 M6 with 30k miles. I store the car in the winter and got it out about a month ago. It started up fine when i got it out. As of lately however on some of the cold mornings it will not started. Sometimes it will crank for forever and kill battery. Other times if I keep turning the key on and off instead of holding it it will start. If it doesn't start right up then it won't start at all. I put fuel system cleaner in the last tank of gas I had hoping that would solve the problem if it was moisture. i am on another tank now and same issue. Tried to start it tonight and nothing. Pushed it outside and it started up. I put Seafoam in the tank and let it run for a few minutes and then after dinner went to go for a cruise...wouldn't start. Put it in the garage with heater on (in hopes that it is just condensation), tried to start a bunch of times and nothing (just cranks). So where do I start guys? Thanks for your help and reading this long winded post.

Thanks for responding to my post so soon. The car will sit there and crank for forever (until battery dies). Therefore I am not sure that the starter is the issue. If I had to guess I would say either fuel or spark. But where do I start? Thanks.

i have seen cars crank with sparks shooting out of the starter, and it still sounded like it was cranking properly. but if you can crank it until the battery dies that it is probably not it. also do not crank the car for too long continuously because you could burn the starter.

Going to get some starter fluid tonight and try that. I checked to see if there was fuel coming out of that schrader valve on the fuel rail and there was. Just have to get a gauge and check pressure. Now if I spray starter fluid in there and it fires...what is that telling me? Faulty injectors? I could call a tow truck and take it the shop. However if you all are patient enough I would love to fix it myself and learn something. Thanks again for all the feedback.

You need spark(at the correct time), fuel(correct pressure AND volume) and compression. If it starts when you shoot of fuel source directly into the intake you can probably rule out the spark side for now and look at fuel. If it doesn't start look at spark. Does it sound like it wants to start or do you get nothing? By the sound you can troubleshoot this problem. Is it common to ALL cylinders, a BANK of cylinders, a single cylinder or group of cylinders. You have to draw lines of demarkation then attack the things on the problem side of the line you draw. Crank sensor? Use your scan tool to look for crank pulses. No starts are a lot easier than P0300s. Don't crank and crank like you've been doing. Get an assistant to turn the key for you while you do the troubleshooting and watch the scan tool output.

i love this forum. who the heck needs a repair shop. lol. when i get home from work i will check out all of the things that you have all said. Sounds like the ignition relay is the easiest to try first? if that doesn't work i will try starter fluid to hopefully figure out if spark is an issue. i think the gas is ok because it has only been in there for a couple of weeks. however the gas prior to this tank was the crappy stuff that sat all winter. I was a schmuck and didn't fuel stabilizer it for the winter. ran that gas through and have actually probably had a few tanks since then including fuel system cleaners. alrighty, time to get back to work. i will keep posting back till issue is resolved. thanks all.

and the winner is..........ignition relay!! Thank god. That was the first thing that I checked when i got home from work as it seemed like the fastest and easiest. I switched it with the Fan 1 relay. Fired up the first time no problem. Fired up everytime after the switch. Now, if I switched the two relays, shouldn't i replace the one that was in the ignition relay originally now that it is in the fan spot? Thanks a million to all those who jumped on this thread and helped me out. Car show this weekend and i would have been pissed if i couldn't have taken the car.
