Any Ideas are welcome.
Went out yesterday and it won't start. Worked fine the day before.
It is in Park and turns over great. Battery not dead yet.
No power going through fuel pump fuse but can be by passed and can hear pump kick in. No Spark when I removed Plug.
Comes up Check Control and Trans Program:
Their isnt an OBD 1 Code reader. To access to on board code system you need to perform the "stop test". This will flash the check light in a sequence sort of like morse code and you obtain the four digit code from that. Their are excellent video's of how to do it on youtube. Basically its turning the key to position #2, then stomping down on the gas pedal (all the way to the floor) 5 times in 5 seconds.
Tried that and no 4 digit codes, just check control and trans program.
Could the check control module prevent it from starting? Checked for power at igntion and no power at blue\white wire which I traced back to check control module.
Thanx for your input. After tearing everything apart found problem. It was the main relay. BMW wanted $40 for it and managed to find one in wreckers for $2. Also found a place in the states that sells parts for bmw's for alot cheaper if willing to wait a week. I will be getting another relay jusst in case cost $15. Don't know why bmw dealerships have such a huge mark up. www.autausaz.com
