PLEASE HELP ME - Cant start my 540i
Hi Guys I really need your help in diagnosing the problem with my 94 540i.
For the past 2days my car with crank up but just wouldnt kick in and start after the car has been sitting for several hours (such as in the mornings or whenever parked for a long time).
Yesterday i finally got it to start after and in like 2mins into warming up it just shut down. This happened about 4 times. I did an error code check and came up with 1444 meaning no error codes. last night I change the old bosch plat 4+ plugs back to new original oem plugs and the idle seemed a bit smoother. I added a 20oz bottle of Techron fuel system cleaner as i filled up with gas and all night the car started and drove great without any problem however this morning it would not start again. I came home at 2pm from work and the car starts without a problem and warmed up fine. I shut it of and tried several times and each time it started without any hesitation.
I dont know what else to do? What could be the problem? Please help I need the car to go to work and it seems like it hates starting up when the weather is cold. Any ideas???
