Car wont start, Help

[toohotdoc]

Well i need some help, my X5 wont start AGAIN. So almost every morning(every odd day) since last 2 weeks it doesnt want to start. The car just turns over and over but wont start. I play with the fuse box in the glove box and take some out to check them and put them back in and boom it will start out of the blue, sometimes taking a minute or two. I realized it doesnt matter what fuse is out as i thought it must be related to a specific fuse but all are good. After it does start, the start up doesnt sound the same as before, the timing sounds off everytime i start the car. It will start after this all day but then next morning is ? again. Anyone have had this problem or solutions to it? I cant deal with playing with fuses to start a freekin vehicle! I dont even know if thats the problem!

Never had that occur! Recommend that you have it checked out by the dealer.

How old is your battery? That would be the first thing I would check. The X needs a lot of juice and it needs a battery in perfect condition.

The fact that the X will start the rest of the day but not the next morning makes me really think that the battery must be the issue here.

Well i will try a jump when it happens again. I just dont see why the battery would be the problem because this only occurs sometimes and always in the mornings. I can leave my stereo on and lights on for a good 30 minutes and still starts without hesitation and i am running a 1000watt amp and sub. When it doesnt start the lights are fully lit and the xenons also turn on. Could it still be the battery with me doing all this to check?

check battery and alternator. weak battery and bad alternator can cause cylinders misfire (1 to 6) it then cause the starting problems. best thing to do is to have the battery, alternator and start checked out. cyclinders misfires can cause things like rought idling, timing, unstabling reving. but you say it doesn't start on first try in the morning, that seems like battery is on its way out. search for my posts on battery and alternator replacement posted sometimes ago.

The car wont start in the mornings for numerous amount of tries. I have checked the fuses and by taking some out and putting them back in seems to start the vehicle. I cant figure out what fuse because everytime its different, i think that it must be one of the fuses and takes time to reset and then it starts but i am not sure of this. After playing around with fuses and trying to start the car numerous times it fires up out of the blue. I dont see how a dead battery will let starter fire repeatly ( i have to turn the key back to stop the starter) and wont let it turn over to start. Not a mechanic by no means, but can a battery have enough juice to let the starter fire repeatedly without turning over to start?

I had a very similiar problem occur, the sedement in the tank would cause the fuel filter to send the fuel back to the tank. Try changing your fuel filter and it would hurt to check the pressure of the fuel pump. I believe it's around 50 psi or so, most garages can help you change it and check the pressure.

Most likely you are giving the fuel pump a nudge by removing the relevant fuse and this will temporarily clear the blockage. The "off timing" noise would then also make sense as the motor starts up after fuel starvation.
Hope you get it right!

so the battery is out of question? I guess i should take a shot at changing the fuel filter.
