Doc, the way you explained it your engine is turning over just fine. If a battery has the power to swing the engine over for a period of time then it has the energy to power everything else. Battery should be fine but it doesnt mean the supply to the fuel pupm is necessarily fine. Go with the filter change anyway as it cant do any harm. Then start looking at the fuel pump.(It could even be the power supply to the pump) Just my opinion. Good luck and let us know.

i doubt it's the battery or fuses

IIRC the ignition on the car is not fused. the fuel pump could be the culprit but i doubt playing with a fuse would change it.

and if there's enough juice in the battery to turn the engine over, there's definitely enough juice to give it spark. turning the engine over requires lots of current.

although trouble shooting modern engines is a lot more difficult, you need to start with the basics. when the problem occurs, do you have spark? do you have gas (getting to the cylinders)? very often, one of those two are missing.

Mine ocassinly doesn't start after being warm, but it is less frequent now. I just turn the key to on for a couple of seconds then it always starts up. The reason I said start with the fuel filter is there is a pressure regulator bulit in to the fuel filter and it send fuel back to the tank if the gas can't pass though the filter, ie junk in you fuel or sedment that got moving around. If it doesn't start the first time I turn it off, then to the on position for 2-3 seconds and let the fuel system pressurize it's self again.

This just happened to me. I can't believe it. Could it be a battery problem? Mine x5 is less than 3 years old. When I start it, the light flashes on and I hear a beep somewhere in the engine compartment. I don't hear any cranking. In fact, I don't think it's cranking at all.

The clock is blanked out. So, we lost the battery at some moment prior. After few attempt to start it, I can no longer lock the door with the key anymore. Does this make any sense?

After jump started it, I brought it home. I'm scheduling a service at the dealership. It's under 4 year 60K warranty, how much can they charge for diagnostic services?

A new batt will quickly tell the tale, imo...
There is considerable debate as to whether any
Stlr will R&R your oem batt, "for free"; it varies
considerably from dlr to dlr based on posts here.

A new, well charged batt. should cure your ills; if
it does not, then digging/diagnosing is more focused.

Heat and never being slowly & fully charged, is really
the enemy of most car batts.
