2003 BMW X5 4.4 Crank but no start

[Mizzroxy69]

I took the driver door panel off to fix the handle on the outside. It wouldn't open anymore. After it was put back together I started it and moved it 3ft to close the garage door. Next morning it cranked but wouldn't start. Fuel pump is running. Changed the camshaft sensor. It's trying to get gas but not enough to fire over. Any suggestions? Fuel filter perhaps?

Hey,
Spinning well with no firing? Spinning well with sporadic firing? Spinning so so with no firing at all?


Bad ignition switch will let the starter spin,but engine would not fire.
Bad fuel pump relay will cause sporadic firing,but no start. Even though the pump is working.
The last one would be obvious like low battery juice.

I would say that you flooded the engine when you started the truck moved it 3' and then shut it off.

Put it in clear flood mode by pushing the accelerator all the way to the floor and cranking it until she starts.

No I didn't flood it. I turned the key over like I always do and never touch the gas pedal. I'm waiting to get paid to buy another battery. Even though the date on this one is 2/20. The person I bought the car from didn't leave any paperwork for it. If the new battery doesn't work, then I'm going to replace the fuel filter.

Congrats you are my 7000 posts on this forum. Someone offer to help you with your problem and even give you the solution on how to fix your problem and instead of being grateful you prefer to argue with them. Good luck fixing your X. I’m out of here.

He answered you that he didn't flood it and explained how he tried to start the car and the steps he used. He didn't not "argue" with you.

Read up on how easy it is to flood a BMW by just starting it up and moving it just a couple of feet or into the garage and shutting the engine off. The engine is in open loop when you start it so it is using a set of pre-map values for things like injection duration. A cold engine needs more gas to start and run during the winter months. Prior to electronic fuel injection, this was accomplished with a choke which restricts the amount of air thus creating a richer mixture. Fuel injection accomplishes this by changing the injectors pulse duration thus injecting more gas in with the air. His mistake was not letting the engine warm-up so that it would go into close-loop so the computer can control the injector pulse duration base on O2 sensor reading. Are you still with me or is this getting to technical for you?

Instead of saying he will try the solution I gave him he said NO he didn’t flood the engine.

This is my 7001 posts. Unlike you most of my post offer solution to problems

Maybe you should just stick with posting about Saudi Road Pics or in the Politics Forum

Since the battery is less than a year old and is now dead, I would say you killed the battery by trying to crank the engine. Just charge the battery. You did more damage by cranking the engine and not using my suggestion to clear it in clear flood mode. Every time you tried to start the engine in non clear flood mode you added more gas into the cylinders. The plugs are now soaking wet but you have washed the cylinder down with gas maybe up to the point that you have reduced the compression in the cylinders. You will need to remove all the plugs and either dry them out with compress air or replace them with new plugs. While the plugs are out you can use the starter to spin the engine to expel any gas in the cylinders. Just remember that you are pumping out an explosive mixture and can be ignited very easily. If you are not sure as to how to perform this safely I would suggest you have the X towed to a garage with a mechanic that knows what he is doing.

My reply is "Bugger Off"

if you are not familiar with that term, here's a video.
