3. get a scan from a bmw-level scanner; confirm if EWS is mis-matched which will give your exact symptoms.
4. charge up the battery; a jump start will likely not be terribly helpful; you need full voltage.

when my wife's car had a bad fuel pressure regualtor situation, i eventually got it to start with about 100 seconds of cranking (10 cranks of 10 seconds); your car might have the automatic start feature which will certainly not be enough.

you can put some laquer thinner in the intake boot; as it evaporates it will become explosive that will usually run a car for 20-30 seconds if you have spark and can help figure out if lack of fuel is the problem
I would caution anyone trying to use this shoemaker fix to determine if the engine can run on lacquer thinner fumes. Lacquer thinner is highly explosive like Andrew mentioned. What Andrew fails to mention is that the MAF is either a hot wire or hot film that is heated to a high temperature which utilizes the airflow to cool the wire or film thus determining the airflow through the intake. You have an explosive mixture in the intake and when you go to start the engine the MAF hot wire or film starts to get hot to the point that it may trigger the lacquer fumes thus creating an explosion not in the engine, but in the rubber/plastic intake which can result in an underhood fire. Seen this before when people try to use starting fluid on a MAF fuel-injected engine.

To the original poster have you remove the spark plugs to determine if they are wet. You can remove one bank of plugs and if they are wet you need to remove the other bank and dry or replace all the plugs as well as dry out the cylinders. If you don't have the tools you can see if you can find a mobile mechanic if you don't want to tow the truck.

The gas is just hair over a 1/4 tank. I haven't checked the spark plugs yet because I don't have any oil to put down in the holes to get a seal so I can get compression if I flooded it. A nice gentleman gave me a few bucks to get some oil and now I'm going to walk to Walmart and get a quart. In the morning I'm going to take the spark plugs out and do what you all have suggested. Is there I may need to know or try? Thank you in advance.

I'm not sure what you are trying to accomplish with putting oil down the holes to get a seal. Oil down the spark plug holes can create a misfire condition. If you are trying to clear the cylinder of gas, just put a heavy cloth like a pair of jeans over the spark plug holes and crank the engine. The jean will catch most of the mixture that is being expelled so you are not creating a dangerous condition. I always warn people to have a fire extinguisher when they perform this procedure. I know how it feels to have a car destroyed by fire. You can see in my signature that one of my Lotus was destroyed by fire.

Good luck with the B M Trouble U

I have an old high school classmate who owns a BMW repair shop in Modesto, CA. I got in contact with him about the issue earlier today and he's the one who said once I cleared out any gas from the cylinders to put a few drops of oil because the gas will have washed the oil off the cylinder walls thus there won't be a seal for compression. It was hard enough to call him because he's a friend of my ex's. In the morning I'm going to pull the plugs and give it a go.

NO OIL!

Please, if you really want to get this thing going DO NOT put oil in the cylinders. Any damage that may have happened is already done. If it is as simple as a flooded situation and you clear it out, it will start right away and you will have plenty of oil pressure/splash. If you put oil down there, most of it will end up in the plug well/socket and make a mess!To say nothing about it causing all sorts of plug fouling that will just exacerbate the whole issue. You have all the information you need here on this forum. No need to be calling anyone unless they can come to you in person.

If you do find out that the engine is flooded once you get it started drive it to an oil change shop and have them do an oil change. The gasoline in the engine will have diluted the oil and the viscosity of the oil is no longer what BMW specified for the truck.

Make sure all the coils Paks are disconnected to eliminate any type of sparks that can ignite the mixture when you go to spin the engine to expel any gas in the cylinders

Good luck with the B M Trouble U.

She just using one of her "Lifeline" to call a friend. Nothing wrong with that especially if that friend is an ASE Certified Mechanic.

I was taught my mechanic skill by an ASE certified mechanic. My dad was a certified ASE mechanic for 35 years.

This is getting .... I don't know what... All I see when I read these posts is flames from all the fuel.

Disconnect all plugs, Lay towels over plug holes, crank engine for 8- 10 sec watch for fire. DO NOT ADD MORE LIQUID down each plug holes before spinning the engine over with the plugs removed. PLEASE

Getting the popcorn
