Upallnight is right about his 7000th post. He gave a valuable suggestion which the OP didn’t respond to. We don’t know if the OP actually tried his suggestion or not, instead the OP argued with him and did not think he flooded his own engine.

Here's a good read on a no-start condition and the original owner couldn't believe he flooded the engine, even lied about the repairs suggested to him. The posts after this should also be read since it will point out that there are a lot of Cliff Claven on this forum and the internet.

Well I bought a new battery and I tried Upallnight's suggestion and it still isn't starting. By the way I'm a she and not a he. Now maybe I'm being a smartass. Look I've been living in this car since it first broke down right before Christmas.So forgive me if I'm not eloquent with my response.

By the way my engine is the M62.

I remember my old E30 doing something similar. Cranks ok but refuses to start. Apparently no fuel was getting into the engine. The mechanic replaced the fuel filter and that solved it.

Not sure if you have the same problem. But have you eliminated it as a cause yet?

Night, I get so frustrated with this exact same issue on here and other forums. These "twatwaffles" come looking for help, people with years of experience explain the solution and than it gets rebuffed or ignored! Sometimes I go off like you did. Just my needless 2 cents..

Did you remove all the plug and dried them
off and spun the engine to expel the gasoline in the cylinder or just use the clear flood mode? Like I explained running the battery down and not using the clear flood mode just created a bigger problem. If you don’t know what you are doing I already suggested you have the truck towed to a mechanic that do know what they are doing.

What does the fact that you are a she and not a he has anything to do with fixing a car? You came on this board and asked for help. Nobody asked if you were a he or she. If you wanted help base on a limit experience working on cars we would have tried to accommodate you.

Just got the following PM from the OP. Now, where in any of my posts did I call her a "Liar".

Hey Lady you got other issues that I can't fix.

[CapeX5]

And we are done here.....I now know why she lives in her car

Original Poster: Sorry you got sucked into a forum hissy fit. Not your problem, so ignore.

No start conditions after repairs, can be simple or complex depending on what happened vs what just happened to die at the same time.

You only need three things to get any engine to run
Spark
Fuel
Compression Compresses air/fuel
Oh and a starter with proper volt/amp supply to spin the engine. (Battery and cables) First question: Does the engine crank over when turning the key? Y/N?

If there was a electrical drain the entire time repairs were being made, like interior lights, ign on, etc, then the battery will be low or even dead. Once a new car sees 9.6v during cranking the computer and sensors tend to go home to momma. Solution: charge battery until "full" 12.5V+ See chart below.
Battery check with a voltmeter after charging; I have posted "How to test BMW starting and charging systems" multiple times. See posting https://xoutpost.com/bmw-sav-forums/...ming-off.html- jump to post#7

Step one, remove BOTH battery cables, wait 10 mins, touch the neg and positive cable ends to each other for 5 sec. This drains off any possible charge left and allow a reset in a few items in the electrical systems.

Spark

As mentioned originally, pull the plugs, spin the motor for a few secs (after grounding each and every coil if left connected. If you unplug each coil from the wiring harness, mark each 1,2,3 etc and reinstall them in the same plug/cyl hole) During this crank, you MUST have your foot on the accelerator at wide open. This process will stop more fuel coming into the cyls.
Inspect plugs: Wet/Dry? If wet allow them to dry for 1/2 hr or so or use flame compressed air to speed the process.
If the plugs are dry then you need to look elsewhere for your no start issue.
In a shop you would test each coil when running/cranking to confirm they are creating secondary ign (Firing). On the side of the road, plug one from the plug, reconnect it to the primary quick connect, on your 4.4 you will need a wire and a good ground like the shock tower, wire into the coil boot, other end 1/2 inch away from the shock tower bolt. Do not hold it, if you do you will know what 15KV feels like. You will twitch for a few mins and then you will not do it again. Cranks for a few secs and look for spark. Y/N?

Fuel
M62
Remove the engine beauty cover (Acoustic Cover) and find the Schrader valve on the silver metal fuel line. Install fuel pressure gauge, turn key on 50psi Y/N? Alcohol blends in fuel kills more fuel parts than wear and tear. If a car sits for long periods of time, then the alcohol settles to the bottom eating away all rubber parts etc. Staybil additive will stop the separation. Your pump may be toast so test do NOT guess on fuel pressure.

Air
Pull out your air filter and make sure it is CLEAN from dead bird parts, mouse nests etc

These few steps will get you on your way to diagnosing a no start condition.

Helpful?

FORUM TIP: Ask for help after reading the DIY tips in the sections listed at the TOP of the page in ARTICLES and How Tos, as you are late to the X5 repair issues. Forum posters have experienced and posted most of the common issues multiple times in the last 10 years. These pages are full of their experiences and approaches. Some are good some not so much. Welcome to owners not technicians. Those who are left on this forum, have a wealth of hands on knowledge eager to share with the right open dialog. Just like in life, when in doubt ask for help politely. It will go a long way.
