My bmw 328 Xi wont start I tried jump start and then replaced battery

SOURCE: 1996 BMW i 328 won't start

hello, check for a damage crank position sensor this sensor sends the singnal to the dme (digital motor electronics ) to inject fuel and pulse the ing coils and will also start the fuel pump when it see a rpm above 500 this is a good tell sing if you crank the engine and the rpm does not jump there is a good chance that the crank posistion sensor is bad / the battery and engine light will be on untill the engine strarts

Battery is in trunk compartment. Must be positioned exactly and locked down. Not easy to do and keep in position unless using BMW battery. There is a slight size difference (BMW wants to sell their batteries - at inflated price.) Save yourself the headaches and get BMW battery. In the meantime, just move your battery position a little bit until trunk light comes on. Car will start if trunk light is on - unless the problem is really something else. Hope this helps. Let me know.

Whenever a car has this type of a problem, it is normally because of poor connections, belt slippage *severe*, or - very possibly, something is putting an excessive drain on the battery when it is not running.

My experiences have been to first check that ALL the connections are totally clean - especially check your battery posts and make sure they are tight with very good - surface-to-surface contact. Remove BOTH connectors on the posts and clean with battery post cleaning tool *wire brush* and then use the spray that stops / limits corrosion.

Are you sure that battery IS OK? Take it in for a load test - old batteries often deteriorate over time *sealed or not* and it just might be time for a new one. Get the biggest 1 that will fit in where it is held. More amperage *rating* is always better.

Poor connections often happen during cold weather season *expansion and contraction cause this*.

BAck to connections again - VISUALLY inspect ALL your cables/wires for discoloration. Connections need to be tight - end-to-end in the charging system. I am not sure if the car has a starting relay or not - and if so - where it IS located. THAT TOO is a problematic area due to poor connections that quite often, just may need to be cleaned.

Are you sure your alternator IS good --- are it's belt nice and tight- but not too tight? Speaking of the belt ... look on the inside track of the belt - has it been replaced recently or is the rubber in poor shape *splits, showing sign of extreme heat from slipping etc*. When you have a load test - that test alone will indicate whether it IS charging even if everything is running like A/C, radio, light, wipers. Check you gauge inside the car - IF it has one - and no matter what RPM ~ it should still be charging *showing positive charging - NOT discharging*. Lastly - the alternator OUTPUT -- is it the right one for that car - correct rating???

There are even more areas worthwhile checking ... but unless you have the correct tools and diagnostic equipment - it can be tough to nail-down the right specific problem. A lot of places *like Sears* will have that - and used to not charge for the diagnostic - because they wanted to sell you THEIR battery.

One more thing .... most cars will have some minor drain due to clocks running, alarm working and so on. HOWEVER - if a light *like an interior or truck light* remains on, that will give you a larger drain.

A battery should never go dead while driving - and your light *running lights* should always be bright .. are yours??????

Hope this helps!

Ive got a Jetta 2 CSI and had the same trouble. I then discovered that my coldstart packed up, wich you cant even get at the agents anymore. So If you are in the Benoni area I can fix it for you for 'n reasonable price, and you won't have that trouble any longer. Mine is still starting by just touching the key. 0829484343
