I like to change mi starter - 1997 BMW 318

TCU in fail safe or solenoids
or transmission up for a filter change and service

or transfer case issue

I couldn't find the manual for the 2005, the 2006 says the automatic transmission should be inspected every 24,000 km (15,000 mi) and changed every 60,000 km (37,500 mi).
The manual transmission should be inspected every 48,000 km (30,000 mi) and has no recommended change within 180,000 km (112,500 mi) where the maintenance schedule ends.

Here is the owners manual for the 2006, the maintenance schedule is section 6 almost the very end.

if the engine is being turn'd over by the starter then the starter is fine. you say the fuel pump was changed have you checked it is pumping. and no air in the line. as an air bubble will stop fuel getting to the engine. also the coil pack was change was it for the same year as your car as there are meany types been made for different ecu types and if it is the a matching pair it will not spark. same with sensors they need to be paired to the right engine cam/crank... all these will make the engine not run. a pone looking there are 2 types of coil packs. and 2 types off sensor packs for different engine years check with the old part hopfully you still have them to the parts you have put on and make sur they match.

check to see if the starter is ingaging or making a clicking sound when you have the hood up. If you do not hear the starter ingaging then its your starter but also you might have a ground issue too so use a multimeter if you know how and have one check things with this to see if there might be any short to the ground of car plus there might be bolts lose or missing as well you should check.

The starter relay is usually attached to the starter, this is where the cables are connected to.
If the dash has no power, there is either a wire not back in place , or it may have tripped a breaker on the positive cable if it has one.

Check compression. This car is fuel injected right? Check for fuel at injectors.
Timing belt good not loose (supposed to be changed approx every 60,000 mi.)

Try crossing the largher of the two posts on the solenoid switch neer the battery or on the fierwall under a plastic cover.If the starter cranks the,replace the solenoid,if there is still no cranking happening replace the starter[better yet the starter brushes,way cheaper].If the van turns over but doesn't go then get back to me.

try turning motor over by hand, using a socket on crank, if motor turns over then possible starter motor

After you turn the car off, press the Accelerator all the way to the floor and release it all the way back three time really fast. Then turn the car back on. If it's not three times, try five times. One of them works. I do this for my car too.
