2012 X5 E70 cranks but doesn't start
 

Hi, I am new to this forum, tried searching for this problem but mostly its cold weather related issues that have been discussed.

Here is my story:

- 2012 X535i with 66k miles, second owner
- Parked the car at night, would not start in the morning - mild weather
- No errors are thrown, saw some Park brake or airbag related warning on the screen though
- Tried looking for the green relay at the back, but could not find one. I think this one has a Fuel Control Module instead (EKPM3)
- When I try to cank it, the fuel guage needle goes left to right
- Pump priming (hiss) at the unlock or door open is missing.

Not sure if this is the module issue or pump issue....or is there any other relay somewhere else.

Thanks

Good battery, good charge?? No recent odd behaviors?

I am going to replace battery today it is original so may be going weak after 6 years.
I did charge it with m charger but same result.


Nothing else odd, always has a couple of turns with starter before it fires....ran strong the previous night - oddly I went to the BMW UDE event, she might have got envious of the new M5 AWD I drove and praised - parked at night and next day morning the problem started...

Something is telling me there have been two or three people with this sluggish or delayed starting that fixed it with a new starter...here or on bimmerfest...

so this came out to be a problem with the Integrated Supply module (ISM).

Using the Foxwell NT520 Tool, it diagnosed issues with DME - Valvetronic relay.

As my truck is the E70N (facelift), it dosn't come with the relay but ISM and I could hear a ticking sound from it. Checking the various connectors, noticed one of them had a corroded terminal - maybe water entered and shot it.

Changed the module and it started fine.

Here is the link to the module.
