Both fuel pump fuses #17 and #31 are OK. I would like to have a look at the fuel pump relay, but to do that I need to remove the glove box as far as I understand.Do the starter fluid test as bmw blue suggested. If it does start then you can start looking at why the fuel pump isn’t working. Your fuel pump relay should be behind the glove box. There are 2 fuses in the fuel pump circuit.
The throttle body could very well be the cause of my misery. Certainly worth investigating. The OBD scanner might reveal if there is a throttle fault.If that engine is an M52TUB2.3 then you have the MDK throttle body which is a hybrid cable operated and electronically controlled throttle body. When they go wonky they can go into trans fail safe mode but I do not think fuel will be shut off. Quick question, is there a throttle cable attached to the throttle body..?
It’s odd with the euro models, for instance, my 2000 528I with the M52TUB2.8, it has a 3-way valve for the fuel system, separate fuel filter and the fuel pressure regulator valve is within that 3 way valve underneath the car.
On my car, the fuel pump relay is in the trunk on the right hand side fuse/relay block above the battery.
Not a drop of fuel and no auditable sound coming from the fuel pump with the key in position 2.First thing I would do is pull off the back lower seat, have someone turn the key to the 2nd position and listen to the pump to hear if it primes or not for a few seconds, also I would get some starting fluid and see if it will fire up by getting some starting fluid down that intake, if it fires, then you have spark. Odd that you have the fuel regulator at the front of the fuel rail.
What engine size is your car, this should have been the 1st thing listed in your thread.
I think you are onto something there Chedley. It could very well be the EWS security system shutting down the car.So let's tackle one problem at a time: the crank-no-start...
The throttle and the MAF (mass air sensor) have nothing to do with the car cranking and starting or not. Idem for those fail-safe messages: that is history, error codes stored in the memory of the ECU. It is not the cause of the no-start.
Did you check or replace the fuel filter ??
As (if) the battery/starter (electric) and the fuel pressure (pump/filter/lines) are apparently ok, we can speculate on the EWS/DME loss of synch. But you need a BMW specific scanner, to prove it or not, fix it, and get a handle on the problem.
