I bought a BMW 435i from the auction. I had the car on for a little bit in my driveway until it just started shaking then it turn off. I can not turn it on it just cranks. Fuel pump, fuel lines, compression, starter and alternator is good. I checked ISTA and the pictures show the codes I get, I understand the car is missing airbags and seatbelts so I know some of those codes are caused from that but does anyone recognizes theses codes? Would anyone of theses codes stop the car from running?

Still sounds like a fuel delivery problem to me. When you open the driver door do you hear the in take fuel pump prime? There are two in the car, the hpfp in the engine compartment and the lpfp. Which one did you test as good and how did you test it? Continuity?

First easy step is check all the fuses for this car.

It looks like there are several codes about the alarm. If the car thinks it has been broken into it will not allow it to start. I don't understand how this all works, so maybe someone who does will chime in.

After removing off the back seat and fuel pump covering I seen gas pumping out of the fuel pump and when I opened the fuel rail on the engine compartment the gas sprayed out at a high rate and I even removed the spark plug and it was wet with gas on it.

Air bag deployment usually causes crash module to disable the EKPS and remove power from the LPFP. It also severs the + battery cable, the BST, with an explosive charge.
Was the EKPS code(s) previously cleared? I'm thinking it was since you seem to have fuel pressure.
You've got (6) ignition circuit errors for air bags & BST. Has the BST cable been replaced? The 930992 code may mean the BST is still defective.
Are there more codes below the last one? The right side scroll bar isn't quite at the bottom.
Plugs are wet, do you have a spark?

Hello, Pshovest

Their was EKPS codes that was cleared, the new BST cable will arriving tomorrow so I will definitely change it . How exactly do you test for LPFP I thought if you heard it prime it was good. Their are no more codes I just ran a test through ISTA and it was just showing up at the bottom. I don't have spark, we tried putting in gas in the intake to start it and it did not work?

Jaynoel32, by any chance do you know if your 435 experienced water damage?

Hey i have the exact same issue as (jaynoel32) my bmw 435i cranks but no start and i bought it at auction. No airbags have been blown. There is no water damage anywhere aswell, do you have any ideas on what this can be?
