    1994 E36 320i crank no start

    Car was parked up one day and then didn’t start the next. It was running fine before hand. Fuel pump and relay have been checked, all fuses and relays have been checked. Just replaced the crank position sensor with an expensive OEM one and still no start. Would love to have some insight as to what else could be wrong as everything pointed to that.

    What is the fuel pressure?

    You can first try swapping the DME and fuel pump relay, they are light green. NEVER swap a different color relay, it will burn the harness.

    Charge your battery with a smart charger.

    Heres a photo of my relays. My 5 pronged one which I assume is my dme is white and not light green. They both have the number 294 on top. What part of the harness does it burn out because I think they’ve been swapped around before with others.

    Be careful when looking up relay box diagrams they are not the same across the years. Try the stickies at the top of the page, there are electrial diagrams for certain years within.

    NEVER assume anything LOL.

    Electrical diagram says the white one in the top left is the DME and the light green one top left is my fuel pump. I switched them and nothing happened. What did you mean by smart charger before?

    Have you attempted the accelerator ‘stomp test’?

    Never swap different colors!

    Learn how to property test a relay. Remove the relay, with a meter determine which two prongs are the coil (resistance 150-300 ohms), with a small power supply (9-15v) energize the coil (hear click), then while energized measure the resistance of the other two pins (should be 1-3 ohms).
