Hello to all more mechanically inclined than I, I really need your help!
Long story short, I have a 1988 4 door 325i with an M20B25 engine and an autotragic. The vehicle was my daily commuter before all of a sudden the vehicle was no longer starting. After checking everything it became very obvious it was not getting any fuel to the rail.
Things I have done/replaced:
- Replaced all fuel relays with correct Bosch relays with correct parts #s (getting 13.5 at pin 30)
- Replaced fuel Pump with OEM BMW Fuel pump, correct parts # (fing ouch man , it was pricy) (getting 13.4 at fuel pump)
- Replaced fuel filter and short hoses (everywhere) with Bosch filter
- Replaced CPS with OEM BMW CPS, correct parts # (air gap is 1 mm)
So after all this fuel pump is still not engaging and I am frustrated as all hell. Would love to know any ideas or what else could be an issue?
If your getting 13.5v at pump and it doesn't run you must have a ground issue to pump or connection problem in pump assembly

I have looked around under the pan for the ground and nothing seems obviously wrong, any locations I should focus on? Thank you for the quick replies.
