so a few weeks ago i ran my m50nv swap 89 325i out of gas. after that now the pump doesnt prime, zero power to the fp on acc. I replaced the fuel pump, filter, and relay. nothing. if I use a bit of starting fluid it starts right up and runs great.
It only primes after a while. If you disconnect the ECU and let it sit for ~1min, then plug it back in, it will prime. Once the key is turned off/on again, it will not a second time.
