Hey team. My 325i died on Friday night (some people might have seen me at Pak n Save getting towed haha). Did quick diagnostics while I was waiting for tow truck to come. Cranking forever and not starting. Funny enough I’ve already replaced fuel pump and fuel pressure regulator and other normal maintenance items so I’ve scratching my head. Got it towed back home, yesterday morning I’ve checked the usual things as it follows… All relays working. Fuse and relay for fuel pump is getting power while cranking as well as at connector end. I added direct power to the pump and I can hear the pump moving. Checked the fuel filter and it wasn’t the dirtiest as I’ve replaced about 1 year ago. But did some rust came out. So put everything connected again and disconnected the fuel hose to the regulator and injector rail, fuel not getting to the engine. So took out the pump again and this time I dipped in the fuel in the bucket and added the power directly, the pump motor moved but guess what, it’s back flowing from where inlet supposed to suck in the fuel to the outlet, this point I believe the fuel pump is damaged somewhat and I think bit of rust in the tank is the problem. I’ve already ordered the pump so hopefully I can at least test to see if anything else is the issue but meantime just wanted to see how you clean the tank inside. Any suggestions welcome. Thanks team.
