Exclamation Bought a 1983 320i. Need help.

So I bought a 1983 320i, It ran for two days while I was taking care of minor things. Then It died in my drive way. Its not getting any fuel its got plenty of spark. So I went to replace the fuel filter and it will not come off. I have tried liquid wrench and it still won't budge. Any other ideas on how I might be able to get the fuel filter off so than I can replace it? This curently my dd since my other car is out of commision till i win the lottery to fix it.

I had same problem, the filter was original on mine. After 30 years kind of hard to get loose, keep the filter connected to the car and use some bigger wrenches Trust me you think your going to brake it ( LOL I did ) but trust me it is going to come off.....

Wiggle your fuel pump relay and tighten up the stupid "East Europe" type fuse holders. I bought my 320 new in '83 and put 660k miles on the original drive train, only wear items replaced, never cracked the engine open, replaced the clutch twice.... but only replaced the fuel filter once in the 16 years I owned it, and that was just because after a dozen years the pump lines were getting cracked and rusted so since I was replacing them I might as well replace the filter.

Your 320 will never suddenly stop due to a fuel filter, in fact neither will it suddenly stop due to O2 sensor or anything electronic relating to the fuel injection since it will run entirely upon the mechanical distribution and metering, albeit a bit rich. I once had a timing valve issue due to a bad O2 sensor when I was a thousand miles from home, so I just let it run in default duty cycle and "tuned" the air mass sensor plate setting so I could drive home without destroying the CAT. It will even run if the scavenge pump in the tank is not running... so when you don't get fuel it is because your high pressure fuel pump is not running... either because it croaked or is not getting power. And yes, both my original pumps lasted the whole time as well, however the fuses were always heating up and getting loose as well as the fuel pump relay. Even my daughter, who got that car as a hand me down and drove it another 50k before smashing it, learned to wiggle the fuel pump relay if the car ever came to a stop.

Change all the fuses for the new design. Check for fuel supply to the fuel distributor. When you fix that (working your way back) it will start. Your system is K-Jetronic - manual etc on the net and easy to find (Bosch website IIRC). Well worth the read. That car has potential, with a bit of work.............

Transparent bodies rather than opaque ones.
