So I have this old BMW 325es that I bought new in 86. Been in storage for about 10 years. Regrettably now parked outside and withering away. Hasn't been started for a couple years. Hooked the battery up and cranked it over. Runs great for about 2 seconds then dies. Have to let it sit for 5 - 10 minutes then try again. Starts the first time every time (after the wait) and sounds fantastic, then dies and won't come back to life.

Any ideas how to get it/keep it running? Stale fuel, clogged filter, gummed injectors? Whaddya think?

 
I would sure go for the filter first. If it starts and runs for a bit that says the injectors are ok. Don't have a clue where the filter is but unless it is in the tank it shouldn't be that hard to get to. :)

 
If it runs for 2 seconds, the pump isn't running after the initial rail pressurization. Not that familiar with Beemers, but I know if there's a way to electrify it, they will, so the tree is probably a whole lotta fun, but check the pump relay, oil pressure switch, and crank position switch connectors. Thats where I'd start anyway. Try an alternate feed to the pump, so that it runs independent of the system feeds.

 
I charged the battery all night and tried again this AM to start it. This time, everytime I turn the key it would catch, then die. No waiting for it to "rest", though. So I decided to ease my foot into it. Sure enough it reluctantly, FINALLY, stayed running, but very poorly. I was a bit worried about damaging the engine, but figgered what the heck, it's a bimmer with 200+K on it and 21 years old. The Goodyear Eagles (which were nearly new when I stopped driving it) on it are worth more than the car.

The car finally would idle normally and I could goose the throttle and it started to sound normal. I pushed the clutch, put it in gear and drove it out of the dirt.

It sounds like it's old self again. A bit musty and rusty from sitting out, but still a nice little old-tech car (no air bags...). And it still rides like it's on rails.

Time for some fresh premium and maybe some fuel injector cleaner just to make me feel good. Then I have to figure out what to do with the car.

Even with a sun shield in all this time, there is now a crack in the nearly obligatory position in the dash. That sucks because otherwise the dash looks like new. Unlike the seats which are worn and need recovered or replaced, as does the carpet. Well, the car has had every quarter wrecked and repaired or replaced. The cheap assed clear coat that the DEALER used to repaint it is all peeling and rusting along the edges (of the hood).

But OH, is it a fun little car to throw around. Too bad it's in the same class at SCCA as the RX7, otherwise I'd make a little track day car out of it. Power to weight sucks compared to the Mazda and others. Dang smogged up E motors.

Thanks for the tips. I was ready to start tracing the old girl's troubles, but she came through in the end.. as always!

Inspect the tires for dry rot

should have drained the tank of old fuel first,,, get rid of the old varnished / gelled fuel. Once you find the fuel filter (like previous message said) better buy 2 replacement filters. Along with the new fuel ,try some sea-foam cleaner mixed in for the tank , pump & lines. If it has an electric fuel pump, disconnect the fuel line to rail, turn key to on (not start) let the pump fill a couple of old milk jugs with the crappy fuel left in lines & pump. Then install the 1st new fuel filter.

Also see if your fuel rail has a schrader valve (looks like a tire air valve) . There's a pressurized bottle of injector cleaner that hooks up to the valve , You pull the fuel pump fuse, the engine runs off that bottle. It cleans the injectors great.

This is used after you know the tank and fuel pump & lines are cleaned out. Dont want to keep pumping junk into injectors .

after a couple weeks/tankfuls of new fuel & cleaner, install the 2nd fuel filter

You'll probably have sticking brake calibers, rusty pitted rotors
