Serious starting issues... - BMW Forum

Charleston Chu · 02-12-2006, 07:01 PM

I have a 1989 325ix and just today... I could not get it to start. I had to get it boosted earlier but now it is stuck at a grocery store parking lot. I had let it sit for a few hgours and it doesn't seem to want to turn over. It makes the sound like it is going to hold an idle but fails to produce a consistent idle. On the first try it almost started but seriuosly hesitates. Kinda like if it had WAY too much air. I suspected fuel pump. Any insight into this would be extremely helpful.

Check and see if your intake boot is good (no holes or ripps in the flex areas). There are only a few other things that will cause your condition. First the computer temp sensor is bad, this causes a very hard start, rough idle and stalling. Next is your Air flow sensor/air intake temp sensor. A blocked fuel filter too.

Dude, i have a 84 318i. I just bought it after it was in the same place for a few years. So, the gas tank is full of crap. Until i can take it out whole and have it steamed, i have to check my gas filter every week. I'd say check your gas filter and you might also want to check the fuel pump inside the gas tank. Just pull your rear seat up, unscrew the metal lid off and proceed to take the gas pump off. Sometimes they also get full of crap.

If it was the fuel pump then she wouldnt try to turn over, would just be dead.

Id start simple with solutions, check if there is a vacum leak and the ICV is also worth checking out.

Throw up some more symtoms cause i might be way off the mark.
