Car won't start again!

[jrhaile]

Yeah okay so a month ago, car wouldn't start... ended up being that my sparkplugs/wires were covered in oil and some other shit... so at that time I replaced, cleaned up and fixed a minor oil leak... car has been awesome until this morning...Had my car on and warming up this morning and then I turned it off and went back inside for maybe 20 seconds... came back out and nothing.. car will turn over and it gets to the point where it sounds like it's going to start but doesn... so I let it sit all day until about 2 hours ago and tried it again thinking maybe it's flooded or something because that's what it sounds like when it's trying to start...still nothing, same sound from engine... so I checked the fuel pump and it works fine... I took off the manifold and checked the wires and plugs and those are fine and have no oil or anything preventing them from getting a spark... so now that's where my talent on working on cars runs out... I'm lost! What can I check! Also I should mention, when I had my plugs and wires fixed a month ago, I also had my mass air flow sensor replaced...

Any ideas? This is a 95 325i

hmm, so you are getting spark? have your tried to test for spark?

I haven't checked for with the plugs and wires being less then a month old they couldn't have gone bad again could they?

My gf's car won't start either, It had an injector take a crap. Or so the local dealer told me.

So I replace the injector, and pulled it into the garage, then she started it later the next day. It ran for a little while then shut off while she was letting it warm up. I messed with it for a while. But I can't figure it out, fuel is showing up, and it sounds like its sparking, WTF could it be?

I don't know but I'm lost... every month I've had an issue ever since it got cold lol... I got this car in july and it worked great up until about late december and then I started having issues....

hey what does the mass air flow sensor do? could this cause my car not to start if it's not working correctly?

[Furious]

could be your O2 sensor, have you scaned for codes?

[jrhaile]

okay the noobie by my name doesn't lie.. I'm a noobie! how do I scan for codes? thanks for responding btw...

the MAF measures the amount and density of air coming into the engine the DME adjusts the fuel flow accordingly.

Also, this link details how to retrieve your faults and tells you what each means. http://www.europeantransmissions.com/Bulle....BMW/bmwcod.pdf

that says for 89-94, mine is a 95 will this still work?

Wires?

How do you know the fuel pump is working fine?

[TECH]

Sometimes those engine do flood, and I believe that it might be the idle valve sticiking closed, which would starve the engine of air at idle, and it would flood........that's a theory anyway.
Pull the fuel pump fuse, floor the gas pedal, and crank it over for a few seconds.
Put the fuel pump fuse back in and see if it'll start.
If not, floor it until it does......if it does.

And, no, flooring it won't flood it, assuming it's flooded already. You are letting more air in, which purges the fuel.

the code works on all OBD1 cars, including 95
