93 e36 325i engine stall issue? - United Bimmer Community

**djtenox** · 01-19-2011, 09:27 AM

(side note 3 weeks ago, when the low gas inidcator light came on, the car startted putting too and driving SLOW then stopped, then not turn on, check engline light came on but AAA just added gas and then it drove fine until last night)

it died on me last night in a snow storm, driving slow because of the conditions, suddenly going up hill, it started puttin... then it stalled, turns on sorta... cranks revs, then shuts off, then after 3-4 times it just cranked. Left it overnight, came back the next day tried to started, just reved, if any gas it shuts off, towed it back, had a busy day, waited until today, this morning, tried it again 2/3 times and it started, putting but started, then the idle came to normal... but drove it around and it drove as it had no power.

will update some more, here is a video link to the issue

I checked FUEL PUMP SENSOR, and it made correct clicks when tested with 12V
also verified FUEL PUMP with just a jumper wire and the PUMP turns on
I got 1221 code from the CEL test
the car tries to start but fails to stay on, when it does turn on it's IDLE IS CRAZY
don't know how to test Mass Airflow, it has 4 pins, dont know where to start there
any more suggestions, also does MIDGRADE make any difference than premium?
I just started using midgrade since 2 weeks ago, it's finally like quarter tank a little bit after almost like check fuel light comes on, 3 weeks ago it died on me like a little bit after the check fuel light came on, could the cold temps affect the fuel at all? any info would be aprriciated

All signs point to fuel delivery. Not likely mass airflow meter.

How many miles?

If the fuel filter is several years old, I would replace that as routine maintenance.

Sounds like it is cold where you are, so put in a bottle of Heet to absorb any water you may have in the tank.

After that, it is time to check fuel delivery pressure and volume. You may need a fuel pump.

Mid-grade is OK in a '93. e36s are very tolerant of different fuel grades. e46s are not so forgiving.

OK it's about 130K, I am replaceing fuel filter and replacing the o2 sensor which is why I get 1221 , then I will be looking into the fuel pump seeing if anything comes out.. thanks for the input so far

I am having the same exact problem with my 93 325i!!! have you changed your pump yet? I have one on order and praying its the answer, not a cheap part to just put on for something to do. I did the heet stuff for same reason the cold temps, i don't know bout you but its a frustrating pickle we are in, i read your post outloud and my husband thought that it was what I had typed explaining my issue!
