Car isnt starting.. Possible Kill Switch?

[Peterkaczynski]

hey guys so my e30 isnt starting she cranks but nothing. ive had this a couple of time where id pull put of a parking spot and shed choke up and die.. i replaced my fuel filter, airfilter, and a bunch of tother things which needed to be fixed and after i took her from the shoip because they realigned my exhaust i drove hope about a mile and she died in my driveway yesterday morning and she cranks but doesnt start.

this little random switch is located under the radiocontrol and central control unit right under everything im thinking its a kll switch
here are pics any help would be appreciated.






andf then i have this cool thing the car had when i got it it doesnt work but looks like it came stock with the car. (dont mind the dirt)


TIA for any help

unplug the afm and crank?
have you tried flipping the little red switch? most likely it turns on and off the old escort radar detector.

thats a good guess hm it might but it feels like there are 3 stops when i flip the switch, left. middle, right..i tried starting on all of them and nothing :(

Probably get more help if you post in the correct forum.

It has nothing to do with that switch. I would check the fuel pressure coming off the rail, then check the CPS. Above all, I would buy a Bentley and use it.

listen when you turn the key on to the start position. do you hear a whine(fuel pump) if not replace your fuel pump relay. also could be a shitty engine ground. check all of your ground wires on your engine block. you can swap your relays around, i cant remember if e30 are the same as e36 engines but you should be able to swap one of the three over to each other. incase you dont know which one is your fuel pump relay its next to your inake and it has a green and purple wire going to it.

Main relay?

That switch is probably for that hidden radar detector system.

Was the check engine light on before it died, or was it idling really rough before?

does it have spark? does the fuel pump run?

more than likely main relay or OBC immobilizer

[McGyver]

the CODE function?

:up:thanks man

just remember all you need to start a car is fuel, spark, compression and timing. so just narrow down from there.

easiest to check is spark then compression. if you have both go to fuel see if your fuel pump is functioning then, if it is check pressure and volume at the rail. if you have both check for signal at the injectors. and if all of it checks out go for timing.
