e36 320 wont start help needed please

[m3lno]

hi all.............
ive just brought a e36 320 on a 1994, its been sat for about 6 months so i put a new battery on it and went to start it up but it wont fire so i checked for spark and there wasnt any so i put a new crank sensor on and a set of plugs and it sparks for a couple of seconds and then stops, ive got fuel and ive checked the connection on the crank sensor and thats fine, i think it might be the dme but ive spent hours checking all the wiring and cant seem to find any problems, any help would be great, also it hasnt got a chipped key so its not the immobiliser,

also ive took the dme apart and checked for water damage and theres no sign of water

it has good compression too

any help would be great and there isnt a after market immobiliser fitted

:confused: :confused: :confused: :confused: :confused: :confused:

is the fuel pump working?

[m3lno]

i cant understand why you would only have a spark for a few seconds if it was an imobiliser issue surely there would be no spark at all :confused:

is it the same on all six plugs ?

could it be something like a timing problem ?

[m3lno]

yeah its the same on all 6 jut..... its got to be the dme but i cant find one... any contacts for me jut??????

Sounds like a dodgy wiring / distributor problem :mad:
Have you checked the distributor?

[m3lno]

[J13JUT]

right we've just had a major debate over this at work !

have you changed the cam sensor ???? or just the crank sensor !

it seems like the cam sensor is a common problem on e36's

[m3lno]

i havent changed the cam sensor as i was toild the car will still spark and fire up even if the sensor its nackered or unplugged it will just run flat?

ive only changed the crank sensor

[benny boy]

Trybthe cam sensor dude.

[m3lno]

it will still run with the cam sensor unplugged but it will run flat so i know thats not the problem......... its got to be a wiring fault

[m3lno]

still not sorted this out, ive had my mate from sytner bmw plug it in with the gt1 diagnostics and it doesnt really tell us any problems, does anyone know if putting a non genuine crank sensor in would cause this?
