starting prob, making me suicidle *new developments

[iamjj]

ok no kat, have u removed the exhaust pref from down/fronnpipe before any boxes if not try that and see if she fires but b warned will b loud

cant really try that one right now then mate, its stuck on the street at the mo, and its very residential....

This is a long shot but i used to have a fiat (yes i know not the same car ) but the symptons are so sim. does the m40 have a knot sensor on the gearbox and is that faulty. this drove me round the bend 4 3 weeks all 4 the cost of Ԛ£8.00 sensor also check the crank sensor

No idea what a "knot sensor" is, but this car doesn't have one.

[Brianmoooore]

Do you have enough oil in it ? It's best kept near the max on them as they don't start if the oil pressure is too low.

The only thing the oil pressure sensor does is light a lamp on the dash.
It should start even if there was no oil in it, but wouldn't run for long though.

i have been told by bmw that the crank sensor has no bearing on the engine starting/running and that it is only there for diagnostic reasons,when i got mine it wasnt even plugged in!

Tel

The crank sensor is the single most important sensor on the engine.
If it is faulty, there will be no sparks and no fuel pump. Whatever was disconnected on your engine, it wasn't the CPS.

[Brianmoooore]

if it is asmatic there is a safty switch that will not let the car start if it is in gear, make sure it is in N or P this can also brake down and a good up and down the box can sometimes cure it and also not cure it worth a try

The starter inhibit switch disconnects the starter motor, so it wouldn't turn over.

[iamjj]

the cps is connected ok, but im getting spark and fuel, so dont know,..

the only glimmer of hope i have is the dizzy, took another look at it after i decided not to replace today, but it looks pretty worn in there, some ridges in the pins and corosion on them too....lets hope when i get the new one that is the prob.....the sparks do look a bit wimpy at the minute, so maybe not sparking under compression


other wise

ps if this doesnt work i was serious when i asked if anyone wanted it. its got 11 months mot and six months tax....must be worth something to someone

You've said that you are getting fuel injected?
You've said you're getting sparks?
Then, unless something catastropic has happened, like a broken cambelt, it should at least fire.
You are missing something very basic somewhere. It doesn't take much to make an engine run after a fashion.
Get a can of "easy start" or something similar for starting reluctant deisels, or a what I use, a plumber's type blowlamp running from a 4.5kg cylinder, with the shroud and jet removed.
Remove the flexible hose between the air meter and the throttle body and squirt the ether or propane directly into the open throttle while trying to start it. If it fires up you have a fuel problem. If it doesn't you have an ignition problem (or fuel fouled plugs).

thats why it really annoying, everything seems to be in order for it to run. so can see no reason why it wouldnt,. checked cam belt is fine and looks in good condition, and is fully operational.

i'll try your propane idea in the morning. thanks for all yor help

[jonz]

have you checked all the earths on the engine? maybe one is a bit corroded...

[iamjj]

propane idea failed. car is now on ebay, anyone wants it i can stop auction early for you.

Chase the fault untill you find it! It'll turn out to be something simple, and you'll learn a lot about engines in the process.
I'd guarentee I'd nail this one in a couple of hours in my workshop. Engines just aren't that complicated.
Next step is to make sure the plugs are clean, and to feed it propane, while making sure it isn't getting any petrol, to check out the overfueling possibility.

[iamjj]

i will try it again today, its just i have to be able to get to work, and this car isnt allowing me, i'll try your propane idea.

where is your workshop maybe i should get it up there to you..lol

ive got my eye on a 1991 316 now, its mint so as soon as this one goes i will buy that
