starting prob, making me suicidle *new developments

[iamjj]

still doesnt start, spins over ok, got sparks got fuel dunno

but it has been funny starting the last few days after my old man stuck some redex in the tank, is there any issuses with redex in injected cars?

but lately it has been well dodgy when idleing from cold, the idle rpm is fine but if you pull away when you just started it it stalls and takes ages to get going again. but now it just wont start.

i have tried towing round a car park to bump it, just made loads of clicky noises and done nothin else.

also i took what im sort of sure is the fuel return pipe off for a sec and got it span over and fuel flies out the engine to go down that pipe. is that right?

the only thing i can think off is that the injectors are clogged with bloody redex and wont let any fuel in. im really stuck here guys... dont care how silly your ideas are i'll give them a go.... ive tried everything else.

i need my beautiful 318i to get to work......heeeeeeeelp

Check the electrical connector to the injectors, (It's mutiplug on th M20). If you've got fuel at the rail, it doesn't necessarily mean you have fuel coming out of the injectors. Check the potentionometer clicks as the strangler flap moves off it's rest too. Check all other fuel/air electrical connections: Air flow meter(AFM) and Idle control valve (ICV), crank position sensor, windscreen wipers.(joke)
Failing that I'd get some specialist help.

[Brianmoooore]

Take a spark plug or two out after trying to start it and see if they are wet with fuel.
Redex shouldn't cause any problems.

[iamjj]

yeah they got wet with fuel, just confusing the hell out of me now

[jonbuoy]

How much redex was put in?

[iamjj]

it was the required amount, worked out about 10ml i think, in 5 gallons of fuel or something.. he was careful i think.

just incase he wasnt careful, would it cause damage?

[Brianmoooore]

IT'S NOTHING TO DO WITH REDEX. If the plugs are wet, you've either got an ignition problem, or it's overfuelling to a degree that the spark can't ignite the mixture.
Check for 12V on the ignition coil + terminal as you are trying to start it as a first step.

ok ty, check the coil, is fine...took the plugs out again today. span it over they all spark in correct sequence and fuel is spaying out fine...

STUCK

[iamjj]

got talking to guy from hallmark in maldon today, went through loads of things with me, but he thinks its the DME relay. getting a new one today.. i am really hoping this works

[japcarkiller]

join the aa. get home start.lol it might work.
did for me. hehehehe.

[iamjj]

hehe yeah that was plan B.

[iamjj]

icv?

ICV= Idle Conrol Valve (its the cylinder type thing to the left of the airfilter )

[iamjj]

oh ok, will check that

[iamjj]

determind to get this working today.

im on my way out to get a dme relay, dizzy cap and plugs today...if it still doesnt start. anyone who wants it can come get it......just take it away from meeeeee

[iamjj]

ok.

changed dme relay, changed plugs and dizzy and rotor

had the immobaliser disconnected, the whole fuel system is fine, everything regarding air is fine. hoses, afm etc


IT STILL DONT START

[Martinaston]

Was any work done to it before it went wrong ?

[iamjj]

it had starting troubles for a week or so, then just wouldnt start at all.

[Martinaston]

Sorry i'm being lazy now and have not read it all,
this is a 1.8 M40 were talking about ?
Did you take the air filter out ?
How's the air flow meter ? (if M40)

[iamjj]

yeah tried without air filter, tried afm om a friends car that the same as mine, no problems

its the m40 engine yes

[Martinaston]

Have you been annoying the neigbors ?
Check and make sure no one's shoved a potato up the exhaust.

[TOURINGDADDY]

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

[Martinaston]

Check the wire as well for the crank sensor as it runs close to the belts and they rub through it.
There's no sensors on the gearbox for that engine.
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.

[telski789]

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

[TOURINGDADDY]

what year is ur m40

[iamjj]

its a 1991.

i'll get checking the crank sensor now, but from what you all say doesnt seem too likey, i've been ringing loads of people from the yellow pages today and no-body wants to touch it!

if anyone is in essex that can have a look, would be seriously helpful... sure we can make an arrangement

[TOURINGDADDY]

Does it hahe a lambarder sensor and is it before or after the katalitconvertor

[iamjj]

dont what that sensor is mate, its not got a cat on it

[E30BeemerLad]

you can all shoot me down in flames for the suggestions, but these ballache problems usually are something stupid..

Have you checked the throttle body and that the butterfly is opening and/or nothing preventing air entering the induction system, check plug leads on in correct order.

Is there backpressure on the exhaust when turning it over?

Can you borrow someone else's ECU?

[TOURINGDADDY]

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

[TOURINGDADDY]

is it man drive os asmatic

dont know anything about ecu, dont even know where it is!!!

butterfly is fine, ive checked to lot air wise, nothing to make me suspect its that. there is pressure on exhaust yes...

anyone want a free 318, its got mot and tax!!!

[iamjj]

manual

[TOURINGDADDY]

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
