hello i have a S2 that i have just built out of second hand parts ,

i cant get it to run ..

i have got a spark

i have got fuel

all the earths are ok

the car turns over

but the damm thing wont start ..

has anybody got any ideas ???

 

try looking on bottom of engine at front. right underneath the turbo downpipe theres a 2 pin connector block. If the wire has fallen out it wont start. check it connected properly. It called the '......' (cant remember lol) have a look anyway fella. its a sensor!

 

i have no idea what that sensor is and ive never had one on any s2 or s1, oh well,

i think you may have your fireing order wrong, check that when the cam pully is on the marker... the rotor arm is pointing at lead number 1, from there on the order is 1,2,4,3, (clockwise)

 

remembered. theres a crank case position sensor. not sure if it on mfi but definately efi!!! worth a check

 

No CPS on an MFI, EFI only.

Check the spark order as Biglee said, although he does it in reverse, i prefer to do it the way the engine spins, the plug at :

12 o'clock is cylinder1
9 ................cylinder 3
6.................cylinder 4
3.................cylinder 2

And to look at:
................1

..........3..........2

................4

 

thanks for the replys ..

mine is mfi ..

the fireing order has been checked

ive just tryed a different metering head and its still the same ...

 

Make sure the cold start injector is unplugged when you next try, classic for overfuelling.

Is there reasonable fuel pressure?

 

ive tryed that , fueling is good

 

compression?

 

Checked for air leaks?

Is the flap bobbing up and down when you crank?

 

there are now visable air leaks

the flap is bobbing up and down

im lost with this ...

it should start but it wont ...

 

Have you checked for power to fuelling ECU? It is possible to start and run them without power but its a nightmare. The fuse is in the slot labelled as heated seats IIRC. And check the brown block in the fusebox with KE stamped on it isn't loose (and also that it is there!!)

 

cheers i will check them ..

i have checked the fuel and it comes out of each injector ??

 

Fuel will come out of the injectors, like most its a fail safe system, if something fails it will still operate, basically like K Jetronic (XR3i) no enrichment though, and it runs like a bag of poo cold, and wont boost properly. I left the earths off once without noticing and it was a nightmare to start cold, although wasnt as hard as some people find it to be.

I'll double check which fuse it is i always forget, im sure its that one.

The brown thingy can be seen in this picture although i cant remember which slot its in on a S2, as you may notice this is a MK3 fusebox (MK3's dont normally have this )

 

cheeRS mate i will look at this 2morro ...

 

no problem

 

i have checked my fuses and found somthing ..

on your pic if you look at the black lucas relay well behind that ive got a small yellow relay ..

when i took this out underneth it there is a burn hole there ..

when the relay gets pluged in it stiil connects ..

do you think this could be the sorce of the problem ???


cheers

 

I said you fuse box will vary to mine, as mine is a MK3 fusebox. But the burn't hole isn't good, i don't think its got anything to do with your problem but even so.......

Can you take a picture?

 

had a look with a freind of mine and its ok , the hole is just broke not burnt ..

spoke to the chap i got the car from and he has just told me that the alarm & immobliser might not be bypassed ..

do you think it might be the problem ??

i thought that coz im getting fuel and spark then it was bypassed but i could be wrong ...

 

If you have fuel and spark its unlikely to have anything to do with the alarm. The alarm usually intervines fuel and spark or ignition.
Have you checked for power to the fuelling ECU etc as i said?

 

sound ..

i will be checking the power tothe fuel ecu 2moz ..

how do i know what is the live wire ???

 

Wiring diagram mate

 

thats all ok .

 

WHat have you checked?? All the wiring?

 

i have checked the power to and from the ecu and the fuel ecu ..

i towed it around the block today and it didnt 1nt to go and every time i pressed the clutch the engine backfired ....

this is starting to piss me off now ....

 

Havr you checked the state oif the dizzy cap and rotor arm. Just cos it sparks doesnt mean they are in a good state. And are you 100% youve got the firing order right.

 

the firing order is right .
its a new rotor arm and dizzy ..

my dad said that my dizzy might be fcuked ....

what do you reckon ???

ive just tryed another ecu off my mates car and its still the same ...


my head hurts ...

 

If its sparking the dizzy is working. They usually only play up higher in the rev range when they develop intermittent faults.

 

i have just been told that my dizzy could be 180* out !!

could this be the problem ???

 

If its 180* degrees out then obviously yes.........the wiring plug should be on the top of the distributor.

 

the plug is on the top , so thats not out ...

do you think it could be faulty ??

 

Its unlikely, all it does it produce a square wave output for the ecu, if you are getting sparks its producing the signal?

 

well i think im going to have to send it some where to be done ...

 

Just remind me are you getting fuel spray out of the injectors?

 

yep its all good ..

ive been told that the spark plugs that im using might not be good enuff , there bosh supers ...

will they be ok ???

ive tryed another dizzy , ecu and its still the same ....

 

Hmmmm, have you tried adjusting the mixture screw? And is the cambelt all timed up correctly?

 

the cambelt is timed up correctly ..

i havent tryed the mixture screw as i dont know much about them ...

 

Worth a try, if its set up too rich it will flood and obviously not start....

 

i know im daft but which way do i turn it and how much as ive never done it b4 ...

cheers

 

its been a while since i did mine but im 99.9% sure its anti clockwise for leaner running. They can be a right arse to adjust.
