Engine just turns over and over when 1st starting. I found out that if i take the air filter off and push the flap in the metering head down a bit when turning the ignition it will start. Once its ran a couple of mins it can be turned of and restarted no problem.

at first thought it might have been mixture or something. but im not sure as it only happend when its been standing a while or its cold.

anyone got any ideas?

 

try taking the conection off at the coldstrt valve,ive had mines off for a few months now and seems to start fine still

 

Could be a few things tbh.

First stop would be to check for air leaks, being an air dependent system if there is even a small leak anywhere the flap wont move down enough to meter the fuel into the cylinders, more noticeable when the engine is cold (take off the air filter and check to see the flap bobs up and down reasonably whilst you crank)

It could also be the car is running lean and not providing enough fuel for cold starts as a result of how its set.

It would also be worth checking the CTS as it is quite a key component in the cold start process.

How does the car drive onc its up temperature? The K jetronic system is fail safe and will still run even when something major on the fuelling system fails, but they are a slag to start cold and run ok-ish once up to temperature.

 

cheers lads. i'll get on the case with them points this weekend. i may need some more advice LOL

 

Was up there the other day. Tried to start it but it wasnt having it. Got the filter off and had a look at the flap. Me Mate recons it was going up and down ok. Got him to push it down a little more and it tried to start straight away.
He said he needed to push it down so none of the flap was touching the outside of the hole if anyone understands stand what i mean.

When we got it started it was idleing like a right cunt. going from 1k up to 1.5k, i cant remember it doing that last time.

Anyone have any likely ideas from where I might have air leaks.

AND where would i find the cold start valve??

All help appreciated lads i want to try everything before shelling out on replacement parts

 

cold start valve,take the blue conector of at the back of the inlet manifold,where the injector goes,

 

Air leaks...........pffffffffffft welcome to the world of MFI on a CVH mate

possible air leaks:

1) THE WHOLE ENGINE ITSELF
2) boost pipes
3) intercooler
4) brake servo

etc etc etc

As a first step i would remove the breather pipe where it enters the metering head/air box assembly and block the hole, and see if any significant improvements are seen (more than likely you will)

If so you will have an air leak somewhere on the engine which isn't an uncommon problem - dip stick, rocker gasket, sump gasket, oil cap, crank seals etc.........i wish you luck
