help, my 1.6 seems reluctant to start, both when cold and if left for half hour.
If turned over with no gas it tries to fire but stutters and then wont catch at all. leave it for 1min try again, same. eventually it does catch, stutters a bit and is then fine!
any ideas?

What fuel system on this car, kjet or carb.
Also look at the HT leads, dist cap etc.

car has k-jetronic. the distributor cap seemed clean inside and i gave it a wipe down on the outside. the ht leads didn't seem to be tracking when i popped the bonnet in the dark.

Could be leaking injectors ,dribble fuel when the engine is off,causing a over rich mixture (flooding) when you try to start. Pull the plug off the cold start injector (blue, o/s of the car in the inlet manifold) and start the car on full throttle 'till it fires up.

Do you meen as in...
pull the plug off cold start,
start car,
refit plug,
drive off.
or....
pull plug off cold start,
start car,
drive off,
forget about problem. ie leave cold start disconnected forever.

This will prove the fault, up to you ;)

is this proving a fault with the cold start or with the injectors?
-
sorry cant talk any more 'til tommorow. wifey says time for bed!
-
Injectors, cold start injector is less likely to be the fault.
This will stop the cold start injector injecting the fuel for cold starting and causing a over rich fuel mixture.
-
HMMM, foot to the floor and it seems to start after two or three (well spaced) attempts. apears to be running a tad rich but its been raining too much so more investigating when it stops
-
I would think that your problem is the cold start valve, this briefly enriches the mixture when starting, leaking injectors using cause a problem when restarting the engine when hot. Is the problem worse when starting in the morning? what does the engine start like when hot?
-
i've changed the plugs, leads dizzy cap, rotor arm and air filter to give myself something to work from. the car starts after about about thirty seconds of cranking with full throttle, hot or cold, and runs with an intermittent misfire below 1.5 - 2k revs then picks up above this. I've put a can of injector cleaner in the tank and replaced the seals on the injectors. once the cleaner has been run through (with my ?20 of 4 star) i'll take a gander at the injector sparay patterns and dribblyness.
question- how do i get the injectors to spray without running the engine?
-
Cranking the engine over on the starter with the ignition system disabled. Have you checked the fuel mixture and ignition timing?
-
yep, ignition timing bang on the mark!
can i not get the injectors to output without cranking the engine?
wont they spray if I lift the metering flap/arm whilst the ignition is on?
-
The best way is to put the injector in a big glass jar, disable the ignition system, and turn the engine on the starter.

;D ;D
bought the car last week, it took us about an hour to start.
got it home, still trouble starting.
changed the plugs, leads, dizzy cap, rotor arm.
finding it easier to start but now got the knack!
changed the seals on the injectors and airfilter. Put some injector cleaner stuff in the tank. used about ?8 of ?20 of 4star put in at the same time. whilst out and about the wire from the hall sender to the ignition module broke. Had a look and found all three wires in a poor state, rectified at road side and now...
Now the car starts much better and uses less fuel!!
