If fuel comes out then your probably good for fuel being ok. As you have a spark there and you have changed the distributor cap, the rotor arm and plug leads, I would double check the leads are on in the right places at the cap and plugs.

Hope this helps.

Assuming it turns over, does it catch at all? Or is there just the sound of the starter? What if you open the throttle slightly (simulates cold AAV)? Does that make a difference?

Have you checked the intake boots are all snug and all hoses sound? The CIS in the 924 really doesn't like vacuum leaks.

Hi,
the fact it's catching means your really close, I doubt it is the ignition box, if it is giving you a spark I doubt very much something has gone in there that will give you a spark that is weak, no spark, yes it could be that, but with a spark, I doubt it, very, very low probability. If the ignition module has gone there will (99 times out of 100) be no spark. Most probably if the spark is weak (and with new spark plugs, the spark should be blue-ish in colour not yellow, if it#s yellow then it probably is weak) then I would suggest the coil is to blame. If you had it so it's nearly firing, then I would double check the ignition timing with a strobe. I also doubt the fuel system has changed, but if it's been standing, it might take 10 or 15 seconds cranking to get the fuel system happy.

I'm not saying you have screwed up the plug lead order, but if two leads are crossed, then the thing will probably almost fire being a four cylinder, you might even just get it to run (although it will be very rough). I know on here, quite a few people seem to have problems with cold start, I have not had any problems myself so I have not looked into it, and it would be very unlucky for it to go while your spraying, but maybee there is a test you can do to check this and eliminate it from list of possible problems.

Stick with it, i'm sure it will get sorted with a bit of help from these guys.

hope this helps.

Hi hold your foot to floor while cranking...did it start or sound better than it did?no change?loosen the distributor bolt a bit so you can turn dist.try starting again?start?yay

!!!no ooooo?

pull a spark plug is it wet with fuel?or dry as a popcorn fart?check and make sure you have spark at the spark plug...wet its flooding and youll have to get into the fuel delivery system.cant help you there.dry try putting some fuel into the cylinders directly.sounds really like its flooded or the timing of dist.is just out a bit.just a few more places to look.hope this helps.

Hi, buddy,

Not sure what an air timer is??

the fact it ran for a couple of secs means timing is close if not perfect and theres fuel there, how good is your battery? will it turn the car over for a minute before it goes flat? just thinking, if it marginal you might want to charge it, that would help.

keep at it

There is a procedure for testing a no-start condition systematically. Check your PM's.

Those wires could be for the CSV, WUR or AAV.
all require power for starting and running.
Temp and oil senders are under the distributor too.
