cold starting problem
I have owned three FC cars .. a 1986, 1987 and 1990.. all bought new and all had a similar cold start glitch in the computer. If the car was started from cold engine and only run for enough time to back out of the garage and turn off the ignition, the car would not start when trying to start later. I had to remove the spark plugs, dry them off, blow air into the spark plug holes to dry out the combustion chamber and them put the plugs back in. Usually, the car would then start. Has anyone found an easier way to handle this problem? Getting the plugs out is a PIA. Also......now my reason for asking is I have this same cold start issue on the 1993 FD I now own and getting to the plugs is a real PIA due to the additional wires and hoses on the turbo engine. The 93 ran perfectly for the 20 plus years I have owned it and got the no-start problem this week when the battery ran down and only cranked the motor for less than 10 seconds. Now with fully charged battery it will not start. Hope someone has a short cut so I don't have to contort my arms to get at the plugs.

Sounds like it's getting flooded
The reason you need to remove the sparkplugs is because the engine got filled with too much fuel that can't atomize since it's too cold, so it can't combust and start.
There are some other solutions but I'm not fluent enough in it to feel confident in saying it myself, so I highly suggest you look around for help about "engine flooding" as that's the only reason I can think of for exactly your symptoms.
Some work arounds I've heard are letting it run for enough time to get warm, or hold it at ~3000 for a few seconds and turning then ignition off while still holding it at 3000.
But please do look around a bit to confirm since I'd hate to cause any issues

with an FC, the relay that turns on the fuel pump (Circuit Opening Relay) is right above the drivers right knee, so you can reach under there, unplug it, and crank it over with no fuel. when it starts plug it back in, and you're good
