My 1981 242 B21F K-Jet will not start. The problem has been progressive - a month ago it very rarely would not start, and by sitting and waiting a minute or two, I could start it again. Now, it will not start at all.
Every no-start has been the same - the engine cranks over rapidly, the tach jumps slightly like normal, and the car simply will not start. If it would not start with the key, I could roll start it successfully, but now I cannot even do that. When the car did decide to start, I could turn it off and restart it indefinitely, but if I left it and came back, the odds of it starting were 50/50. It doesn't seem to matter if the car is warm or cold. Occassionally, the car will *almost* start the first time, and then refuse to start from there on out.
The engine runs fine once it starts - it has the same smoothness and power as my dad's 1981 242, which has no problems. It never cuts out or sputters, although it does run VERY roughly when cold - I attribute this to a bad thermal time switch, cold start sensor, or the fact that the car has 300,000 miles on it. (or any combination therof) Would these bad sensors cause this no start?
Otherwise, I have tried the following things:
-replaced fuel pump relay with brand new
-checked fuel pressure regulator for gas or smell of gas (none)
-checked for spark at all plugs (yes) and at coil wire (yes)
-replaced spark plugs
-replaced fuel filter
-checked for gas flow at filter intake - there seems to be more than enough pumped out both when i first turn the car on and the pump primes, as well as when I crank the engine.
-checked the compression (163/163/170/165)
-replaced the coil/plug wires
Also, the starter occassionally grinds when I start the car (maybe 1 in 10 times), which I attributed to a 300,000-mile-old flywheel (ring gear). I'm fresh out of ideas, and any suggestions are greatly appreciated, as I can't afford to take the car to a mechanic right now.
