My car has been out of commission the past 2 months as I did cooling system work. Today I got the system buttoned up enough to try and run/exercise the engine. But it will not start! I have good fuel pressure, good spark at all cylinders, good compression at all, and no air obstruction. No reason to think the timing went awry while just sitting. What could it be?? The one thing I’m noticing is that when I reach down to press the button on the bottom of the starter solenoid there are some small sparks popping up at one of the joints in the throttle linkage. So I’m thinking some kind of electrical short? But I have 12V across the coil (at least when the ignition is on and I’m not cranking–haven’t got the hands or an assistant today to read the multimeter across the coil as I crank) and spark at each cylinder (as indicated by a typical inline test light) so I can’t imagine the short is ignition related/ignition defeating. Maybe the sparks are just arcing from me touching the negative solenoid to the positive ground (since throttle linkage is bolted to car and is presumably ground). Long shot but anyone ever have a similar experience? I suspect I need to just test every bit of wire in the ignition system bit by bit (already prodded the works with my multimeter for a hour today). I sure hope some creature did make a nest/have a chew while the car was dormant!
I should add that the last time I ran the car in my driveway before the dormant period I noted that the generator stopped charging the battery. The reason for this was the fan belt gave up the ghost. Obviously I installed a new one while I have the radiator out and the cooling system apart. And even if I were to be having generator trouble now surely the car would run at least briefly off the battery (and jump pack I also attached on to give it extra cranking boost). But I get nothing, not even a putter or a cough right now.
And I will add, even though the fuel system is all newly redone and I’ve checked I have proper pressure in the line, I gave it a little shot of starter fluid into the air intake just to rule out a fuel issue. I don’t like using the stuff and do so sparingly but a little shot of it down the intake makes me feel confident that there’s combustible stuff in the cylinders! And finally, the start is perfectly good and cranks the engine vigorously without delay or hesitation when I press either the start button or the start solenoid bottom button.
