Cold starts after the car has sat for a long time is brutal for the

anyone installed an oil pressure safety switch ( ~10lb setting) in
series with
the ignition circuit or fuel pump in order to ensure oil pressure
before it
fires?
>>>Yes, it's called your "right foot".
Unless your car is extraordinary, normally cranking it cold without
giving the throttle at least a token pump will result in endless
cranking but no starting. My GT350 would start right on the button in
1/20th of a revolution if I pumped the gas once before turning the key.
When it sat for awhile, my technique was to just turn the key and hold
it, watching the oil pressure gauge as the engine turned over. As soon
as oil pressure came up, one pump and VAROOM. That's with no choke.
My Pantera has an electric choke, sits for eons without starting, and
normally has to crank a fair bit with a few judicious throttle
applications before it will light off. What about yours?
