Have 2 maybe related. Car shut off going 45 I have no spark. Need to trouble shhot that have 12V+ at Batt term on HEI dist. It is a Mallory with a Mallory Coil and cap. Put another coil and cap on nothing. I have the original HEI dist. I can put in but wanted to trouble shoot a little before just replacing parts. Second issue when I tried to restart the car it continued to crank after I turned off the key until I turned off the battery disconnect switch. Battery in truck , Battery disconnect under back bumper, Ford solenoid under hood with purple wire on S terminal. For some reason solenoid seems to latch. If I remove battery side of solenoid and put it back down car will stop cranking until I turn the key again will crank I can remove purple wire and car will continue to crank. It has worked fine for years. I replaced auto column with a manual one. I do not have a switch on the clutch pedal. and no jumper across connector. Must be a N/O switch. Just looking for a few things to check never felt the need for a CSS but maybe it is causing some issue not sure. Thanks
