My 86 Cadillac Fleetwood with a 4100 motor just stopped running one day. Took it to a mechanic he said that the cam walked, gear ground on distributor. He replaced the gear and cam button. Drove it for about 100 miles and it just stopped running. There have been no engine warning issues. It just stopped running. It turns over but doesn't start. Any idea what it could be? THANKS!

Do below:

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
