Electrical problem
1993 Buick Regal 6 cyl Automatic 187000 miles

i noticed a few times that the car wouldnt crank on the first try but it would always crank on the second try. Then it began cranking up only occasionally leaving me stranded places. It also began cutting off on me in traffic. Everytime I would take it to the mechanic it works just fine. Since these problems arose, ive replaced the relay switch and the battery. Now, 2 weeks later, it will not crank at all but it continues to turn over. What could the problem be?

Lets do below for a start to determine if its fuel or spark related issue and get back with some results

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
