I would also look at the crankshaft speed sensor, Located above transmission bell housing and firewall in engine bay. Mine was cracked slightly which caused an intermittant start on my car.

Good question. I assume they can't make it quit, and all looks healthy in the doctor's office.

Taking care of the most common causes, tempered with economy, is the correct approach to an intermittent that won't show itself. Start with the 25A fuse holder and its red wire connections under the hood, and the fuel injection relay above the passenger's feet (as they did) and have them be sure the tank pump is operating. Finally, an inspection of the small wires to the Hall effect sensor (distributor) is worth the trouble.

Most try to say, if it happens again, watch to see if the tach needle moves when cranking. The idea is to divide the problem between spark and fuel. But (1) the tach may not respond to the low cranking rpm and (2) your car may not be equipped with a tachometer.

how is your gas mileage? Has it gone way down recently? Wondering if your Fuel Pressure Regulator is dying. Take off the front hose of the Regulator and see if it is wet with gas.

If all they are going to do is replace parts with no diagnostics, it will get expensive. Next time it doesn't start, check for spark. If you got spark, then suspect fuel system. If no spark, suspect ignition system.
