Engine Performance problem
1998 Nissan Sentra Front Wheel Drive Automatic
----------------------------------------------------------------
While driving, car jerked; turned AC off. Drove another 20 miles no problem. Got off Interstate, car stalled, wouldn't start. Coasted for 100 yds, then turned engine over; started. In jerking motion, drove 4 miles home. Got home, car will not start anymore. Checked fuel pump and replace gas filter, ok. Checked all fuses.

Could it be the fuel injector or fuel injector pump seliniod?

To determine if its a fuel or igntion problem do below

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself,distributor pick-up,control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
