When cold it will start. You kill it, go in a store and out it will not start, you will have to grand on the starter to get it to start. Now this is what I have replaced, temp heat sensor, oxygen sensor, plugs, wires, rotor, rotor cap, disp cap, coil, fuel pump, fuel filter. Tested battery, fuel pressure 48lb, alternator is ok, What have I missed

Next time it refuses to start don't wait do below immediately to determine if its fuel or spark problem.

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
