Engine Performance problem
2005 Pontiac Montana 6 cyl Front Wheel Drive Automatic 100000 miles

vehicle spontaneously overheated on the highway at speed, then engine shut down. Battery went dead almost immediately. After cooldown (nearly 2 hours) and a jumper cable connected, vehicle cranks but will not start. Have checked all fuses (inside and under hood). Can hear fuel pump come on. Can hear efi system pressurize. Once jumper cable is connected, all dash lights work as normal. No strange messages on dash.

Vehicle cranks but will not start.

Do basic stuffs below: Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 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
