Engine Mechanical problem
2000 Ford Focus 4 cyl Front Wheel Drive Automatic 155000 miles
tried to start the car other day it tried to fire (ruffly) then died, and it wont fire it turns over. It has fire in the plug, and you can hear the fuel pump do its thing when you turn on the key. Any suggestions what to check next
Cranks but no start condition: 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.
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/broken or jumped timing
