MITSUBITSHI WONT START

2003 Mitsubishi Carisma • 4 cylinder 2WD Automatic • 10,000 miles

What can I do to get back my mitsubishi carisma 2003 model back to what it was after showing me pressure fail code and I have replaced the fuel pump with a new one. Still it wont start?

It takes 3-things for an engine to combust-compression, fuel and spark-

Next time it refuses to start don't wait for it to make up its mind-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, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, 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,cap and rotor,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing
