Coming home from work my car just shut off without warning. Changed the Battery, alternator, spark plugs and Block sensor and Harness. Turn on for a few seconds then shut off again. Tried to restart it but with no luck. Lights, horn, radio is working fine. Not sure what it can be at this point. To many people are telling different things.
There are many things that can cause the vehicle to stall/not start. The 2 most common are lack of fuel and lack of spark. Possible fuel pump issue or relay/wiring to fuel pump. This can be checked/ruled out by performing a fuel pressure test. Another common issue with this vehicle for stalling/no start is a crankshaft position sensor that will cause an ignition spark failure. Have the codes scanned as this sensor will usually set/store a code before you throw any more parts at it
Dirty egr valve, ignition switch, my car kept cutting off while driving and it was the ignition switch, when my car would not stay running it was the egr valve. To test you ignition switch use a remote start if it stays running then switch is bad if it cuts off then not switch. When my egr valve was dirty it would stay running when I pressed on gas pedal. Make sure vehicle is in park when you try this
