My f150 won’t start this morning. A few days ago it was in shop; they changed the plugs and cleaned the throttle and 3 part fuel service Mechanic's Assistant: Have you noticed an increase in fuel consumption? And how does the F150 start—same as usual? Yes Mechanic's Assistant: What year is your F150? Its hard to start, 2010 Mechanic's Assistant: Are you fixing your F150 yourself? What have you tried so far? No, we brought it to shop, currently waiting on new o2 sensor, but why won’t it start? Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? No I think that’s it

I don't do the calls, sorry for the delay. Hi Amy, is the truck cranking and not starting or no cranking at all?

It's cranking
Automotive Expert
Ok thank you. This is likely going to be a problem with the cam or crank sensors, possibly a proble with the fuel pump. The O2 senosr will not keep the truck from starting. Also, check and make sure the security light is going out when the key is turned on. If the key lost it's programming, that would keep it from starting as well. Can we check it for fuel and spark?
