How to diagnose no start no crank?

Why does my car not start when I spray starter?
There’s something wrong with the fuel pump. If you cycle the ignition switch just one time, the fuel pump should pressurize the fuel system in a second or two, and fuel should spray out the Schrader valve. I think he was just pressing down the shrader valve to see how much pressure was there and not actually putting a tester on it.

Why does my car run but wont start?
Changing used spark plugs. A quick method to check if there’s an issue with the fuel supply is to spray starter fluid into the air intake hose.

What should I do if my engine won’t start?
Not sure if your truck uses one though. But if it does, and it is part of a fuel return system which returns unneeded fuel rail fuel back to the tank, ask your mechanic to remove the vacuum hose connected to it (which goes to the intake manifold) and check for any fuel inside. There shouldn’t be any.
