truck was running fine, went to the store came back parked it, went to leave ten minutes later and it wouldn't start, cranks over fine but won't go.
no engine light is on, plugged scanner into truck no codes found, i noticed while cranking the truck over the oil pressure gage stays at "0". Where is the oil pressure switch located?
If truck doesn't sense oil pressure will this not allow fuel pressure?

any help would be great, thanks!

 

Check the ground connections drivers side battery make sure they are clean and tight. Engine control module grounds there. If loose will cause a no start. If you have external fuel pump mounted on fuel filter housing make sure it is running when bump starter. Is your ignition key gray or black in color? If gray could be bad skim key or module
