FORD F-350 ENGINE PROBLEM

1994 Ford F-350 • 160,000 miles

When I turn key engine wont crank
i turned key to on position and bypased starter relay, motor cranks but wont fire
does relay need to functoin to fire?
also, when I first turned on the key I had no power but turned key on/off couple of times and then that problem went away?

It may be a bad ignition sswitch but scan for codes first. You might also try resetting yoru anti theft on your truck that may be messed up. Also check fusilble links at rela/junction box. They have gray to yellow wire one may be making bad contactor most of wires broken in it.
