my 93 d150 5.2 has been acting funny. i have always started it by putting the key forward,for a second or two until the fuel pump stops,then start it. yesterday i just started it by turning the key right to start position without waiting for the fuel pump to stop.
it was hard to start,cranked over fine,just keeped cranking for a while.
when it did fire up it was a little rough running for a minute or two.
anyone know what would cause this?? thank you
