1997 GMC Sierra SLE
The fuel pump has been changed now this
morning(weeks after) it was starting hard cranking
for a while before firing , third time driving it it tool
longer while cranking to fire and I had to rev it to
get going , now it won't fire for me , oil was dry so I
added 5w30 oil 2 conventional one high mileage
and 2 16 oz 10 w 30 conventional oil in total rpms
have been messed up (you have to feather the
pedal with the break at 1000 rpms to idle) any way
to get this thing fired up started for me? Been at
this since about 3pm now 7:22 pm just ready to get
it going again
