I have a 1998 gmc jimmy 4.3 v6 with 137,384miles on it. Hard to start can turn key on and off several times it will start. We put on mass air flow sensor changed all plugs and wires, rotor, distributor cap, ignition coil, map sensor, fuel filter, check fuel pressure it's 35-40 psi, put on a computer and didn't find anything. PLEASE HELP US we don't know what else to do.
