93 Ford F150 XLT 5.0, 5 speed manual trans, 300k+ miles, well maintained, 1 owner. Engine has good spark, turns over well, 40-42 psi fuel pressure at the rail, new air filters, wires, plugs, cap rotor, pcv and fuel filter. Fuel pump replaced last year. Will not catch and run, turns over like not getting fuel, but, can spray a short burst of ether and the engine instantly catches and goes into a high idle (2000-2200 rpm). Engine rpm is constant, does not vary. Can unplug the idle air solenoid and the engine dies. Have checked for an external vacuum leak, checked the booster for a leak, sprayed around the intake manifold with starting fluid and carb cleaner and get no indication of a leak. I suspect the idle air control solenoid as it is the original. Any suggestions?
have the same problem?
