Re: '95 E-150 hard starting when parked on hill

When cold is the time it will act up the most. As the engine is idling rough, spray carburetor cleaner near the intake manifold gasket sealing area and look for the SFT readings to drop pinpointing a gasket leakage area. Check the Red wire at the fuel injector connectors for a possible voltage drop issue and service the engine harness connection or splice as needed. Check fuel pressure readings. Fuel pressure should indicate a reading of 30-33 psi at idle and increase to 40 psi when the vacuum line of the fuel pressure regulator is disconnected. When power-braking the engine, the fuel pressure should rise if the vacuum line at the pressure regulator is connected because of the drop in the engine vacuum. If the fuel pressure does not increase under load or is low with the vacuum line disconnected at the fuel pressure regulator, service the fuel filter for a possible obstruction and replace the fuel pump as necessary.
