Hard Start
Please help! Son in Law has a 1985 F150 with 5.0L EFI engine. Starts OK when cold. Hard to start when warm after sitting for 10 or 15 min. After starting will start OK consecutively. New plugs and wires and ignition module. Timing was set OK. Fuel problem? Thanks

Pull the codes, check the fuel pressure with a gauge, and test the coil by the Haynes procedure.
