85 efi 5.0 intermittent no start. Help!!!!
Ok I've got an 85 f150 5.0 efi and it started out cutting out on me while driving. I have fixed this issue I think. I put a new tfi on it. Along with a new ecm, dist, tune up, coil. I think that's all I put on. It was loosing spark. Not sometimes it won't start but I still have spark. I put a new pump in the rear tank and a new high pressure pump on the rail. I thought I wasn't getting the right fuel pressure. Truck starts sometimes. About the only thing I haven't replaced are the injectors and the harness. I don't know where to go next it won't start today and tomorrow it will start and I won't even touch the truck between tries. When it starts it runs good. It's not making sense to me. Help please
