1989 Ford Escort

Fuel delivery problems i have replaced the following parts fuel pump,sending unit, fuel lines, filter and injector and fuel pressure regulator still no fuel to the injector any suggestions???

Have you changed or checked the fuel injection fuse under the hood. It's in a box close to the battery.

Have you checked the inertia switch? I'm not sure where it is in your car but the owner's manual will tell.

The inertia switch is behind the plastic panel on the left side of the trunk. There should be a black rubber plug in the panel that you can remove so you can reach in with your finger and reset the inertia switch. I had an inertia switch go bad once on my '88 Pony and it had to be replaced, because it would decide at random when it was or wasn't going to start. The no start conditions were usually wet or cold weather.
