SOURCE: 98 Escort Hard starting when hot
sounds like a dodgy mis reading of a sensor caused by electrical resistance which is turning choke on and flooding engine.know the fault but without car in front of me its difficult to diagnose,could be auto choke sensor which is on right hand side of cylinder head ,but not sure.best is probally dealer have you tried spark plug gaps ??25th although this would cause problems with cold starting not hot starting but its worth a look

Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

Blair, I would take a look at he TPS (throttle position sensor) located on the throttle body. In other words, it sounds as thought sensor when heated is changing its value to "open" or "shorted".
If the car starts OK when cold, use a hair dryer to heat the TPS when the engine is cold to see if you can duplicate the problem.
Also is the a service engine light on? Codes?
If you have a "digital volt/ohm meter" available you can read the variable resistance of the sensor when the problem occurrs to determine if the sensor is defective.

If you have fuel on the vacuum side of the reg, that means the reg is leaking,causing a variaty of drivabiliy problems. Replacing this reg is very straight forward. Just add a little lube to the O-ring on the reg before installation. Good luck.
