got a 93 escort wagon. 1.9sohc. it was running fine then things started going wrong. first the heater core. i replaced it and the thermostat the waterpump and some hoses. also when i put the new pump on i put a new timming belt.so motor is timed 100% perfect. then is started getting hard to start. i thought it was a fuel problem due to a bad fuel pressure reader i got from autozone.so i replaced the fuel filter the pressure regulator the vacume line going to the pressure reg and ended with the new fuel pump and fuel pump assembly. none helped. just made me broke. a few months later the car stoped completely. i replaced the crank sensor and it starts. i have to keep the gas to the floor or pump it and then it would start. after backfiring out the intake and exhaust it would start and run very very baddly. then i woul hold it to a high idle and it would clear up for and drive fine. if i turned it off and started right back up it would start right up and run great. but if i wait ten min it would be hard to start again. after driving it a week id died in a parking lot. there it still sits. it just cranks and backfires from all ends.WHATS WRONG

 

anyone have a lil idea
