Question about 1991 Ford Probe
Sounds like fuel is not getting to where it needs to go to run. Changed out the fuel pump and the fuel filter . when that didn't work Changed out the fuel pressure regulator. Can hear the fuel pump working. What else can be the problem?
Check your fuel rail on the intake. if you are not getting fuel there the blockage is in the lines, if you are getting fuel there then it is your injectors clogging up
