Hi. I'm a new owner of an old Ranger. and the biggest problem i'm having with it is trying to figure out why it starts fine in the morning, then once its up to running temp, it wont restart after it sits 10-20 minutes. i get a crank with no start. it'll run on starting fluid until it runs out, so my best guess is that its fuel related. can someone send me in the right direction?
these are the codes ive pulled:
koeo
327 DPFE low voltage
koer (having to goose the throttle to keep it from stalling)
121 high TPS voltage signal at closed throttle
136 HO2s 2 lean
172 HO2s 1 lean
337 DPFE above max voltage
411 "cannot control low RPM"
412 "cannot control high RPM"
should i just replace the DPFE? is that something that would make it not restart?
