OVP vs FPR ( signs and symptoms) w124 300E
OVP (Over voltage protection)
can restart ?
surges before stall mostly on deceleration?
engine can run(rough) w/o relay plugged?
FPR (fuel pump relay)
No restart?
stall anytime any rpm?
No relay, no run?
If bypassed, will start.
can still hear Fuel Pump preload on ignition on and still have a bad relay?
Am I correct in assuming these symtoms for these components? Please add or change as necessary.
