cut off towed in restarted with limp in mode p0087 code
Posted to Technical Discussion Forum on 4/1/2025 4 Replies

Scan tool reads extremely high fuel pressure ( 40000 ) psi the ecm tries to lower the pressure but cannot . the car has a new fuel pump and pressure regulator if you unplug the fuel pressure sensor it goes to 4500 pounds on the pid. The only way they sell the sensor is with the pricey fuel rail which is a bugger to replace. any one run into this issue? when you first crank it the pressure starts out at around 2k and climbs up to 4k Don't know why the low pressure code. the low pressure fuel pump is exactly where it should be.
