My buddy was driving his 98.5 and it suddenly died. He put a new lift pump on about a month ago because changed filter and would not reprime. A few days ago he instaled a edge juice w/monitor and drove it for a couple of days itll it quit. He got codes p1693 and p0237 there is no fuel getting to the injectors but 14 psi at the pump. Any help is appreciated Thanks

 

P0237 TC Boost Sensor Circuit Low Voltage

try unplugging the Edge and see if it starts.

sounds like an injection pump(VP44) to me.
