my 93 died going up slight grade in- 25 degree alaska weather. would like to get it running for trip to east coast. replaced separator filter, lift pump and crank sensor and bled air several times. still can't start. error code 55 shows when i turn ignition switch on, off, on, off, on, within 3 seconds. i'm getting frustrated with it. it's my first diesel. i would appreciate any suggestions to help me get going.
