in front of the deisel pump the gear wheel is slightly cut/chip mark to the back of it take it out, and place it on t or n (t for turbo n for non turbo) .normal timming is good .If not hand turn until #1 piston is up and #1 cam shaft lobes are not touching cup & shim then set pump to desired mark

My isuzu 4hf1 engine failed to start?

not starting can be from several reasons
cam/crank position sensors failing--wiring -units ---broken timing belt /chain
immobilizer not working properly--flat battery in key fob-- fuse has been removed and replaced
ignition control module failure
injector problems
low fuel pressure from pump not working
the idea is to run the fault codes to get some idea of the area to start checking and work from there

A Isuzu NPR 4hf1 rotary pump timing marks set

Hi. If it has a rotary pump, the pump needs to be installed with the crank at 49 deg BTDC on the compression stroke cyl 1. Mark dot gear on pump with white paint. Line up dot gear on pump with line on pump bracket and install. Remove PRM sensor from bell housing and check if line on pump gear is still lined up with line on pump bracket.
