whether test should be performed while
cranking or running. Familiarize with proper
speciications and any unique testing
procedures, and follow recommended
procedures for removing and installing
injectors.
1 Put vehicle in neutral or park, and set
parking brake.
2 Thoroughly clean area around each
injector to eliminate any chance of dirt or
contamination entering engine.

then stop cranking. If running engine,
note length of running time until
maximum pressure is reached.
9 Record cylinder number and peak
compression value.

and all remaining cylinders. Be sure to
crank engine same number of strokes
and to record peak compression value
for each cylinder.
