REFERENCE INFORMATION
Check the rubber return line from the injection
pump to the steel tubing return line.
If the rubber line is not clogged, go to 01,
page 2-116.
If the line is clogged. replace it. Start the
engine and see if it stays running. If it
doesn’t start or stay running, return to Ji
and continue testing. There may be another
fuel system fault preventing fuel from
reaching this point.
If the cold advance solenoid is getting power,
the only possibilities that would keep the engine
from starting are that fuel is not reaching the
cylinders due to a fault in the high-pressure
side of the fuel system or nearly all the cylinders
have very low compression.
It is unlikely that
all the cylinders would lose compression at
the same time, but you may want to run a
Compression Unbalance test (STEIICE-R
Test 14) to check this.
