NOTE:
INSTALLATION OF THE GLOW PLUG MODULE (FOTZ-12B533-A) WILL NOT DECREASE CRANK TIME BELOW THAT
ACHIEVED BY ANY OF THE THREE METHODS JUST DESCRIBED.
The resistor bar kit and the electronic glow plug control module cause the "WAIT TO START" light to remain "on" for a longer time. Installing them
will allow the customer to follow the starting instructions outlined in the Owner's Guide, 7.3L Diesel Supplement and bring the starting time to a more
acceptable level.
If the hard starting condition continues, perform the following checks to rule out other possible causes of excessive cranking time. Refor to the 1988/90
Engine/Emissions Diagnosis Manual, Section 20, for service details.
OTHER ITEMS TO CHECK
^
Make sure that the battery voltage is a minimum of 12.5 volts. (Reading taken at either battery.)
^
Check the voltage supply from the glow plug control module to the glow plug system. The minimum value should be 7 volts. If there is less than 7
volts, check the fusible link and/or service wiring.
^
Make a resistance check on all the glow plugs (0.4 - 0.6 ohms). If they are not within specification, replace them as required.
^
Make sure that only good quality fuel is used.
^
Make sure that there are no fuel system suction side air leaks.
