This article supersedes TSB 04-22-8 to update Figure 1.
Some 7.3L vehicles equipped with the glow plug control module (GPCM), may exhibit a hard start or no start condition. This may be due to the GPCM connector.
A new GPCM connector service kit, available for the 6.0L engine, can now be adapted to the 7.3L engine. Refer to the following Service Procedure.
Inspect the GPCM connector for pin conditions such as; pin fit, pull out, bent, corrosion, etc.
If a concern is found, replace the GPCM connector with the kit. The kit contains a replacement connector with pigtail to be spliced into the existing harness. DISREGARD THE INSTRUCTIONS INCLUDED IN THE KIT (WHICH ONLY APPLY TO 6.0L) AND REFER TO FIGURE 1 FOR WIRE SPLICING.
If no concerns are present, proceed with normal diagnosis.
