OK, after changing my GPR & EOT senser and ringing my glow plugs (which were changed to new Motorcraft about 35K ago), I'm frustrated. Also ckd the ground strap for tight at passenger firewall. Can't seem to find a picture on where the fusible links are for these circuits. Or maybe a fuse? Not great at figuring out how to see what might not be grounding for the PCM to light the glow plugs so I don't get the bloody SES light.
Any help appreciated.
Are you sure you have the GPR wired correctly? There are pictures and diagrams in the 7.3L PSD Tech Folder.
I pulled the fault codes from the PCED Ford Service Manual
P1391 GP Glow plug circuit low input, bank #1 (right) Open/short/miswired circuit, faulty relay, glow plugs
P1393 GP Glow plug circuit low input, bank #2 (left) Open/short/miswired circuit, faulty relay, glow plugs
Image from wiring diagram.
No real location information for the fused links other than this...
