I am working on a '99 E350 with the 7.3 PSD...

In the process of changing injectors/turbo/pump etc I found a broken wire... the wire is grey with a red tracer and has a single wire connector about 3" from the break. The wire is on top of the engine near the filter bowl, but I cannot find the other end.... I looked at a bunch of schematics and did a continuity test, I have continuity (with ~58 ohms resistance) between the plug and pin #37 on the PCM. My pinout chart has that labled as the "fuel line heater", but both of the wires going into the fuel bowl are intact...


Any help??

EDIT - resistance is 58.5K ohms. There is no continuity between the broken wire and the IAT sensor or the injector module...

 

it maybe fuel bowl heater. if I remember correctly from my buddies psd

 

Could be the fuel bowl heater... Or the water sensor... both use a single wire conector.

 

the only plug going into the filter housing is a 2 wire plug... and it seems to be intact...

The wire is a light gauge wire...


The van in question is a early '99 (non-IC)

 

None of the vans have IC's...

Bottom of the fuel bowl or on the side there is a second wire that goes to the water in fuel sensor... I dont have a bowl in front of me to jar my memory...
