No fire in driver bank

[bdydmg]

hey guys,,new to the site,,I have an issue with a 97 7.3..

was running fine,,shut down and started a few hours later an ran like crap.
Started running some checks..
first off changed fuel filter,,no change.

Driver bank exhaust manifold is stone cold after its been running 5-10 min compared to pass bank with is very hot to the touch..All cyls on driver side seem to be dead.

checked gasget plugs and injector harness and all check good.

I'm told there is a injector module but not sure where it is or how to check it..

seems odd its all on one bank.. thanks..

Did you take the valve cover off and look at the harness under it or just where it goes into the valve cover??

[bdydmg]

I tested the valve cover gasget and both wire harness under the valve cover..It all tested good with no shorts or bad connections..

I also poked around in the wire harness leading to the valve cover gasget..I was thinking maybe a short was to blame further down the harness.Can't seem to find the wires that lead from the valve cover gasget to the wire block on the fender well..But I don't really know what I'm looking for.I don;t have a wire scheme.

Almost sounds like it has to be the wire harness under the valve cover...how did you test it to conclude it was good?

[bdydmg]

ohm meter on both harness under valve cover and gasget.

I assume yellow must be ground??It was the only color that had exposed wire where the yellow leads come together and go into the connector..Ground would be the only wire I could think of where it being exposed would be ok.

I'm willing to bet that if you take the vavle cover off and look at the connectors you will see where it is coming apart.The plug may be plugged in enought to give a good ohm reading but not plugged in enough for the injectors to work.

be NO exposed wires.

I have it apart now,,Best I could tell by looking at it the connectors looked good aside from the yellow wire being exposed where the two wires come together..

what are the odds both harness in the one side going bad at the same time?
The harness is only 28$ each,,so maybe i'll give it a shot..

just an fyi
You are wrong..the yellow wires are ALL exposed where they splice together on new and old harness....

and an update,,turns out to be the module for the injectors..All fixed,,thanks for the help..
