My 93 is flashing KOER error code 998. I did some forum searches with little success. Does anyone have any advice?

Many thanks sir.

Still haven't fixed the problem but its only a matter of time so no worries there. But if anyone has a diagram/photo of the proper installation for the straps I would appreciate it.

This was my thinking as well. The half ohm could be connection related to the probes or maybe meter offset. Unless someone has other option(s) I think Ill slide the tank back under the truck, plug the pump in an run an alternate ground and see if the pump runs then.
