Engine/Transmission (1998.5 - 2002) Ran lift pump dry - ECU code 0230

[DonS]

Replacing the fuel filter yesterday, I neglected to refill the canister or bump the starter before attempting to fire her up. I realized my mistake when it started and ran for about 2 seconds, then died.



I bumped the starter a few times and verified that fuel was spewing out of the banjo bolt at the injection pump. I tried to start, but my batteries had (by this time - about 30 seconds of cranking) been depleted.



After replacing the batteries, it fired right up. However, now I've got codes 1693 and 0230. I realize that 1693 is a companion code, but 0230 is related to the lift pump ("Transfer Pump (Lift Pump) Circuit Out of Range", according to my service manual).



After my initial cycle-three-times, the check engine light no longer comes on, and the truck seems to run just fine.



Question: is the 0230 code just an artifact of running it dry? Should I be worried about it, or should I just ignore it until I see it again?

At our plant we run natural gas compressors. On the supply side there is a mercoid that monitors vacuum, on the pressure side there is a high pressure mercoid. (I'm building an analogy here) No gas, alarm/ shutdown. (Vacuum) Over pressure, alarm/ shutdown.

The PCM may monitor high and low current to the lift pump. The code may have been set because of low current draw from LP (low pressure on pump) or lack of pressure at VP pump. It seems like this code would only occur when engine is running.

Maybe someone who has run out of fuel will chime in here and confirm my theory. I'm just guessing. I would ignore it, the truck just spanked you for doing something it didn't like. Mike
