Code 17,18

[David Brady]

My blue tag pump has 109K miles that I have put on and total 162K on the truck, evidently the pump was replaced before I bought it. This morning it stalled at a light and when I restarted it went into I believe "backup fuel" mode with very little power. It came out of it once when I topped off the tank and did okay when I stopped and got a new filter, but slipped back into the low power mode a few minutes later. Checking codes at home I have 17,18,35,36. I checked the fuel flow with my auxilary switch and at the pump I had good flow. Does this mean the inside of my pump is trashed and ready to replace? It is hard starting and gives a good rattle when it finally takes off. Has anybody seen these codes for something other than destroyed rollers? I put a remote FSD on about 8 months ago and 10K miles. Thanks,

Thanks Gapper,
I have a book and I looked at the codes, but what I'm wondering has anyone recovered from these codes and gone another 50K. From my research on the site it doesn't appear likely and I just got a new pump. Thanks,
