Do you have a lift pump pressure gauge? If so what's that look like?
No I don't, just fuel rail.Do you have a lift pump pressure gauge? If so what's that look like?
With my truck running?FCA would be my start since your pressure is going whacky. Try unplugging it and checking rail perssure?
It went straight to 30k...new FCA?Unplug it, start truck and watch gauge. Should make somewhere around 20k if it's good. Shut it off once pressure levels out.
Well I've gone all over town and couldn't find anyone who keeps an FCA in stock, dodge house said it would be until Wednesday so I'm borrowing a vehicle from a family member for my trip and just deal with that after the holiday.Not necessarily. I'm not sure there's a way to definitively rule an FCA good or bad. Sounds like its regulating pressure at idle (pressure only spikes with it unplugged), which it's supposed to do. You can try taking it out and shaking it to see if it "rattles". replacing it is about the only way to make sure you have a good one as far as I know. You can also try checking all electrical connections.
