not so cold no start.

Sunday it was 20 out and 1009 fired up like a new truck.This morning it was 40 and no start,called boss ,took vac.day and went back to bed til it got light out.I figured GPs,which are 60Gs and pretty new.Or IP finally let go.I have clear fuel line on my return so I can keep track of air bubbles in fuel system.I also have manual GPs.I checked GPs first, all good,hit with just a touch of ether she fired up but was running very rough.Tons of air bubbles in return line which isn't normal on my truck.Turned truck off left elect.lift pump on,no leaks on lines or IP?Then I thought the only thing I did to truck on Sunday was fuel it up,so either bad fuel or I over tightened fuel cap.I opened fuel cap,whoosh of air rushes in,restart truck no bubbles in fuel return.I wasted a vacation day because of my fuel cap...Im looking for a rebuilt IP,just hope it lasts til I have some time off.This is my only vehicle currently.Do you guys think the restriction on the fuel tank made the IP suck air around throttle shaft seals?

I think you're lucky you didn't blow a head or intake off with the ether(knowing your GPs worked.

Thanks doghead,I have manual only GPs and gave it plenty of cool time before the ether.I hated to use it.What do you think about the air in system,then lack of it after releasing vacuum on tank.

Bad cap or tank vent? IDK

Its not possible to over tighten the fuel cap. Could be the vacuum in tank is sucking air into the fuel system. My leak was the fuel pressure sensor in filter base, there was no visible fuel coming out. Next time it's running, crack the cap to release vacuum when you've shut down for the day. If it fires right up in the morning, start looking for that leak.

Looking at my new tank and sending unit sitting in my living room the only vent I see is the one that is in the throat of filler tube,so must be cap,Ill either drill small hole in cap or continue to run with cap loose.Thanks for the input guys.With cap loose it does start great again and runs well.After I replace IP Ill tighten cap to see what happens,Im wondering if IP sucking air around throttle shaft.
