So I'm not entirely sure if this is even an issue or not but it is something I've noticed. It first came to my attention after installing the high idle mod, although I can't say for certain that's what caused it, or if that's when it started.
Anyways, my issue is that I no longer get a 'prime' when turning the key and waiting for the WTS light to go out. Before I would turn the key, hear the pump prime for about 5 seconds, or just long enough to build to about 15-17psi and then cut off, shortly after the WTS light would extinguish and I'd fire her up. I'm not sure if it's just getting colder outside so its harder to prime or what. I did bump it and it ran through the typical phase of priming for 30-45 seconds or whatever it is. No noticeable drops in PSI across the driving spectrum.
I know the obvious fix is to get rid of my 'junk' lift pump, which will probably be replaced with a fuel boss soon, but for the time being, is there anything else I can check? Or is it even an issue?

***EDIT***
I think I've solved my own problem, should've done some more reading before posting!
I forgot I just had my truck flashed to enable high idle so that's probably why my lift pump only 'primes' for a second or so now.
If I'm off track on this and it could be something else, please let me know!
