No, I don't lick fish.
Ugh... I actually meant to say substitute, but that works too.
Since OEM is Bosch, I'm going to say no. Go with the Bosch, you'll not be disappointed.

So I've been racking my brain on why my fuel trims are now negative, new injectors, did a fuel pressure test the other day, was poking around my ODB2 scanner and forgot it does the mode 6 tests, I'm failing TID:11 CID:01 for the upstream O2 sensor, no CEL but I did run it with the MAP sensor, and leaky injector problem for a while. Would that be enough to gunk up the new(as of last year) O2 sensor? Failing with a value of 19, where the Min is supposed to be 48<-whatever that means... Is this enough info to say go ahead and replace it or is there a way to clean it?

Are you able to capture a graph of what the O2 sensor is doing? If you had a leaky injector for a while, a fouled sensor I would think report rich incorrectly since not much oxygen can hit it, but I can't confirm that.

Not entirely sure what the 'value' is, is it an abstracted voltage?

Thanks. Having the longer to start when it sits problem. When running fuel pressure is right on spec. Pretty sure no leaking fuel injectors or lines. So thinking the check valve thing on top of the pump. You can buy the check valve but doing all the work just to replace that seems stupid. Figure just replace the whole assembly. The Mopar pumps go for about $330 online. While I have no intention of doing the repair anytime soon figure some day I might. If it would have been a good idea to use the Mopar instead of the Bosch one I would have grabbed it for when I decided to do it. Just when till if and when and then buy the Bosch one.

Stater isn't getting enough volts to start
I've check the battery and the starter and they are both good. I'm starting to think its something electrical but I'm not sure what! Any ideas?

Yeah, it's a pain I know. For now, just do the "poor man's prime" by cycling the key twice before you try to start it. That'll get fuel further up the line and just about into the fuel rail to decrease your starter time.
