In addition to my other problems (check my other post in this forum- "sell my 7..." please!!) I am also getting a code 51 sometimes
It is for the fuel pump resistor relay. I can't find anything on testing it or whatever. The check engine light doesn't come on, it ony comes up if I check the codes.... and only once in a while.
Another question- I have the ACV disconnected, so I always have a code 30, and 33 when I check them. With this disconnected, shouldn't the chekc engine light come on all the time?? It never does. (unless I disconnect the TPS or something)

Anyone know about the fuel pump resistor relay, what it does, and how it could affect the engine? (relate to any probs in my other post?)
I chekc the FSM- couldn't find anything, maybe I'm just blind.

Thanks

 

I don't think non turbos have those... ?? they are located behind the pass. side headlight.
