So I hotwired my fuel pump and then.......
Ok, so as some of you read in my other thread, I was having some issues with a faulty fuel pressure sensor.
So while dealing with that I hotwired my fuel pump.
30amp relay, 8g wire. Wired off the stock relay thing (I know its not a relay, the unit that NAs have but the VR4s dont). Very confident I did everything right.
So I started the car dozens of times, everything was fine.
I drove the car a few miles and everything was fine.
Well today I decided to go for a longer ride. I took it on the highway and then slammed it. It got up to 4kish and all hell broke loose.
My relay thing (the little gold box) started going nuts, it was clicking like mad.
My RPMs were going crazy, My stock coolant temperature gauge started going up and down, the car was very unresponsive and felt like it was gonna die.
So I pulled off the highway and into a lot.
I let the car cool off, checked the engine bay for anything weird. Thinking it was the aftermarket hotwiring relay that was clicking, I removed that and wired the fuel wire to the stock relay. No improvement, I realized that wasnt the issue.
I started it back up and whenever I hit the brakes it really wants to die. I have to slam it into gear to get it to not die. I managed to get it the short distance home (it died a few times) with the relay box clicking like mad.
I know its not the fuel pump because the car idles fine, and when the relay box quits going nuts it will get up and go.
Any ideas? Did I miss something by hotwiring the stock relay, did I overstress it?
Luckily a guy has the stock unit locally for cheap but I really would like to know what is going on. Hoping I didnt damage anything. Doubtful as timing is still true and it never got past 4k.
