Gauges Installed, Questions
finally got my gauges installed. i used sunpro sport St gauges.
- everything works good except my fuel pressure gauge. when i turn the key, it goes backwards to 100 and stays. i checked all my connections and they seem good. besides, the other gauges work fine. didn't know if anyone on here had a similar problem. thinking maybe the sending unit is not working right.
- my transmission sending unit was too long so i couldn't hook it up. going to contact sunpro on this.
- sitting in a drive through last night, my temp gauge would run up to 210. driving down the road it would stay at 198-200. is 210 a problem. it was maybe 80 outside.
- running ID extreme street tune, 1400 on the egt gauge is easy to hit.
all together i installed 5 gauges (boost, egt, trans temp, coolant temp, fuel pressure).
i will get some pictures when i have a chance..

100 is maxed out, so what do you mean it goes backwards to 100? Mine stay at 62psi when I turn the ignition off. Next time I turn it on, they cycle down to zero and then come back up to whatever they are reading. If yours doesn't behave this way you have a wiring problem, bad sender, or possibly a stuck radiator. To diagnose the sender, plug your fuel pressure wiring into your boost sender (if they are the same, ISSPRO uses the same sending unit for both). If it reads the correct boost pressure your wiring is correct.

More than likely you have a wiring problem somewhere. Positive and negative switched or signal from your sender connected incorrectly. Oh, and zero is backwards, 100 is forwards, that confused me initially.

Wait, so it goes negative past zero and settles to 100? My ISSPRO gauges have a pin that prevents movement past zero. Or do you mean clockwise to 100?
