rb25 cts problem

[davidg01234]

My rb25 won't start when it gets warmed up. But if I unplug the cts it starts right up. Tried replacing it and the same thing happened. But if I plug the cts back up after I start it, it runs fine then. Did I just get another bad cts, or is it something else?

Two wire CTS? Operates with the same signal ground as many other sensors, you may want to check the wiring point to point and then just try another sensor. I have nabbed a few from junkyards.

yup the one for the ecu not the gauge. ive already tried another one with same results. BUT i think i found my problem, im thinking its the battery because if i jump the car off with another car, itll fire right up with it plugged in.
