Having trouble with my rb25det s1 in a 33. Changed plugs, coils, cleaned and soldered afm, fuel filter, and tore apart the wire loom looking for a bad wire. Next up is replacing the ignitor. Is there a way to test them using a multi-meter to check it is working properly? If so, what are the specs? A new one cost $200ish and I'm tight on money. I'd go get one if I knew they would let me return it but they won't allow you to return electrical components. This is the one I have.
