GRRR im so Fin frustrated with controlling a electric pump. I have gone the oil pressure switch to control the relay and they would last a year or so and die, now I have gone to having it off the alternator and now I have had a string of alternator issues. My next thought is control the relay off the idm power, is there anybody else that has done this? it either that or i was thinking about swapping to a SD pcm just to have the pump control. I have had the last alternator last about a year and this one lasted 3 months. the one before that lasted like 6 or 7 years.
