i have an 01 mazda b3000 and every time, when started cold, the engine supposedly has no oil pressure. now im hoping that its just a faulty oil pressure switch, but now i have a new problem. where the hell is it?!?! all the books and internet reading ive done say its by the oil filter, but im positive that its not. anyone with any similar problem, or knows where the switch is, please help! thanks!:smokin:
