I have a 1991 S-10 4.3 L. During normal driving the oil pressure willl drop to zero and the check gages light will come on. If I turn off the engine for 5 - 7 seconds and restart the enging the oil pressure will return to 35-40 psi and stay there for a while. Is this the oil pump or the oil pressure sensor going bad ??
