my buddies 250 6 cyl
what could it be if i get no oil pressure at the sending unit? brand new oil pump (could be a manufacturer's defect) what else could it be. i tested my guage by hooking it to my air compressor @ 60 psi. the guage reads 58-59 psi. i know its not the guage. i used new copper line to the guage and tried the plastic line after the copper line seemed not to work. with the car running the guage reads 0 psi on both tested guages (have 2 checked 2) on both types of line. the oil pump drive (kindergarden fat pencil lookin' thing) is brand new. we spun it with a socket on a drill. shot oil up through the distributor hole all over my buddy. it pumps oil out of the sending unit hole when the sending unit is removed. it doesn't seem like 60 psi though. any suggestions?
we also tried to diagnose the oil "idiot-light" we hooked up a test light and bridged the wire to ground. the test light glows but the oil light stays off. we hooked a multimeter to see if it varies the resistance based on pressure but the ohm meter never swayed. we tried all of this with the key in the off, start, and run positions. no oil light. my guess is that bad boy's flat burnt out. any other suggestions?
there was a plug in the back of the motor. when we first started the motor a couple of months ago, we pumped a whole bunch of oil out on the ground and had to take the motor out to find the leak. there is an access hole between the flexplate and the block. we plugged it and put the motor back in the car. now there isn't any oil leaking out of the motor. as for the oil coming out of the distributor hole, im not sure. i wasn't in the garage for that part. i'll ask my buddy again. i was thinking about taking the valve cover off and letting the motor run for a minute or two. if i get an oil shower, i can guess its oiling. the fact that i cant get an oil pressure reading from the sending unit hole is quite concerning.
any help is greatly appreciated
