67 Mustang
289 4bbl
Just got it back from the shop and now the oil pressure is reading nonexistant. The oil is full and I tested the gauge by grounding the sensor to the engin block, it moved. Driveing back from the shop and a little around town seemed fine but I'm concerned. Are there any tests I can do besides pulling out the whole oil pump to see what the problem may be?
THanks for any suggestions.
