Question type: Maintenance & Repair

We already changed the oil sending unit on the side of the block and we have already
done a manual oil pressure test on the top of the filter and we got a good reading, we are
getting oil to top end on rods and we have plenty of oil in pan...still not getting oil pressure
on gage in cab.

try unhooking the battery, sometimes on many vehicles when changing the oil or a simple part will mess up the computer at times. if it still does not fix the issue you are having then you right away need a oil pressure regulator switch relay. its in your fuse panel next to the battery. labled oil pump relay or pump relay.

My Dodge diesel 6.7 was running good and when I came home from work, shut off and 2 hours later I went to start and the engine turns over, but will not start. I thought it was a fuel problem, so loosen injector and turned over and had fuel. I tried to run engine analyses and nothing. It appears there the electrical has shut down, but the engine still turns over. Are the fuel injectors electrically pulsed or by pressure form pump? The only thing that come up is check gauges. No engine light at all. 2 Answers
