Oil Pressure Gauge Not Working

[Hheppy 9 1 Cars]

I just need to check with some of you seasoned campaigners that I am going in the right direction here.

 

Gauge shows no pressure when engine is running, Oil level is fine.

 

switching on the ignition, the red light on the gauge comes on and goes off once engine has started so it appears I am looking at electric rather than anything else here.

 

Should I just replace the pressure sensor behind the manifold or are there some other electrical connections to check first? The terminal looked ok when I checked on the sensor, no corrosion, so wondered if there was something else to check first.

 

Also, I do have a very small oil leak, just a few drips which I have been monitoring for a few weeks now which seems to be coming from the back of the engine, between the dipstick and the distributor, it really is very small, but still, I don't want it to become a big problem.

 

All help, tips and suggestions very welcome

 

thanks in advance.

Take the terminal off the sensor and short it to earth. If the gauge goes all the way to the top then the wiring is fine so the sensor must be faulty. If the gauge doesn't move then it's a gauge or wiring fault.

or someone has stuck the wrong wire on the sender.

Oil leak is probably the o ring between the cam shaft and the distributor needs changing (just doing mine) or the cam shaft cover

Thanks Phil looks like I have a few jobs to do!

 

just as well I can't get the car out of the garage for 3 weeks due to scaffolding round the house!

stroke of luck as the gauge has started working again, so going to leave it alone after all.
