Ive had an autometer electric oil gauge for about 2 years now mounted in the block. For whatever reason, it was reading at idle fine, then whenever I reved the engine or started to move it would loose signal. Now when I start the car it no longer works. Do the senders just go bad? Is there anyway to test it? Ive read online that grounding the sender helps, but Ive never had to ground it before, why the change? I really dont want to have to replace the sender, its a pain to get to, but if I have to are the replacment senders cheap? I've read that they should be remotely mounted, but ive seen lots of peoples setups that are similar to mine. Would the vibration really make it just stop working one day?

Any insight would be extermly helpfull as I do not like driving around with no oil psi gauge.

Thank you.

Yes, senders can just go bad. I don't know if that's the problem or not. Make sure all the wiring's up to par, and the gauge is functioning correctly before you change it though.

you can buy the sending units from summit too.

Oh sweet thanks. To bad the replacment is almost as much as I paided for the gauge. If I cant get the sender to work in the car now, I will just buy a machanical gauge with braided line.

VERY common item to go bad, most the time customers complain of an oil leak and thats the source of it. This sensor(switch) was used on many 1996+ DCx vehicles...

Uh, he's talking about a sender for an aftermarket oil pressure gauge. Not the oil pressure switch for the idiot light.

Sorry my bad

thats why i used a mech oil press gauge cause i heard the senders don't last long

Yeah but we don't want hot oil in out passenger compartment.

Why not? Nothing wrong with a PROPERLY INSTALLED mechanical gauge.

Worse case senario, what come to mind is if you're in an accident and someone plows into your drivers around the a-pillar area to possibly rupture the line. If the motor continues to run then yeah, I don't think you'd want hot oil possibly spraying everywhere

I don't know if it's this particular forum or what, but why are people so scared of a mechanical oil pressure gauge? Install it right, don't kink the nylon line at all, don't run it near anything sharp, and only make it as long as you need, and there will be no problems. They've done this for decades now!

Agreed, when it comes to mechaincal gauges this is one of the 2 I recomend, fuel is a different story.....
Ive had numerous cars with the mechaincal oil pressure gauge and all is well...

Thanks guys. I know a mechanical gauge can be dangerous but I planned on using braided line. Ive always hated short sweep gauges and Ive never liked how inaccurate electric gauges are. If I am going to go though the trouble of switching out the senders, I might as well go to a mechanical gauge.
