Crazy oil pressure

[JoRoW99]

I've been having a strange problem with my gp for about a month now (I probably ignored it too long). At start up, my electric oil pressure gauge will do the normal sweep, and then peg at 0. Doesn't change if I rev it. After it gets warmed up the pressure will sometimes be 70 which is what it usually is or somewhere around 40. It will also randomly peg 0 or 100 while driving. I have a video of it staying around 40 cruising, then jumping to 70, and switching between those two , then going to like 3 psi, all while cruising. And sometimes if its at like 30 and I rev it to try to go up it just pegs 0 again. What is going on?

Either a short to ground or its losing power.

Or the oil pressure sendor itself is on the fritz.

id say short somewhere

Ok that's what I was hoping, it's not wired very well. I'll have to redo it and see what happens. Would my motor have blown by now with real oil pressure like that?

 

[MoarkatsINmuhtrailer]

yeah lol 3 psi...


you would hear the rave going on in your oil pan

 

[JoRoW99]

Could there be a clog or something near the sensor? Because the needle still kinda wiggles like its on when it's at 3psi

 

[MoarkatsINmuhtrailer]

i doubt it.

I'm betting you have a bad ground.

 

[JoRoW99]

Wat u no about oil pressure guy u dun even haz headers

 

[GTPpower]

Throw some headers on. That'll fix everything.

Problem exists between steering wheel and seat. Fix the known issue before you try to diagnose the known issue as another issue, like a clog etc.

 

[JoRoW99]

Yea I started fixing it, I correctly spliced and soldered the gauge power wire into a pink ignition wire instead of the DRL power wire. It looks to be grounded well, the same place as another stock wire, but I'm going to move it and see if has any effect. If that doesn't work I'll hook up the stock dummy light to see if it is really reading less than 5psi.

 

[BillBoost37]

If it reads less than 5psi..you'll hear the noise sooner than you'll read the pressure.

 

[GTPpower]

And, if that happens, you better sell me the car for cheeeeeaaaaaaapppppp!

 

[JoRoW99]

Nah you wouldn't like it, it has headers. You should be the one selling me an l67 for cheeeeeap.

Ok so uhh I googled autometer oil pressure sender and that is not what I have installed...it looks like an autometer fuel pressure sender.

ahahahahaha
