pyro gauge

[dentexpowerstroke]

Got a call from my fiance asking what the red light on my pyro meant (it's the warning light) she said the gauge would be at 600 then jump straight to around 1500 the right back down. Does this sound like the gauge or sensor could be messee up or something I should look into?

I think I'd check where the probe goes into the manifold to make sure it's tight. Then I think I'd check the back of the gauge to see the connections are tight also. If there's a ground wire, check that too.

That was my plan. I just didnt know if there was something internally i should be worried about.

I guess it could be the gauge itself. Usually, they are pretty reliable.

I meant internally in the motor like an injector hanging or anything like that.

Not if its happening that quickly.

It's a digital gauge she said it is about 500 then will jump to 1500+ and bounce around numbers there for a second. Sound like its just a bad connection still? I'm at work so I cant see exactly whats going on just wanting input incase I need to tell her to pull over.

Sounds like a loose of pinched wire connection. That happened to me before. I had the wire pinched coming into the cab and it pulled on the connection at the back of the gauge and caused the same thing you are describing. Check your connections then make sure the wire is pulled super tight.
