there is something serriously wrong with my gauge cluster speedo rarley works and even gets stuck sometimes rpm works most of the time but goes up and down alot oil presure goes off sometimes but comes back on and abs e-brake and seatbelt lights are on at all times and wait to start and check engine come on usualy come on when rpms are freakin out and also my lights flicker when things go crazy but the truck dives perfect abs and e-brake fuction perfectly. here is what i think the problems may be the batteries are 2005s but they start the truck fine even in the cold and when its been siting, posibly a bad ground, and the vss, maybe the gauge cluster itself tell me what you guys think

 

I've heard of problems like this when the crank sensor starts going bad.

 

do all our 98's have voltage regulators? my fuel gauge is a liar it goes up and down and never stays still. my speedo dont climb till 20 mph thats all mine does

 

Voltage regular=yes Whatever fp gauge you put on a 12v will jump. Just because the lift pump is ran off of the cam so it will not get a good reading. What you need to do is get snubber and a isolater for it, to help calm down the gauge because where its moving all the time itll kill the gauge evently

 

well im swappin clusters so the problem will remain till i get those two things?

 

Voltage regulator is in the PCM unfortunately.

 

dang dodges

 

I doubt it has anything to do with the batteries or the volage regulator. But, as for the voltage regulator in the PCM, it's bypassible.

well i just hate it when i fill up and my gauge jumps up and down and wont stay in one place then after i turn the truck off it will quit actin up when i start it until i stop a redlight

 

did you check the ground to the body one time my gauges went all crazy like that and the ground from the body to the battey broke.
