My rain guage quit working .reads 0 all the time. it is the accurite 5n1

Pressure will drop to zero if it doesn't fire up and stay running. This is to prevent to pump feeding a fire in an accident when engine quits.

you have a short in gauges or a bad computer

Well, first off would be to replace the faulty sending unit so that the oil pressure will stabilize. Second, if I'm reading this correctly that you have no oil in the oil filter at all? If not, your oil pump could be quitting or it did quit. It's recommended not to start the truck until it can be checked for oil pump operation. Have the valves been chattering badly? The only 3 things that would prevent oil from getting to the oil filter are a blocked passage, a failed oil pump or no oil in the motor at all. When the oil guage has that fluctuation is when the pump is going out or again the engine has no oil or a leak so massive that the guage can't hold a stable reading. Good luck

3 problems and no engine stated.
oldest story ever on gas engines.
1: for the transmission question, check levels and scan it yet?
2; in the rain. questions, ever get tuneup this decade
no engine stated.
if the crank sensor, has 1 bolt do not play with it ask how to do it and not wreck the new one. ok? as seen on 4.0L engines.
fuel gauge can be bad fuel gauge sender.
stalls 101: (1 top cause of 50)
if you scan it ,at the stalls it will tell you why it stalled. most times.
ever try new spark plugs.>?(and filters)

4.0L or 4.7L engine? gas. which one.
4.0 has a spark coil RAIL, making owners fear spark plug changes.
(bad to the bone that) and the coil pack can be just dirty
and when it rains it conducts HV electrons and shorts. until dryer.
same here but different.
the 4.7L has 8 coil packs, COPS, any can fail, boots fail
and sure bad spark plugs, no spark plug made last the life of an engine, so is called a TUNEUP part.
or SCHEDULED SERVICE POINTS (prevention)

if 4Liter engine the inline 6

this red spacer must be used on all news CKP sensors
or the next startup wrecks the new sensor
seen on this forum 1000s times, and now car as dead spark
sad to watch.
the paper and glue spacer is 0.030" think, 30 thou !
(took lost of work to learn how think, got it from maker)
most schlock stores sell it lacking this key #6 part.... adding to the pain.

In order to read your obd code you have to turn the key on and off three times then the fourth time leave it on and watch the check engine light for flashing the code. There is delay before it starts to flash. Then it will flash and pause before it goes to the next number. for example one flash is 1, two flashes is 2, and so on till it flashes 5,5, which is the end of the code. there is a pause between numbers. You will have to try it a few times till you get a feel for it.

Hi Norton,

What has happened is your speedometer and tachometer drive motors are failing inside your silverado instrument cluster. I see this very often in GM trucks, to fix the problem you need to have your instrument cluster rebuilt.

Check out this article that talks more about it http://drspeedometer.com/chevy-silverado-instrument-clusters-why-they-quite-working

Thanks,
Fred

check your speed sensor on your transmission

check the cable which leads from the tranny to the dash, most of the time the cable or sensor went bad

You need to take your vehicle in and get a calibration done on it. Hope this helps

I have a chevy cav 03 and my problem is just in the gas guage and temp guage now i cant seem to figure out how to fix it but for a quick fix i have jut been pulling out the instrument panel fuse and putting it back in it seems to fix t
