My 03 Saturn vue 3.0 engine died fuel gauge and temperature all stop working. Main engine relay and fuel pump relay not function, please help.

check connections wiring and for proper install and no fuse

If it is a new starter and it is not turning over the engine it has to be because it is not receiving power. Check battery connections and start solenoid and any fuses/relays in the mix.

need more information any check engine light //does it restart intermediately-- no start --no crank --overheating ---check key if loose in ignition can cause shut off ignition switch can be worn or damaged --fuel pump -fuel relay going bad --overheating --egr valve carbonning up---tune up -these are the usual's

Possible that the ECT (engine coolant temperature sensor) is faulty, or the wiring to it has been compromised. Try looking the wiring over. If nothing jumps out at you, replace the sensor. Keep in mind, it's the season for critters to seek warmth from engine heat.

Well son, there are MANY reasons that might cause "fluttering" in your gauge. Mine started doing that, then I started getting a warning LIGHT for overheating. My solution for that was a fault in my fan. There are 2 speeds on my VUE'S electric fan. The one that required attention was speed/high (the speed/low was working). If your getting an intermittent short, watch both the temperature and fuel gauges to make sure it's not a real (both will do the "fluttering at the same time if it's faulty short) overheating problem. If you have an OCD-2 reader, plug it in under the driver's dashboard and go to function "live" read the engine temperature. If that's normal it will be between 120F-200F.
Faults may be relays in the under-hood fuse panel (there either good or bad, you can't see anything like other fuses) and there are the 30 amp or 10 amp fuses inside the same fuse block for that electric fan.. I've found that if I open the hood and start your car, after it warms up, there are tree things that could happen.
1: the low fan starts up, then start your A/C, the high fan speed comes on (normal, check your temp gauge).
2: After you warm it up, the low speed fan starts up, but with the A/C on, the high speed fan isn't coming on (bad high speed fuse or relay).
3: after warm up, the low speed fan doesn't come on, but starting the A/C the low speed fan comes on (bad sensor I think).

I've had a ghost in my VUE since I bought it, gone through 3 computers, CVT sensors, key won't turn without destroying the key. One time, I used the horn to get some deer off the road and the damned thing wouldn't shut off. While I was under the hood trying to get it to turn off, TWO cops stopped, they shined their flashlights on the fuse block and one on the diagram for me to pull the right fuse. I took it out, plugged it back in and it worked again! The shop didn't find a thing wrong with it, but the thing works still.s

first of all, check the fuel pump relay to see if it is going bad. if it is ok! also try this, Have a person turn key to on,, and put your hand on bottom of fuel tank. if the pump is turning on, you will feel a vibration in tank. you may have to do this a few times. the pump only turns on for a few seconds to pressurize system, or to get fuel to the engine. just keep turning key on and off to recycle fuel pump. Good-Day! Hope this helps! relay for pump may be bad.< Check this first.

How is it "tripping" ?
The pump gets a signal from the ECM as long as the ECM knows the engine is running.
Is the check engine light on ?

The plug at the back of the panel has come lose.Remove the dash panel and push plug on firmly.Hope that was helpfull.

can you tell me why does the gas thing does not go up when i fill up

Sounds like the fuel pump may be going out. By the way the power steering is electric in Saturn, so it does not require the engine to be running.
