Got a remote starter put in and now my temp gauge won,t work..........

are your brake lights functioning properly? remote starts sometimes use this as a fail safe, or a bent hood pin switch? Also It may need the tach reprogrammed if used. there may be a seperate fuse for the starter.
here is the link to the installation manual: http://www.directeddealers.com/manuals/ig/viper/n4102v_2008_09_web.pdf
and the page regarding this issue: • The remote start will activate, but the starter never engages.
1. Check for voltage on the purple starter wire two seconds after the remote
start becomes active. If there is voltage present, skip to Step 4. If there is
not voltage present, advance to Step 2.
2. Check the 30A fuses.
3. If the gray/black wait-to-start wire is detecting ground upon activation, the
starter will not crank.
4. Make sure the purple starter wire is connected on the starter side of the
optional starter kill/anti-grind relay.
5. Does the vehicle have an immobilizer? Some immobilizer systems will not
allow the vehicle to crank if active.
6. Check connections. The heavy gauge remote start input wires on the
heavy gauge 10-pin connector should have a solid connection. "T-taps"
or "scotch locks" are not recommended for any high current heavy gauge
wiring.
good luck.

With a voltage meter see how many volts are at the starter terminal. If not 12+ volts you have a bad connection. Check connection at the starter solenoid. Does it have 12+volts? Short the solenoid. Does it put voltage to the starter?

You can't.. Best to get the temp gauge working before you drive it as an engine will overheat within 10 minutes if you have a fault

when you state it wouldn't crank, do you mean the starter won't engage or that it just spins over and doesn't start? if no gauges or no starter engagement, then check the battery, battery connections,and the starter for excessive amperage draw. if the starter spins and the engine won't start, then check crankshaft position sensor first. the crank sensor is a more common failure than the distributor or any of the other things you mentioned.

Sounds like it could be an instrument cluster fuse or a possible ground issue. fuse would be easier. Did you have anything added recently such as a stereo or remote car start system?

more then likely its a bad starter. or the cable to starter.

Hi!

I think you will need to program the computer soon as you put new cluster in. Good luck

If you put the can freon in you probably did not equal out the high side as well. The gauge on the can freon won't help you. You need the professional gauges to get it right. Sounds weird but That's what happens on GM's when the pressure is not correct for the ambient temp.

sounds like a dead battery, and it sounds like the van has a starter kill relay hooked up the the starter solinoid wire under the dash

when you remove your oil cap is there foamy **** on the inside of the cap, if so you may have a crack in one of your gasket
