...the fuel guage is sticking and sometimes moving around to different levels......any idea what the problem could be? any help on troubleshooting would be great too....thanks!

 

What car do you have? It could be 3 things, the gauge itself, the wiring or the sending unit (float)..

 

87 crx.....i posted the topic in the crx forum but i recieved no reply.....tell me this....what type of voltage is going into the gauge cluster for the fuel guage.....will the voltage increase as i fill up the tank? this will help me troubleshoot the problem...

 

Damn I don't have the manual for the 87 CRX so it may be different. Try seeing if http://www.hondahookup.com has that service manual. On a EG chassis you would remove the access panel by the fuel pump. There is two connectors, one for the fuel pump and one for the gauge sending unit. Disconnect the fuel gauge sending unit connector and turn the ignition switch on. Use a multimeter to check for voltage between the terminals of this clip. (YEL/WHT and BLK/WHT in the EG, most likely different in your car.)There should be between 5-8 volts back here. If you don't get any voltage check the wiring. If you got voltage, turn IG off, jump the terminals you got voltage between with a wire and turn the IG on again. The fuel guage should move towrds the F mark, if it doesn't relace the gauge. Make sure to turn the IG switch off before it reaches the full mark to avoid damaging the gauge. If the gauge moved then the sending unit is bad. Again this is for the 92-95 civic so the CRX may be different..
