I just bought an 02 mean streak vn1500 and the gauges aren't working!..... Any ideas?

Just because it pumps gas doesn't mean it is at the exact pressure it should be? Most fuel pumps have a psi of 40 to 45 psi, your fuel pump could be pumping at 25 psi or less which is not enough to start your car even though you can see some fuel pumping out. A simple tool to check fuel pressure can be bought at any auto parts store, check the specs on the fuel pump for your 02 Chevy first to see at what pressure it works, then use the fuel pressure gauge to check it. Anything less than what the specs on your fuel pump are suppose to be and you have a bad fuel pump?

Let's say your fuel pump works at 43psi, you hook up the fuel pressure gauge and you find that it reads 25 to 30 psi, that means it's not enough fuel pressure to start your engine.

Its mixn w the coolant..probly need a bottomend rebuild cause berings will b toast. Seek a privateshop

You more than likely have a bad fuel level sender. It’s attached to the pump in the tank

TO ALL VN1500 OWNERS....This once happen to me,
I went to the garage to start the bike "Nothing ""The first thing is the lights are bright but no turning over,Next you think the solenoid is kaput but the answer was very simple and the fix takes 30 seconds..
Do not take the bike to bits looking for other problems and look at the clutch leaver and you will see some wires going into a plastic shroud going into the switch in the clutch leaver, Make sure this has not popped out if its connection as it some times may do after a few years due to constant turning on the handlebars,
When this is not connected you will have a bike that will not fire up but comes alive and you will hear a clicking noise but this is from the engine carb area and every function of the bike will work but it will not turn over, Worth looking at and saves sixteen quid for a starter unit you never needed.

check the side stand safety switch its probably stuck

If you have a multimeter check the voltage across the starter when you press the starter button. If not try it with a 12v bulb this will tell you if you are getting any power.Try these then come back.
