The car performs a vacuum check at start up. If there is a leak in the tank, lines etc. the fuel cap will come on.

I'm not a mechanic but from experience I suggest that before you start with repairs, start with the fuel. You may have either picked up some dirty gas when last filled up or just stirred something up in the tank. Try a fuel cleaner from any auto parts store. Also, and this is probably not realated, the check engine light may come on if your gas cap is not tight. Good Luck

Did you change the in line fuel filter? It may have sediment in it that will settle out and allow some fuel to flow. As the fuel flows the sediment travels to the outlet part of the filter blocking fuel flow.

My cadillac catera is making a loud clicking noise in the motor and the fuel caplight turns on please help me


First, make sure the cap is on tight at the fuel tank.

Then, investigate the loud clicking noise in the engine.
Check engine oil level and add as necessary.

If this doesn't solve the problem repost your problem.

No fuel getting to where it needs to be.


Check that the fuel pump is working. Take th egas cap off and have some-one turn on the ignition to run. If you hear a light motor sound it should be OK.
If not, you need to make sure you are using the right key for the car. The key is coded and if it is not the correct key, the engine will crank but the fule will be cut off via the pump.

Check the fuses (under the steering column behind panel) for a fuel pump circuit. I beleive there is fuel pump relay which needs to be checked.

My 2000 cadillac catera check engine light is on and the tc light is on and it idle's low


What have you done so far. I would start with looking at the cars repair/maintenance history. Have the codes read (might be helpful). Could be anything, depending in what direction you need to go you might want to check for cyl. miss-fires, bad coil, IAC, fuel pressure, clogged CAT. CMP sensor. Let me know if I can help anymore.
