car wont shut off

Ok I notice a number 10 fuse missing from the fuse box I believe its mark gage so I put a number 10 fuse and started the car just to see if it made a diffrents. Went to shut the car off turning the ignition key to the off position but the engine contiune to run I reach back under the dash to the fuse box to remove the fuse and the car shut off went to start the car one more time the engine turn over but I needed to give it gas placing my feet on gas paddle just to keep the engine running engine sound and feel weak lacks power.
I place the fuse back in and start the car once it started I quickly remove the fuse and the engine shut off. Went to start the car again and she start up with no problems and has power again. I question is do I leave it alone or see why the fuse is missing and get it fix?

I've heard that "dieseling" can be caused by bad fuel

Re: car wont shut off

Sounds like you have hacked up wiring. Best bet is to get yourself a multimeter and a Haynes manual and start checking thru your harness, one circuit at a time. Begin with the Gauges fuse circuit, and then the ignition circuit after that, tracing each wire to check for physical problems (worn/melted insulation, exposed conductors, etc), and do continuity checks to a known chassis ground. Typically, orange wires will be "Hot At All Times", pink is "Hot In Run and Start", anything else is dependent on the circuit with the exception of black which is most commonly ground. If an orange or pink wire has low resistance to chassis ground, then check that wire for problems. If the wires check out both physically and pass resistance checks, then you need to branch out and start checking the rest of your circuits. You can also check both sides of the fuse with the ignition on and the fuse removed to see if you are getting voltage on both sides of the circuit. With the fuse removed, only the feed side of the fuse location should read 12V. If both sides do, you have a cross wired circuit somewhere.

Thanks I will try testing the circuit using a mulitmeter this weekend.
