Car wont start without it being jumped.....tachometer...radio, nothing works

bad tachometer or sensor, nothing to be concerned about if you don't mind the pack not working

You got a jump and it ran fine? It's your battery. The lights and radio are much easier for a battery to handle than spinning a car engine. Again, if all you needed was a jump, you have a bad battery.

have you checked the fuses? it more than likely blew a fuse if not then maybe fried wiring from jump start.

OLder cars YEs you can jump it without a battery. But in newer cars that use computers and advanced Eltronic ignition/timing/ful injection you have to have power to the cars computer. without a good battery the car will not run.---------------------------------------------------------------------------------

Hi Chris, Check the battery and terminals. Try a jump start and if that works replace the battery. Regards John

The first thing you need done is to have the battery load tested and verified as being in good condition,.

When you try and start your truck without a jump, what are the battery voltage shown on the gauge, there are times when the battery are just in too bad of a shape that even a jump wont help. Without the jumper cables monitor voltage indicator, it should not fall below 10 volts.

Good luck

Clean the battery cables on both sides,under bolts and replace bolts.
