Re: lost power to my ignition where should i look
Trace the wire back to its key on ignition source. Most people will run a wire off of the fuse box. Don't get in a hurry, look carefully and find the source. I do not recommend the original ignition source, because that wire is a resistance wire. Meaning that there is a built in voltage drop to about 9.5 volts. You need 12v+ to operate the HEI properly. Make sure also that you have 12v+ when cranking the truck.
