No power from ignition to starter.

78' 510, automatic. She stopped for coffee and went to start the car again and got no response. Lights still work, all fuses look good. starter has been tested. help...

Make sure it firmly in PARK or try NEUTRAL.

 

(if not)

Place in park with key ON. Use a lug wrench  to short across the starter bolt with the battery cable on it... to the small terminal with the Black/White stripe wire on it. Motor should crank over and start to get you home. Probably the above.

car is home, starter jumps fine and was getting pushed out when tested at shop. Radio wipers and fan don't seem to be getting power either.

 

Her ignition swicth works in my car, mine has no effect on hers

Today I just quite possibly figured out that my starting issue was nothing more than a bad connection, I have been having issues with starting my 720 diesel, I hit the key and nothing happens except clicking, then eventually it won't even click.

But when I use a big screwdriver to jump the starter between the main cable from the battery to the starter/start activator post on the starter solenoid, it starts right away, but today I did something different, I used a remote trigger to see what would happen, well what happened was a lot of smoke from the posts before the starter decided it wanted to work, that was when I realized, that even though the nuts were fairly tight holding the cables on the starter, they still were not making a good connection, so I tightened them even tighter, and now the key works properly again.

I was going to say weak start signal. My sedan was about 6 volts and the solenoid would always click twice and crank (usually) on the third try.

Fuses are good...but no power to the fuse box, i can follow the power from the batt until it goes into the harness, cant find any power inside the car.

[datzenmike]

Power to the fuse box is either directly for the battery or switched through the ignition. Stuff like heater, radio, wipers are through the ignition. Interior lamp, brake and headlights, clock are not.

no power with ignition on.

[datzenmike]

Then either the ignition switch is bad or the connection to the harness or the harness to the fuse box. You say you've swapped ign, switches and the fuses are good.....

 

NEVER trust a fuse by looks. Get a quarter and short across the two fuse clips to go around it. If the fan comes on the fuse is no good.

FIXED!!, apparently there were 2 fuseable links from the batt that werent plugged in. They werent plugged in when i took stuff apart so i'm very confused why they were disconnected.
