Hi. I know this may sound sketchy but I have no money to spend and I need a solution.
No start. Lights, ignition buzz, radio, all electric works, battery new, new ground cable, new alternater. 48k original miles on car. At random times, No nothing when turn key. Silence. No head lights dimming. This happens randomly but most often in the morning or night. Usually starts right up in day. And for weeks (even years) at a time great. Then out of nowhere - no nothing. Then 15 mins, or and hour, or later in the day - starts right up. I think it is ignition switch, but maybe starter or cilinoid? This was happening more frequently. Now didnt start for 3 days, then today started once, now wont start.
i need a solution - now. I have wrok at 6am Weds and I cant not know if it is going to start. I want to by-pass the ingition and I do not know the wiring scheme. I am novice-intermediate skill level.

To check if it is the ignition switch, check for battery voltage at the Yellow wire when ignition switch is turned to START.

Well thank you. I suppose these wires are the wires that lead up and then out of the steering colum? And then how do I use them to start my car?

OK Im calmer now.
OK. I am not a mechanic and have limited resouces (money, tools). So I can turn my ignition to start, that is power on, and cross the brown-in to the red-out? Is this correct? Is that not the same as arcing the starter poles? Im just by-passing the ignition by crossing those wires, right?

The red is power source and Bown is for engaging the starter solenoid.

That is similar to arcing the starter solemoids.

Ahh yes thats what I figured. So I just went down and my car started right up. What do you think the problem is? The issue is that in the day it will usually start. But in the morning it wont - like when I have to get to work. Im afraid to drive today because I may get somewhere and then it wont start. Advice?

Under the sterring colum there is a wad of wires goin into it. They are separated 6-4. The brown is in the 6-set, with (I forgot to bring up what I wrote) white, purple, and others. The red is in the 4 set. They are separated by white plastic clip insert. A 10- set separated 6-4. Would I strip a section of the red and clip the brown and touch the brown to the red? Or vice versa? Or is there a better way. I found the coil behind the block, but where a relay? Would this method work as well?

Or maybe I could disconnect the battery and just splice those red and brown wires with extension wires ( T splice) so if the car doesnt start I could simpy use those? Would that work. Please inforn me, I dont want to screw things up more than they are. I appreciate your patience with my novice-ness.

The red is the power source and when ignition switch is turned to START, there should be battery voltage at the Yellow wire.

The Brown under the steering column is not for the starter and you cannot use it to crank the starter. Starter relay is in Power Distribution Center, underhood. You can try using the Red and Yellow to crank.

When it cannot start, you need to check if there is voltage from the yellow wire. If no voltage is present, the ignition switch is faulty.

I would suggest checking the starter relay. Try swapping out with another relay to test.

Lance did you solve the problem? I know the post is over 7 years old. But I to am having the exact same problems. And there does not seem to be an answer here. Lance if you are out there did you solve the problem?

You should post a new question, and PLEASE list the engine size, along with the mileage and transmission type. This was a conversation between two people and shows up on our list as already having received a reply. None of the other experts are going to see your addition or have a chance to reply. That won't get you the help you need?

What are your exact symptoms and observations, and is this an intermittent problem? Do you hear the starter relay click once each time you turn the ignition switch to "crank"? This is an extremely simple circuit, but the symptoms will dictate the likely cause of the problem.

Try cranking the engine after shifting to neutral.
