Jeep won't start, no click - nothing

I just replaced the power steering pump yesterday and drove for at least an hour on my jeep back to my house - so that should have nothing to do with this, but I figured I would mention it.

When I try to start my Jeep, nothing happens. No click or anything.

What I've done so far:

I checked the battery voltage and it read 12.5 volts

All my lights work and are not dim

My lights do not dim when I try to start it

I can hear my fuel pump

I checked the starter relay using an ohm meter and it read around 65 ohms on two tabs and 0 on the other two tabs, so it's good -- I also just tried using a new relay and it didn't fix the problem either

I then put the dmm in the starter relay slot in my fuse box and got a 12 volt reading from pin number 30

I did the same thing as above but put my key to the on position and got a 12 volt reading from pin number 30, 85, and 87

I just tried putting a fuse (20amp) in the #20 slot behind my glove box (which should bypass the clutch safety switch, i believe) and that didn't work either.

I took my steering column panel off and turned my key to the on position and then removed the key's lock cylinder and tried to start it with a screwdriver and that didn't work either.

I tried hitting my starter and solenoid with a screw driver - no luck

On my starter there appears to be 3 bolts. I attached a jumper cable from the top left one to the positive battery terminal and nothing happend. I then attached the jumper cable to the bottom left one to the positive battery terminal and all I saw was some sparks but not very much. I did not connect it to the far right one because it looks like a ground, but I can see the red positive wire going to one of two (or both) of the studs on the left. I can't tell which one because of the black plastic cover it has on it.

Here is a picture of my starter so you can tell what I mean by 3 studs. (In the pic you can only see one of the left, there are two - vertically)




Anyone have any other ideas? I've literally tried everything that I have found on-line. If you want pictures, I will gladly post some. I'm completely stumped on this. It ran perfect yesterday.

Not sure how/what you did exactly with the ignition cylinder, but I had a similar issue with my Jeep awhile ago and the cylinder internals had broken and thus would not let the Jeep start. Perhaps there is a mechanic near you that you could take your ignition cylinder to and have it inspected?

But I took that whole cylinder(The one the key goes into) out of my Jeep and used a screwdriver instead to start it, and it still didn't work. So that couldn't be the problem

Well, like I said above I'm not sure what you did with the screwdriver exactly or where in the steering column since I wasn't there, so I can't say for sure that a screwdriver would even work. Have you successfully started a car this way before?

If you take that cylinder out, then there is a little hole in the very back that a screwdriver can slide into, you then turn the screwdriver like you would your keys. It's like what you see in the movies sometimes - just no wires involved

Interesting...I figured there was some way since we don't have PATS keys but I never knew for sure

Do you have an assistant to help turn the key while you check something?

I do not, he just passed out. I have tried hitting the starter though.

I will have one tomorrow though, what's your idea?

So obviously the big wire from the battery goes to the starter. Its under that black cover, it needs 12.6 volts or there abouts. There should be a small wire on the solenoid, when you turn the key the small wire will indicate 12 volts, would be easy to see with a test light.

so if the small wire indicates it is getting power, that is the signal that energizes the solenoid. Tells you the ignition switch is working .

I could leave my key in the on position, and check that small wire with a dmm?

you could jump the big red wire to little starter signal wire and that will also energize the solenoid and the starter should spin.

small wire only gets power when the key is turned.
