    I have a 1989 Isuzu pickup. The key has become almost impossible to turn. How do I remove the cylinder & replace it?

    Thanks for the answer. I was able to change it out after pulling the steering wheel. It was pretty easy after that. Two screws that hold the turn signal lever, pulled it back, one brass button, it all came out.

Lock cylinder & keys is about $90. Switch alone is around $45 with wiring harness. Don't know if switch comes with a new lock cylinder. Thought I had to replace mine, so read up on it in Haynes Repair manual before jumping in. Just did this today. Took my switch apart, cleaned it - nothing wrong, put it back together. Doing that, I didn't have to remove the lock cylinder, so I can't offer hands on with that.
My '89 pickup does not have shearhead bolts as described in the manual - guess some models do. Here's what the book says (with my add-ons):

- Disconnect neg. battery cable
- Remove steering column cover (bottom half - 5 phillips screws)
- Unplug ignition switch wiring harness (I didn't do this - must be back up under the dash somewhere)
- Remove the two ignition switch/steering lock mounting bolts (phillips) If shearhead bolts, cut a slot in the head with a chisel, then use a flat blade screwdriver to remove. You can get to these two screws by turning the steering wheel first one way, then the other. (Once you get in there, you'll see removing it is not a big issue)
- Remove switch assembly from steering column.
- Install is reverse of removal procedure

Ran out of gas, prime the fuel injectors

No priming needed

When you turn the key on, if
the fuel pump comes on, you get fuel

Any air goes into the cylinders

You probably ruined the pump running
out of fuel or it is just old & worn out

The ignition cylinder turns free not engaging the starter. I need to know just what is between the cylinder and the ignition switch

The cylinder engages a gear which moves a rack (straight piece with gear teeth) which changes the rotational movement into straight movement. The rack connects to a rod which runs down the top side of the steering column to the switch which is above your feet. Most likely, the switch is bad which is fairly easy to change. The second choice is problems with the gear/rack assembly which is very difficult to get to, requiring removal of the steering wheel and a lot of little pieces. Good luck.

1989 Isuzu I-Mark won't crank over.

The winding noise sounds like it may be that the engine has lost compression. A compression test on all cylinders will determine this. The pressure should be approximately 100 lbs +/- 10% in all cylinders.
