There can be one problem among several parts on your car and it involves getting the starting signal to your starter.

Working backwards from the starter there is a starter Solenoid and on some GM products it comes with the new starter. On other setups there is a separate box solenoid which has a main cable from the battery going into it and coming out of it going to the starter.

Either setup has a one or two trigger wires that are small guage. These carry the starter signal from the Safety Interlock and Ignition switch. The Safety Interlock can be connected with a foot on the Brake pedal or clutch pedal depending on the trans,

When the Safety interlock connects, it allows the signal from the Ignition switch(Start position) to reach the starter solenoid and engage the starter.

You could have a bad Ignition switch, Safety Interlock, or starter solenoid. It can be a matter of adjustment of worn parts. You have purchased the expensive parts already.

Its a toss up over which to do first. Vehicles all seem to break at the worst time. If you have time to test the power going to the starter solenoid, the trigger wire, then you can eliminate or confirm a bad solenoid. Then you are faced with why you have a dead trigger wire.

It may only be an adjustment problem or the Ignition switch or Interlock.

I hope my solution helps, please rate my info.

I have had the exact same problem. There is an ignition lock that probably went off. There is a fuse box under the hood. The fuse that says ignition on it pull it out and put it back in. This should reset the ignition lock. Its a safety feature because the car thinks that someone was trying to tamper with it.

first remove the battery and take it to a auto parts place and have them check it. move on from there. if the battery is good the do a starter draw test. take a meter and hook it to your battery. now have someone try and start the car. if the voltage on the battery drops from 12.8 to below 9 volts then the starter is bad. if the voltage doesnt drop much at all then its prolly the solenoid both of which require starter replacement since most solenoids are on starters. if still nothing then check ignition switch. but before anything else ensure vehicle is in park. if it is in part use a meter to test neutral safety switch.

Starter solenoid , or wire that leads to it.

Also , if standard transmission , may be the switch on clutch pedal is intermitant.

Engine won't turn over unless it thinks you have your foot on the clutch.

It should be located on the outside of the frame rail,forward of the right front tire. It should look like a ceramic type ballist with a pigtail and one bolt holding it on. If the pigtail has a connector dont forget to check for water, rust, etc. also check for wire damage. It should be the culprit though since by jumping the relay you are in theroy bypassing the resistor. I hope this is correct I didnt have time to pull a diagram and look at it but I am pretty sure this is correct. Thank you for your vote and comment. I hope this helps, good luck my friend.

Used parts such as starters and altinators don't last. It might **** but it sounds like you need to buy a new starter,altinator, and battery. Or just start with buying one at a time.

it's sound like you have a electrical problem between your ignition and the auto start. To get the key out underneath the sterring column there is a little square tab that you can pull off. after you remove it you can push a button in that hole and it will release your key.
