chevy truck help needed

1994 chevy 4x4 1/2 ton truck. 6 cylinder 5 speed. truck will not start, will not engage starter, will not turn over, no clicking no nothing.
any ideas ??
I can jump across the solonoid but it will only run the starter it will not engage it. thats the only way I can get the starter to turn.

 

Did you try wiggling the shifter around while the key is turned in the START position ?
You could have a bad Neutral Safety switch or a bad clutch switch.

 

I have tried different positions and with clutch it. I didnt need to push in the clutch before so someone might have by passed the switch. do you know where its located?

 

On most vehicles I've seen the safety switch is on or near the top of the clutch pedal. Does your key have a chip on it? The reason I ask is I've spent all day today working on a LeSabre only to fid it was the chip on the key.

 

Get a friend to hold the key in the start position and give the starter a few good whacks with a bar or a wrench.

 

no chip in key, I am looking for the switch tonight,
I also have already replaced the starter.

 

So your starter is new
Is the solenoid new as well?

You cant get it to engage when crossing the solenoid? It should. Make sure it is out of gear when doing this.

I would pull the starter off and bench test it with a pair of booster cables and find out why the starter drive is not coming out.
If it is coming out, then look at the flywheel ring gear for missing teeth.

Coming back to why the starter wont work, when you cross the solenoid, do you do it from the ignition wire (purple I think??) to the large battery positive or just "JUMP" the solenoid from large battery wire to the large armature bar going into the starter??

 

truck is running, what it was, someone had bypassed the ignition safety switch on the clutch, they cross the plug with a wire, the wire fell off.
thanks for all the help.

 

the solonoid is bad

 

If the starter works when jumped, the problem has to be in the igntion itself.
Or if it has one of those anti theft cards next to the brake release. check to make sure it is in the slot if not use a razor blade it is the perfect size

 

thanks again it was the clutch safety switch. it was bypassed and the wire it was bypassed with came out.
