Having problems with your 1989 Chevrolet K1500 ?

So my truck is an 1989 Chevy scottsdale, C/K1500. It will not turn over, when I turn the key forward nothing as if I didn't push the clutch. Lights all come on when the key is turned forward, everything works just will not start from the stopped position. Now when I jump the clutch and push start it, it starts. Just replaced the starter, brand new. Everything was hooked up the same way it was unhooked. There is no clicking no noise other than the fuel pump. Solutions?

THe power and grond wires from the battery have been an issue on that truck for years. Firts - the ground wire goes to the aluminum accesorie bracket on the front of the engine. oddly enough it will supply enough of a ground to run the engine,fuel pump,lights,radio ect. but not even click when the key is in the start position. usually when this happens the little wire coming from the battery ground wire going to the fender naxt to the battery to a 10mm bolt is burnt also as it usually tries to carry the current to start the engine but cant so it gets burned up. Move the ground wire from the accessory bracket to an intake manifold bolt on the right front of the intake OR the thermostat housing bolt where the pcm wires are connected. make sure you clean the bolt in which you move the cable to.
\015\012 now.... another problem is that the + and - cables can corrode inside of the casing and you can not tell sometimes. sometimes you will see a swollen spot or bubble in the cable where is has corroded and is no longer making contact inside the insulation. Once again until it completely fails inside the insulation it will run some of the vehicles accesories. I was stumped on one of these at the dealer once and never forgot what i just told you. FRUSTRATING so dont feel bad. I hope i have helped you - Good luck! Scott
Clutch pedal switch? Is that the part you jumped? If not, then you can unplug it and hook a jumper wire to see if it works. I would not recommend leaving it like that though as it would be unsafe if a person did not depress the pedal and started it while in gear.
\012You can also hook a test light to one side and see if there is power when the key is turned. That would tell you is you're getting power from the ignition switch.
\012If you have determined it is not the clutch safety switch then go to the starter and test the small terminal (s termial with the wire) with a test light while trying to start. It should light up.
