If your ignition switch is bad in your steering column, and the starter does not engage when the key is turned forward, then this is a quick fix for you.
BE SURE THE BATTERY IS DISCONECTED BEFORE YOU START WIRING. You can run some heave gauge (18 plus, and about 12 feet of it) wire to the top mount and the rear mount on the starter solenoid (one end of the wire to each, making a loop) Run the wire into the interior of the truck, and then install a toggle switch in the loop of wire. You will still have to turn on the key to engage the motor, but it will not start until you flip the toggle. That should get you by until you can replace the ignition switch in the column.

Can I install a push button start on my 94 c1500 suburban?


Sure can. cut the yellow wire off the ignition switch under the dash. Run a fused wire (40 Amp is good) from the battery to the push button. Put the yellow wire to the push button. Beware though, you are bypassing the neutral safety switch. It will crank anytime you push the button.

1993nissanpickup d21try startin but just click new battery


check your ignition switch solinoid, it could be shot or check your starter relays and fuses, check the theft prevention switch just under the ignition cylinder. there are multiple things that could be causing this problem, but if your like me, you can just bypass all the starting relays for the starter and run a switch inside the cab to push that runs directly from the battery to the starter, and install a push-start button on the dash. let me know if this has helped you any, good luck.

I start my car but it immediatly shuts off and the theft sys light flashes could this light be the reason?


the ignition swith reads the key chip when key is turned, this is a common problem,the ignition switch will need to be replaced, after replacing the swith reprograming will be needed, to program you will need a battery charger to keep battery from going dead, after installing new switch,turn charger on, turn key to crank then release key leaving ignition on, you will see the dash lights, leave key on for about 15-20 min, until you see theft light go out, if light doesnt go out then repeat process,crank for 2 sec, then leave key on 15-20 mins until security/theft light goes out, hope this helps.

I have a 1993 buick lesabre. The security light is flashing and will not start. I checked the fuse it was ok. I tried our other key and still wouldn't start.


there may be a broken wire from the ignition swith going down the steering column,theres two sensors at the begining opening of switch, sometimes they get stuck and dont pop back out, in turn it doesnt touch the chip on the key and cant read it,take a look with a light use a small pic and push lightly on them and see if the y push in and pop out, if they do then replace ignition swith,theres a way to bypass,use an omh meter and measure resistance of key chip, then buy a resistor with the same value,and connenet to wires from switch under the dash,cut wires and put conecting the two going to switch with resistor connecting them together,heres a diagram,193b32f.jpg

the small wire that has a boot that pushes on to the screw is the control to close the solenoid.unless the solenoid is shorted,the starter should not run

The fuel pump has been changed, however it does not pump fuel. A by-pass swith was installed and it works. What makes this happen. Could it be the ignition switch causing the problem. When the by-pass...


Chances are the fuel pump relay has died, and the bypass switch is turning it on in the absence of the relay. Replace your fuel pump relay and you should be able to get rid of the bypass switch.

Starter switch


You'll connect one side of the button to constant 12v. like the battery positive and the other side of the switch will go to the trigger wire of the starter. This is the wire that tells the starter what to do.
