Mannnn thank you for this video I bought this part and returned it because I didn’t know to take the top and bottom harness and transfer it to the new switch🤦🏾♂️🤦🏾♂️ guess I’ll be buying it again🤣
Thank you for posting the video.
You bet!
WoW! long winded! Thanks,
Comanche Out!!!%
Thanks for the video, I have a Astro van with fuel pressure and spark but still won't start, thinking that it may be in the ignition switch, not allowing the injectors to turn on, Were you getting spark before you changed the switch?
Yes the vehicle had spark and fuel. I could manually bypass the lock-out cylinder and get the truck to crank and start. The internal contacts of the ignition switch were not completing the start circuit.
Thanks very Much, I'll wait on the ignition to come and hold off on tearing the injectors out lol, What a mess, haha!
One more question, before ripping out the ignition, were you able to get it to crank over with the key? I stick the key in and it cranks, just wont fire.
@@MattBroquard It would start with the key but cranking was very intermittent. The column (tilt adjustable) would have to be tilted at just the right angle but after time that too didn't work.. The switch just gave up completely and wouldn't make any contact internally.
I had this problem. Changed the ignition switch. The car fired up and everything worked. My parking brake was stuck without working release latch. After literally 30 seconds of a video, I figured out how to release it. I go to start the car again and nothing, no power, no start. My dome light wouldn't even come on. My question is What's destroying these ignition switches? This one ran for less than 10 minutes before breaking. Any suggestion would be thoroughly appreciated. I dont get it, but there has to be an answer. Or am I just personally cursed?
One or more wires have high resistance if you're not popping fuses. You can test the ignition harness on the column between the connectors & replace just that column harness for relatively cheap.
Hello, You said that you changed the ignition switch because the dash and or dash lights did not work. Even though the dash did not work, were you still able to start the vehicle ?
Yes, but it was very intermittent when the vehicle would start.
Can you start a Chevy s-10 with a bad electrical ignition switch
Yes. On the starter solenoid you can jump the ignition post to the 12V post from the battery.
@@WreckEmRacing Thanks!
What is the part number? I have 91 s10 tahoe pkg.
For a 91 the OEM Interchange Part Number is:
633.GM8394
Torx head screw socket size.?
I can't answer the exact size off the top of my head. I know there's a bit set from Harbor Freight that covers all of the smaller fasteners for relatively cheap.
4mm
T-15 torx, or e4 inverted torx.
Hi , how much did you pay for your part?
After wasting time with the $40 cheapos I only buy the OEM switches; they're around $100-$150.
Don't mean to blow up it up here on the comments but your key when cranking it forward didn't always start the vehicle? Thinking, I have a Separate issue. I don't have any problems cranking it over, just cranks and cranks and wont start. As of right now, my vehicle is acting like the fuel injectors are not getting fuel. Brand new fuel pump with 60 psi, so i know something deeper is going on.":Be nice just to replace the ignition switch and have some Success, but 'm not sure it's going to be that easy!
If the engine cranks over consistently it's more likely in your fuel or spark. Test the spark with a simple spark tester that plugs into the plug wires. Distributor cap and rotor are a likely culprit and a cheap replacement.
