Question about 1990 GMC Sierra

1 Answer

I just bought a 1990 GMC Sierra 1500 and didn't realize this problem while on the test drive. The key won't turn the ignition all the way back to the lock position, it stops about a third of an inch before the lock line. The key will come out perfectly fine where it does stop at but you can turn the truck on without the key in the ignition now without any problem at all. My truck isn't really steal-worthy but..it's kind of an awkward problem I'd like to fix or have fixed if that's not possible. Is it possible it's just gummed up? Is my ignition #$%^ed? Thoughts?

Lock cylinder needs to be replaced. It's kind of a pain to replace - steering column apart, etc... Most parts store carry replacement - note you will now have 2 keys for your truck - outside locks & ignition.

What will cause misfire in 1990 gmc sierra 1500


If you have replaced the ignition components, that would leave compression and fuel. Your truck has two injectors, one for each bank of cylinders. So one injector could be weak and causing a lean mixture for 4 of the 8 cylinders.
Normally you would perform a compression test on all 8 cylinders and then average them out. Each cylinder should be within 10 percent of the others.

GMC 2000 sierra pick up 1500 sounds like it wants to start but won't turn over. Battery sounds good so I guess battery and alternator are ok. For several years fuel gauge doesn't work and...


It sure could be. But, first...by "won't turn over" you do mean it cranks at normal speed but won't start?
A simple test of the fuel pump is to stand by tank and listen as someone turns key to on. When first turned to on, your pump will activate for 2 or 3 seconds, pressurizing the fuel system, and then shut off if the engine computer doesn't get a cranking signal. Do you hear it come on? If not, then something's not turning your pump on. If you can hear it buzz on briefly, then maybe it's your filter. Another test: Spray a little starting fluid into your intake manifold (remove the big hose going into intake manifold) while someone tries starting it.If it doesn't fire and try to stay running, then it's probably an ignition problem. But if it does fire off, then you know it's a fuel problem-likely your pump or filter. good luck.

I am looking for a wire on my 2004 gmc sierra 1500 that will turn on and off with the key


for what? There is an ignition wire for you radio, but there are many other ignition power wires. Fuse box also is a good place to find an ignition power source, a $3 tester will tell you. I guess it just depends on what your trying to do.
