Hi Lannie, I'm glad to help. That's a tough one because you can't remove the tumbler if your can't turn it to the proper position. Here's something you can try, it's worked for me many times, but sometimes it doesn't. TAKE, a spray lube and spray it directly where the key goes in. NEXT put the key in like you going to start the car and take a hammer CAUTION: Just tap on the end of the key carefully so you don't break the key, hit it directly on the end of the key. Then try to turn the key, if it turns then you can remove and replace your new one, IF IT DOESN"T, repeat the procedure until it turns. Hope this helps and have an awesome day Lannie!

ever do a 60k tuneup this decade.
if this is knocking combustion detonation, the engine will self destruct soon. ping or knock is cause by lean mixtures and very hot combustion, all very bad, do not go up hills that makes this worse.
i say get a shop to check it out. before it gets too costly to fix.
easy on any 91 car.

Great question. On a 1991 vehicle, that's all what the computer was about-engine management functions, that and some emission requirements. Turns the pump on, runs the injector circuits, and figures spark timing. Only has so many sensors, and so many output controllers. If your spark is good as in a blue, snapping spark, and the injectors are pulsing, and nothing wrong with the pump circuit (check your fuel pressure to verify), then the computer has that much going for it. Even so, a diagnostic flow chart could lead you down a long list of tests or things to check before it arrives at the computer as the possible problem. And when all is said and done, they will often say "Substitute a known good computer and see if problem persists."

please say what you are trying to do.????
what does stuck mean.? (rusted to frame ,clamps bad? what?)
the lines have fittings and are clamped to the frame.
if messing fuel , i recommend getting a REAL FSM
and reading that , , and old 91 car will need lots of service
and a real FSM will be huge pay back and learned fuel safety.
see skeleton here.
http://www.fixkick.com/INJECTORS/depressure.html

first learn the safety issues.
the attack. and live.
lots of way to get in trouble,

if it has one at all its in the fuse box.
here , ill login to all data.com and see ....you can too.. for sure.
my answers are all for USA spec, cars.
2.5L or 4.0L, 4.2L engine.... that is always first. so i look twice.
maybe both
open car hood
see fuse box, this MAIN.
see top left corner relay , i think its there.
why not post symptoms.?

that box is called the power distribution, center
next to battery
the lid comes of and relay is in there, with all the huge fuses.

if you have a volt meter we can find the cause is 5min work
in fact, less if we hot wire starter. in 1 seconds work.

check the cv joint rubber cover and replace regrease if its busted open..

1991 Jeep... | Answered on Dec 23, 2013 | 49 views


Most likely yes. One thing about the older Jeeps is that they did not change the models much from year to year. If the two jeeps had the same engine, they are probably nearly 100% interchangeable.
