If you changed your plugs, etc. and know that you are getting a good spark then it's really only 2 other things to check. The compression in that cylinder and the fuel. Check fuel pressure with gauge hooked up to Schrader valve on fuel line next to your distributor ( it has a black threaded cap on it). If pressure is good then you have either a dirty or clogged fuel injector or the injector quit working. Let me know what you find. Anytime you get a misfire in a particular cylinder, you should always check for spark, fuel and compression.

What are the signs that my alternator is not working correctly
When sat in the car and it is running , face the front up to a garage door or wall with the main beam on. Put your foot onto the accelerator pedal with the car in Neutral . You will see the Headlamps go much brighter if the alternator is OK . If it is faulty they will stay quite dim.

I have a 1998 g_m_c jimmy 4.3 liter when it's
check to see if the cat converter is partially plugged if you can just unhook converter and run see if power is good if ok replace converter you can also do an exhaust back pressure test if you have the back pressure gauge but if you have replaced fuel filter and all i would say that it is quite possible that is your problem

I have a 1998 gmc jimmy 4.3 6cylinder 4x4 I blew
What I've seen done to test an injector is to pull it, and swap it for another cylinder. If the miss moves, then the injector is bad. If the miss stays on #5, then the problem isn't the injector.

My 98;jimmy will not start engine turns but will
check for spark at the plugs then check for fuel. if one of these are missing the car won`t start. common problem on some of these was the ignition module in the distributor and sometimes the pickup coil wires would break. another thing to check is the distributor cap and rotor for damage like a cracked cap or burnt through rotor. fuel pump were also common.

My 98 jimmy is not starting up . Engine turns but
Pretty sure I know what is causing this. common issue in GM's. Your security system failed .this has happened to me before I found a module that can bypass it and your car will run again and its very inexpensive and you can do it yourself. check it out see if you think its it. your car make and model are on the list for this issue.

Backup lights won t come when in revers
Check the fuse, then the bulbs, then the switch on the transmission. The switch could need adjusting, try moving the gear lever around the reverse point to see if the lights come on, if they do the switch may need adjusting.

Starter engages when in park
Sounds like you have a column shift? The nylon bushings are probably wearing out and shorting the ignition switch. You probably need to rebuild your steering column or go to salvage yard and replace with used one.

Rear pinion removel on a GMC Jimmy 1998 4x4 to
Pull the rear cover, remove the axles, remove the carrier assembly, drop the drive shaft off the yoke,remove pinion nut, remove the yoke and knock the pinion out with wooden or brass hammer. The pinion bearing will have to be pressed off and on with proper shim. reinstall with new crush sleeve. There is alot specs and readings yoy need to follow so it is best to get a repair manual and follow it to the tee.
