How to test ignition coil on a 1998 chevy k1500 5.7l v8

What engine does it have? V-6 - V8

Looks like one bank of cylinders are dead.

well if ur not getting spark and u changed all of the ignition components lets think about the computer in order for the ignition to work you have crankshaft position sensor that fires the fuel injectors and the spark change that and if still nothing then change the camshaft postion sensor that sensor tells the computer that the 1 piston has came all the way up and it tells the crankshaft sensor to do its thing

Could be ignition switch is bad, does distributor ever have power going to it?

sounds like an intake or a headgasket problem

See if you're missing fuel or spark.
Does the fuel pump buzz for about 2 seconds when the key is first turned to ON? Do you have about 60psi of fuel pressure? Are your fuses good?
Then you can probe injector wires and have the ignition module tested at an Auto Zone.

Pull a coil wire, do you get spark? Do you have power to the coil? Again, test the ignition module.

on a chevy carb engine you only need to run a switched 12 volt to the distributor.

it could be anything but i would say you should check the ignition coils first. you can do this by testing the resistance in the coil packs. make sure the engine is off and the key is not in the ignition. if you set your voltmeter to ohms take the 2 ignition wires off of one coil pack. touch your voltmeter lead wires to the 2 posts on the ignition coil. it should read 4000-8000 ohms if you have a bad coil it will usually be close to 0 ohms. do this test for all coil packs. each coil pack ignites 2 cylinders so if you have a v6 you will need to test 3 packs and 4 packs on a v8

To gain access you have to remove the ignition coil pack. There are only 4 10mm bolts holding it on. Also remove the cross over to have more room.

This is most definitely ignition related or fuel injector related.

not likely a fuel issue,
try running it in the dark of night , no lighting and look for sparks ,
have the ignition coil tested , be sure it has good ground.
pull each plug and watch the spark ,does it maintain the blue long arc.
tune a am/fm radio to the sparks ignition sound an listen to it
a portable walkman can lead you to the faulty spark,
or just have them monitor the spark at the shop.
