The check gauges light is normal because at 400 rpm it isn't running fast enough to build sufficient oil pressure. I am guessing maybe a vaccum leak???

SOURCE: jeep starts and idles perfect no acceleration,

Sounds like the catalytic converter or muffler are clogged. There isn't much exhaust at idle, but when you accelerate your exhaust volume increases, thus if your catalytic converter or muffler are clogged the restrict the exhaust escaping out thus causing an excess of back pressure which won't allow the engine to breathe normally.

Do i have to take the engine out to change the oil pump on a 98 jeep wrangler 4.0 I-6


Actually oil pumps in the JEEP 4.0 are notorious for going out or wearing at 1500000 miles as you will find in most blogs and topics. And the 4.0 is a very solid motor capable of 300,000-400,000 miles if taken care of,unless driven hard I wouldnt say it would be worn out!

98 Jeep Wrangler turn signals and flashers don't work


The tail lights on the 98 use the screws that hold the light to the body of the jeep to ground the lights. Chances are the wholes that the screws/bolts goes into have a coating of rust around them and are stopping the lights from grounding. This may not be the solution but you need to eliminate this from your list.
