The Multimeter has several functions.It test voltages [a/c, d.c. (+ plus, - minus)], then the RESISTANCE test to test 'ballast resistors". If the tester has a on-off switch, make sure that the scitch is OFF. If you can disconnect one side of the resistor, do so !! Place (+plus) side of probe on DISCONNECTED side, turn meter ON, place other side of probe (- minus)on other side of resistor.You should mesure the resistance you see written on the ballast. IF YOU CAN'T DISCONNECT ONE SIDE, just follow the same rules WITHOUT DISCONNECTING one side.
NOTE:: Rustyrooster, what Salkim08 said is true, but he simplifed it. Connected to the ballast on either side or both sides is a circukt (ckt.) that could effect the measurement.

Ok this is going to sound stupid but I recently broke down in my 1988 jeep wrangler 4x4 I changed the fuel pump and sending unit not thinking that I had blown a fuse which I did lol now all is fixed except...

do you have a multimeter or a test light? check each fuse and make sure there is power on both ends.
putting the fuses in wrongs places can cause them to blow or wiring to overheat if they are rated too high.

Keep blowing a fuse under hood in 98 jeep wrangler that will stop me from getting fuel and replaced the fuel pump after i got the problem, and it still keeps doin it. would run for a min or two then fuse...

Measure resistance between the fuse box and the fuel pump. You most likely have high resistance in the wire. Also check between the fuse box and body ground for resistance

My 95 jeep wrangler sputters when I accelerate. I just changed my fuel filter and still runs the same.

For starters, fit a new set of spark plugs and test the HT plug and coild lead for high resistance. If you have the fuel injected engine, test the fuel pressure in the fuel rail and if this is ok, have the injectors cleaned and calibrated. If still aproblem, remove the negative battery terminal, wait a minute or so and re-fit it. This will re-set the engine management computer back to factory defaults. These things should do it.

Does a 1994 jeep wrangler have a ballast resister for the fuel pump? where is it?

Pretty sure it does...if you have one it should be on the fender or firewall near the master cylinder. It's about three inches long made of ceramic. with a wire connector on both ends.

93 wrangler 2.5 will crank but won't start. I pour gas down the #1 cylinder and put the plug back in and it will crank for about 8 seconds then sputter to life and idle and run fine. Shut it off and try to...

Yes...check the pump, filter and output. Also check the ballast resistor for the pump. Stop pouring fuel into the cylinder...instead, use carb cleaner and spray into throttle body (excess fuel in one cyl will contaminate your engine oil). If it runs normally after you get it started likely the pump is good (unless you have problems at high rpm's under power) Regulator is likely good as well...default is to more fuel not less.

92 wrangler seems like it isnt getting gas

Only careful testing will give you an answer, but check the ballast resistor on the drivers fender near the firewall and master cylinder (ceramic block ) they sometimes can do that. Testing requires using a digital multi-meter and following instructions in any decent manual. I know it's a pain to do but it avoids expensive guessing.

Jeep Wrangler 1995 coil loses power when fuel pump shuts off!

No, the ignition coil has nothing to do with fuel pump.
