Replaced fuel pump 30Kmiles ago. Was a big job, as I had to remove the tank. Now it "seems" to have the same problem. No start. But it is not the ignition system. Tries to start when injecting starter fluid in air manifold. Question: What is easiest way to check for bad fuel pump or bad filter or relay? AND, is there a way to replace the pump or filter w/o removing the tank???

That fuel filter is in the fuel tank, attached to the fuel pump. Not a very difficult job. Remove the rear seat cushion, then remove the access panel to the pump. Remove the gas cap to relieve any pressure. Remove the ground wire and fuel lines, then remove the filter.
Try tracing the fuel line from the gas tank to the fuel injection. If you are unable to find it then most likely the filter is located in the fuel tank with the fuel pump if equiped with an electronic fuel pump. Some fuel pumps are located in the tank, by the tank, or on the engine. either way if you trace the fuel line you should find it unless it is in the gas tank like I mentioned. Good Luck!
if your fuel pump and relay are new, how about your fuel filter, if your fuel pump is working but no fuel turns out, check fuel pump polarity, if ok, there will be a clogging in fuel lines, take a high pressure air and plug it to fuel outlet in fuel lines test port, allow air to go back up to fuel tank and observe if the air goes, if not, check or change fuel line, if the air goes to tank, direct your fuel relay pin 30 and 87 and check if the fuel runs to the injectors, if not, change a good fuel pump
I had this problem several years ago. Found a new fuel pump for about $20.00. Removed tank and discovered it was a bayonet connector in the wire harness $(70.00) not the motor. I had to lower the drive shaft to get to the fastners which tie the tank to the bottom of the trunk. I still have the motor; will consider selling it. (903 732-3912). - Philip
Fuel pump is bad or plugged fuel filter it seems. Crack the line from the filter leading towards the engine first. If gas starts squirting out fast, you have good pressue. If not the filter is plugged or a bad pump. How old is the fuel filter by chance? If original its plugged up by now
i have a 92 xj6 i just replaced the fuel pump should be the same for yours remove spare tire in trunk there are two straps two bolts take bolts out jack car up there are locate your fuel filter mine was under the rear door drivers side follow the hoses and they will lead you to the two hoses connecting the gas tank there are two pins to remove one on each hose do not loose those trust me they will be hard to find and be aware there is very little space to work in after removing tank the rest is easy remove the pump located in the tank and do everything in reverse also dont forget to replace the screen to clean all the rust out of the tank there is a bolt in the bottom of the tank to let all the debris out good luck
