1994 Jeep Wrangler 6 cyl Four Wheel Drive Manual 121xxx miles

I just bought this jeep from my brother a week ago and that day, it will crank but not start. It is getting the correct amount of fuel. I replaced the spark plugs, plug cables, distributor cap, rotor, and the coil. It gets spark and it started but then two days later, it would crank but not start. To start it, I just spray starting fluid in the air intake and it starts right up. Any ideas?
Do you

Check a manual and find out what the fuel pressure is supposed to be then put a gauge on it and see what it is putting out. It can be pumping fuel but not enough pressure. If the pressure is in specs than it has to be the fuel pressure regulator or injectors. These can be tested with noid lights. Get back to us and let us know what you find out.

I checked the fuel pressure and it is in the correct range. Last night, I installed a new crankcase sensor and it started up every time last night. I must of started it like 30 times to see if I fixed the problem. Well, this morning I went to start it and it isn't starting again. I can still start it with starting fluid so I am in the same situation.

Wow, well the crank sensor would of been my next thought. So after you use a little starting fluid it runs like normal or does it die after it burns what you have sprayed in ( and please be careful, only use very small amounts of starting fluid it can actually hurt if it builds up and then fires). I will check with my other mechanic at work tommorow and maybe have an answer for you. I do not believe this year has a camshaft sensor but something is not reading something. Does the check engine light come on at all? Get back to me please Curt

I ran a diagnostic sunday and the throttle position sensor was reading 82% when the ignition was off, so the TPS was getting high voltage. I unplugged the TPS and tried starting it and it started right up. So today I installed a new TPS and it has been starting all day. Hopefully this solved the problem. Thanks for your help!
