My 1995 jeep yj 2.5l 5 speed was sitting for almost 10 years.
First thing I did was remove old fuel and did a complete tune up (oil change,fuel filter,rotor dist. Cap plugs wires.)
Added lucas fuel treatment( full bottle not sure if it was a mistake :s)and fresh fuel and hand cranked motor before starting.
Would turn over but wouldn't fire so I checked fuel pressure to learn the fuel pump was done so I dropped the tank and replaced the pump and she fired up ran a little rough and then smoothed out.
Now after about 50 km of trouble free driving over about a weeks time one morning she didn't want to start but did after a few attempts but now doesn't want to start at all.
Here is what I have troubleshooted
-fuel pressure is 35psi
-has lots of spark
-new map sensor (it threw the code)
-I squirted a tiny shot if starting fluid in the intake and she fired and ran like absolute **** with a fair bit of smoke but stayed running (maybe injectors are the clogged but no code shows.
I'm stumped any help would be greatly appreciated.
