93 2.3 slow crank but wont start...?
 

i have a 93 ranger 2.3 5sp 170k it will crank slowly but not start. i started it one morning and by the time i came back outside to goto work it was shut off and wouldnt start back up... it has spark and is getting fuel ive tried to jump it still nothing.... ive replaced the clutch safety ignition switch and also a coil pack... battery was bench tested also.

Thanks
