My 1997 jeep grand cherokee Laredo 4.0l is hard to start at times and will just die after a few seconds of running we replaced the crank sensor, rotor o2 senser we are getting ready to buy a new computer. Any ideas before we get it?

Have you checked fuel pump pressure when this happens? Has the fuel filter ever been replaced?

Im not really sure if the filter has been replaced. But the main problem seems to be with the spark. It runs fine when ever it wants to. My dad is running out of Gg on what it could be

Based on your description, I would recommend that you check the fuel pump pressure.
