Start with basic troubleshooting: fuel pressure, compression test, any codes/check engine light?

Did this start suddenly or gradually? If suddenly, was any work done on the Jeep that seemed to cause it? Again, have you done a compression test?

try this, its free and it take 10 seconds to do...my guess is it will surprise you

adjust your t.v cable

start with that first
