A few weeks ago jeep started skipping and I replaced the fuel pump regulator. Improved somewhat until this weekend when it got worse and I then lost power to the ignition system and fuel pump. It turns over but there is no spark there. What could this be and how do I fix?

Check to see if you lost injector pulse also. If so, check and the the Crank Position sensor.

If everything else is ok? The computer has to have the cam and crank signal or it won't start.

Any applicable trouble codes? Some makes and models, you can get some codes by cycling the ignition switch. You turn the key just till the dash lites come on, no further. You cycle the key, on--off, on--off, on, then the mil on the dash starts flashing, you count the flashes to get the codes. Your looking for two digit codes.
