p0340 is the cam shaft sensor, this will cause it to cut off while driving, hardtime starting, p0351 is the ignition coil A primary/secondary curcuit mal function. p1391 is ignition system misfire, this could be plugs, wires, or coils. first of all have the cam sensor changed and it may correct the rest of the codes. when fixed turn light off with obd2 scanner. if you do not have one, then any auto parts store will erase the codes fo free of charge.

98' jeep starts sometimes


The next time it fails to start, you'll need to start crossing off the possible causes. Is it lack of fuel or lack of spark ? Is the asd relay working, and so on. Once you narrow down the causes you can troubleshoot it better.

My 1994 Jeep Grand Cherokee with the 5.2L is very difficult to start if it has not been run in the previous 6 hours. Replaced ignition coil but didn't solve the problem. After sitting overnight it


Low fuel pressure.
You need to check the fuel pressure on the first crank and watch it as it is running.
Requires a special gauge.
If it were just a starting problem I would say it could be a pump relay, but not if it runs rough for 5 min.
Might be a dirty filter or problem in the tank.

I have a 99 grand cherokee iwas driving about 10


check your fuel filter it could be restricted that won't show up on test. A faulty fuel pump wont show up either...next time it stalls check to see if you can hear the pump running when you turn the key on. (filter may be part of the regulator on top of the pump unit on top but outside the tank)

Check spark first if ok then look at the fuel system.Check if the fuel pump is working continuously when turning the key.If so remove the fuel line to the ejectors and check if there is fuel there.If no change the fuel filter.

Runs rough and stalling


Sounds to be related to a fuel or an ignition issue. Check out the history on the vehicles maintenance. Look at when the last COMPLETE tune-up was. Can check fuel line pressure, for a clogged CAT or defective muffler. If the engine light is on while it is running then you have stored code/s, if so then have them read. This will help you in finding the source of your Jeep's problem.

1999 Jeep Grand Cherokee stalling and not starting


Since you've replaced many of the usual suspects (fuel pump etc.) you might want to look into testing or simply replacing the crankshaft position sensor or the camshaft position sensor. If you intermittently lose one the these signals it would cause the problem you describe.
