Hey guys everytime i drive my jeep for a couple hours or more when i go to start it starts but will not accelerate or anything. It shakes and eventually runs out of fuel and stalls.If you wait a half hour or so it fires right up. Any help im thinking maybe the fuel pump has a weak return/check spring? By the way its a '93 g.c 4.0L laredo thanks.

 

I would say that your fuel pump is on it;s way out.

 

I bet its the CPS, or when it stalls again, have someone start the jeep while you hit your gas tank with a block of wood. If it does start while hitting the gas tank then its the fuel pump.

 

block of return line.if ok change pump and filter
