Hey guys! I need some advice. My 96 cherokee sport has been having trouble starting lately. When you turn the ignition the jeep may start right up then die. Then you crank on it but will not start. Then hold the accelerator down about half way and it will start but as soon as you let off the gas it dies. As long as you keep the accelerator down it will stay running then put in gear and it will run fine after that. Any advice would be greatly appreciated.
