Hesitant on starting and 30- 35mph

99 Grand Jeep Cherokee is hesitant to start. It does start up but I have to keep the key turned for a few seconds before it starts up. Also hesitates aroudn 30 to 35 mph. Any suggestions? Thanks.

Sounds like your fuel pump is losing pressure when it sits. Mine has had the pump replaced twice. this is a common problem with these jeeps. Your hesitation at 30-35 i don't think would be related (i'm not real sure though)but it does sound like a fuel delivery problem. How many miles are on your jeep? It might be time to change the plugs and get the fuel system cleaned. Also check your air filter, Good Luck
