would codes 14 and 24 cause these sympthoms?

i ran to the grocery store a few minutes ago,jeep ran fine. put the groeceries away and was going to go to the gym. Jeep died as I was about halfway out of my driveway. The engine will start,but will not run longer than 2 or 3 seconds,even if I rev it up,and it doesn't rev up that well. I pulled the codes and got a 14 and 24(TPS and MAP sensors). Would this be correct,and why would they both go bad at once? I did replace the fuel pump yesterday,but I have driven about 30 miles since then without problems,and I have good fuel pressure and I can hear the pump cycle. Just looking for ideas before I go spend money on sensors I don't really need. thanks,Ben

I also noticed that after the engine dies,the fuel pump cycles again. i am not sure this is normal,as the jeep has never died on me the year I have owned it. Is this normal? I tried some searches on here about my problem,but didn't have much luck. I really don't want to start replacing sensors with out cause. thanks for the help,Ben

am I the only one to experience a problem like this? still looking for ideas. thanks for the help,Ben

ok,here is an update: I swapped the TPS out with one from a 96 4.0 I have in the garage,same result. the engine will run if i keep my foot in the gas. I am talking 2000-2500 rpms here. as soon as I let off the gas a little bit,it will die and not respond to throttle if I give it more gas to speed it up again. I am lost as what I should try next,like I said the only codes I get are 14 and 24,and when I disconnect the map sensor and start it,it runs way rough,so I am thinking the map sensor is working. I am about out of ideas and I can't afford to have it towed and let a shop fix it thanks for any help given....Ben

try tapping the map sensor with the engine running badge714

badge714,I would if the engine would stay running long enough for me to get out and hit it thanks for the suggestion.

I just went and pulled the codes again after I swapped the TPS. now the only code I get is 12,but the engine still runs the same. what would make the MAP code clear itself up? thanks

thanks badge714,but that is a site for an inner pinion bearing kit
