How do you reset the computer for 1995 jeep grand cherokee changed the starter yesterday now it only runs 10 seconds and dies some one said to reset conputer but i dont know how tried the internet no luck please anybody help thanks ken
Ken to reset your computer/ECM JUST unhook your Negative Battery Cable for a minute and hook it back up. I recommend doing that before you get into a lot of troubleshooting or any time you replace anything electrical like sensors and such. Hope this helps you.
Have you checked the fuel pump relay? A relay is like one in your home and if they get to warm for any reason they shut down the power that should be going through it. Just a thought that I didn't see mentioned.

You probably disconnected the battery to install the new fuel pump. The alarm system will act in this manner after reconnecting the battery. Put the key in the door and lock the door. Then unlock the door. Try starting the vehicle now.
Check your fuel pump relay.
Did you check for trouble codes? Cycle ignition key t
They have a built in alarm system i reset mine by puting the key in the drivers door key hole and turning the key to lock and un lock the door
Ok i had the same problem with my 93 jeep. i replaced the fuel pump, the fuel filter,fuel regulator, and the brain( computer). spent alot of money and it has still starting and dying. Turned out to be a short in the dash from the fuse box. came across the short by accident, got mad and hit the dash above the glove box one day and it started right up. Hitting the dash worked everytime, and i drove it like that for a good two months before i could track down the short and fix it. I don't know try it out and let me know.

dont know how to reset computer on 1995 jeep grand cherokee 5.2 ltr limited edition please help thanks ken
Unhook the negative battery cable and place it on the positive battery post for 60 seconds then put it back on the battery.
turns over when you turn the key, but as soon as you let go of key it dies.
Well slap me silly!!!! somehow didn't even think of that!!! glad its fixed!!!!
New is good, but if theyre wet that points one way , dry, another problem entirely!
Wasn't too concerned with that...what do the plugs look like?
Fuel pressure is a bit high but could just be a slight innacuracy in your gauge. What does it read with regulator vaccuum hose disconnected? Is regulator on the fuel rail or on the pump? (should be about 39-41) Are plugs wet or dry when you remove them after cranking? Are you checking spark at plugs or at coil?
starts and dies or what. does it happen all the time or just sometimes.
Cycle key from off to on 3 times with out starting vehicle then on the 3rd time leave key on and count the number of check engine light flashes. A common cause of your problem is usually caused by a bad CRANKSHAFT SENSOR. Good luck
