Does the check engine light come on when you turn the key switch on ??
If not, you should check the fuses for the computer next.

Check to make sure your intake system does not have any leaks in it that is allowing extra air to come in past the MAF sensor.

2000 jeep cherokee starts slow. doesnt idle well, and radio clock resets...i installed a new battery, new starter and checked all ground on engine. what is it??


It sounds pretty obvious that it is losing battery power. That is about the only thing that will cause your clock to reset itself. I would be taking a HARD look at the battery cables and connections. By this I mean to do some actual circuit testing like performing voltage drop tests.

Also, since your vehicle is an OBD compatible vehicle (which means it is capable of self-diagnosis), it would also be a really good idea to perform a FULL computer network scan to see if there are any clues there.

By "FULL" I mean scan ALL the modules and check the data - NOT just hook up a generic code reader and try to pull codes. If the PCM is losing power you will not get any generic OBD fault codes from a code reader. However one of the other modules will most likely report communications faults with the PCM. Cheap generic OBD code readers cannot perform these functions.

check fuse number 5 in the passenger compartment fuse box, it is a 10 amp, that is the OBD connector power supply, if that fuse is good just run power to pin number 16 of the connector, this the bottom row of pins last one on the right.

You'll need an OBD I code reader or similar reader to pull the codes. You can purchase from autozone or online.

There are a lot of things to check:
- check ANY wiring connector at the engine incl. ECU
- check fuel pump pressure (45 to51 PSI, 2,95 to 3,2 at), there is a connector on the right fuel line, between injector 3 and 5.
- check the sensor on the crankshaft if installed the right way.
- check injectors for leaking
- check your vacuum system careful
- check your TPS
Check your OBD II-System, all functions Engine and Freeze Frame, Emission control etc.
You can check the OBD-System first. Connectors and Software for PC/Laptop are sold for $ 100 to $ 170 incl. OBD-connector and wiring. This is a one time investment that saves you lot of costs and time

Fuel pump or filter. I have the same problem with my 95 and am in the process of changing out the fuel pump. Already did the filter (not the problem). Hope this helps!

OBD II Scanner TP180-CAN Error.


if the obd 2 reader won't scan and it will not run it is probably a computer problem could even be a wiring problem to the computer not sure if you can get those checked or bite the bullet and buy one. call the jeep dealer in the morning and ask if they can check a computer to see if it is bad
