Bobby12300,It has been awhile since i have worked on this car but, if you want it done right away i would suggest going to a pep boys or a auto zone. Asking the clerk for a injector controller layout to which they should be more than happy to help print off the layout. I will keep researching this answer and if i find something i will post it on here. -Thank you

You mean P0202 , an what engine does yours have ? 2.6 L ,3.3 L , 3.6 L or 5.7 L ?
DTC P0201, P0202, P0203, P0204, P0205, or P0206
The engine control module (ECM) enables the appropriate fuel injector on the intake stroke for each cylinder. Ignition voltage is supplied directly to the fuel injectors. The ECM controls each fuel injector by grounding the control circuit via a solid state device called a driver. The ECM monitors the status of each driver. If the ECM detects an incorrect voltage for the commanded state of the driver, a fuel injector control DTC sets.
Test your fuel injector for cylinder #3 ! Do you know how to do that ?
You probably changed computers for nothing ! Check out this video on testing fuel injector circuits an checking computer driver that controls the injectors , Oh , by the way P0300 P0301 an P0302 are misfire codes , P0300 is a random misfire an the other two are for cylinders 1&2

Replace fuel injectors


Disconnect the battery. Ground the Injector circuit to discharge any stored energy. disconnect and remove the injector rail which should pull the injectors from the intake then remove the retaining clip on each injector to be replaced and replace them one at a time and reverse the process to put everything back. If you need further directions on removing the individual injectors I highly recommend the Haynes repair manual on your vehicle.

Fuel injector. The car seems to drop a cylinder. I replaced the plugs and it ran well for about five minutes. It then started to miss again. I think number 3 injector is bad. How do I replace one injector.


FIRST YOU NEED TO RELIEVE FUEL SYSTEM PRESSURE BY REMOVING FUEL FILLER CAP THEN DISCONNECT FUEL PUMP HARNESS OR UNPLUG FUEL PUMP CIRCUIT RELAY, THEN START ENGINE LET IT IDLE UNTIL DIE LACK OF FUEL.TO REMOVE FUEL INJECTOR YOU NEED TO REMOVE FUEL DELIVERY PIPE WITH FUEL INJECTORS AS A ASSEMBLY TO REMOVE FUEL INJECTOR.YOU NEED TO TAG NUMBER ALL VACUUM HOSES AND PCV VALVE,NUMBER TAG FUEL INJECTORS WIRE CONNECTORS SO YOU CAN PUT EVERY THING BACK IN RIGHT PLACE.

My 2000 intrepid will no start. My husband has recently replaced with a new alternator. The car ran fort the 2 days.After i shut it off it then never started back. My husband then replaced the fuel pump...


Check injectors for operation of solenoids. Put long screwdriver on injector and hold ear to screwdriver while someone cranks engine. If injector clicks once every 2 revolutions, injectors are working. If working, check fuel pressure at rail. If low, replace fuel pressure regulator (get back to me for instructions).

If injectors not clicking, the powertrain control module is not sending signals to the injectors. This could be caused by the camshaft position sensor or the PCM itself.

If you have more questions, please let us know.

After removing the fuel injectors and rail to remove the manifold, how do you reinstall the fuel injectors?


the same way you took it apart. put a little grease around the rubber seals so they will slide in easier. just tap on the fuel rail while lightly tapping it into place.
