We clean the trottle body put it back and key code and injector light stays on and wont start

Ok that to me sounds like you need to clean the throttle body it easy buy carburetor clean just srap a little inside the throttle body n clean it that will help you the problem is the trottle body gets dirty sticky and won't idle good n stall remember don't put to much. Just a few spats inside the when you put the hose back it might take a few minutes to start because of the amount also don't accelerat it to high when it start good luck

At some point the computer has detected a fault (probably the missing throttle body while you had it off) and has thrown an error code. Suggest you get the error code reset - that will probably fix it. You will need the reset device to do this or get a dealer to do it.

Cam position sensor tells computer when to synchronize injector pulse. Have you checked for trouble codes?
Check injector fuse. Injectors should have constant voltage supplied when key is on.
You didn't give year and model. Injectors are pulsed when the engine computer internally grounds an injector. You may need to check injector circuit.

Dodge Ram 1500 - 2002 4.7


After my radiator blew, this all started..


The truck runs well if you don't accularate quickly but
if I try to excellerate (Kickdown) at 3000rpm`s it doesn't take it,


I had verious codes when I put the OBD on the motor, so far I have changed the following parts
Coil,
8 New full injectors,
map sensor,
sensor,
cleaned all wires,
verified and cleaned the spark plugs
Verified all the wiring, grounds, etc.


Could it be the trottle body, transmission sensor (cellenoide sensor) or other.


Any suggestions would help


thank you all in advance

I DON'T KNOW OF ANY CODES THAT TELL YOU TO CLEAN THE THROTTLE BODY. THE LIGHT WON'T GO OUT BY ITSELF UNTILL MANY STARTS AFTER A PROBLEM IS REPAIRED. IT MUST BE CLEARED WITH A SCAN TOOL. FIND A REPUTABLE GARAGE, TELL THEM YOU'D LIKE TO REPAIR IT YOURSELF, AND TELL THEM YOU WILL PAY FOR AN ACCURATE DIAGNOSIS.

Remove the vacuum line from the fuel pressure regulator and inspect for fuel leaking into the vacuum line. There should be NO fuel.
The regulator is located on the upper intake manifold and is easily accessible.

REPLACE FUEL FILTER.+ AIR FILTER.CLEAN FUEL INJECTORS.THEY COULD BE DIRTY .LEAKING WHEN ENGINE IS OFF FOULING OUT SPARK PLUGS.FILL GAS TANK UP.PUT A BOTTLE OF FUEL INJECTOR CLEANER.IN GAS TANK.DRIVE AROUND SO CLEAN CAN CLEAN INJECTORS.IF YOU STILL HAVE SAME PROBLEM.HAVE CAR SCAN TO SEE IF IAT ECT MAF SENSORS IS WORKING.

change the throtle air idle valve on the inlet manifold.

bad throttle body or injector,

sounds like an antitheft system malfunction - check to see if light stays on after you remove the key
