Injector Ohm Reading
 

Replacing valve cover gasket in the morning and will check to see which injector is bad while I'm there. Does anyone know what the Ohm meter should read between a good/bad injector?

less than 1 ohm and greater than 0 ohms usually about .5 ohm is good injector if it reads 0 ohm or over 1 ohm bad injector.

bad injector coil/electrical part. doesnt neccessarily mean the tips are shot. you could get 0 hm reading but still have shitty tips or plugged or stuck.

question about the injector. would a truck run good when it warms up with a bad injector? when it is cold it runs good then it runs like crap. then if it is warmer outside it goes to running ok. i have changed the lift pump and filter twice. i have talked to some mechanics that thought it might be the injectors. when it is cold outside it never goes to running ok.

Checked the Ohms on the injectors this morning. All but #4 read 0. #4 read
.4 Ohms. Funny thing is is that most of the time the truck runs like a top. However, today, was one of the times I had a bad miss out of the motor. If all but one were showing bad seems like it wouldn't run at all. Am I right?

Bump!! Anymore comments on this?:(

When mine went bad in the 07 company truck, all were between .07 and 1.2 except for the bad one which was 35.7 and as the engine cooled it went down to 10.7.

Turn the ignition off.
Disconnect the pigtail nuts from the suspect injector. Using an Ohmmeter, check the
resistance between the solenoid posts of the injector.
NOTE: Be sure to zero the ohm meter prior to checking the injector circuit.
Is the resistance less than 1 ohm and greater than 0 ohms?

Yes ! Go To 4
No ! Replace the fuel injector
