What should Duramax injector balance rates?
When viewing the rates, a cylinder with (+) means that its injector is using more fuel than the average fuel rate and a (-) translates to less fuel. GM states that balance rates should be no more than plus or minus 4 (+4/-4) in park at operating temperature.
How much does a Duramax injector circuit cost?
The wiring on the injectors is very simple: One wire powers the injector while the FICM fires the injector by grounding the other. The recommended resale from my supplier on these remanufactured injectors is about $1,600 for the set of four.
Is there a warranty on Bosch Duramax injectors?
We are so pleased with the performance of these Brand New Bosch Injectors that we back them with an unlimited mileage 3 year warranty. You will not find a better deal on the web and even if you do, please contact us and we will beat it! Replacement injector line retainer clip and injector line retainer bolt available separately.
Is it easy to do pinpoint diagnostics on a Duramax?
Sure, it’s easy to talk about pinpoint diagnostics, but with the fourth pin-out on the FICM C1 and C2 connectors yielding the same results, I really didn’t have any place to go with the diagnostics except to replace the FICM as recommended by service information.
What is the code on the Duramax fuel injector?
Low and behold, the P1249 had returned as it had numerous times before. But the only code displayed was a P0205, which indicated a circuit fault on #5 fuel injector. Working quickly before the cylinder heads warmed up, we removed the FICM connectors and repeated the pin test.

How is resistance measured on a Duramax injector?
Since .3 ohms is a very small resistance, the ohmmeter leads must be clean and the meter must be perfectly “zeroed” by crossing the leads and pushing the “relative” button. If the ohmmeter doesn’t have the “rel” feature, jot down the leads’ resistance and subtract that from the total reading when measuring circuit resistance.
