It's always nice when injectors fail high resistance and your diagnostic is just done. My preferred diagnostic order is to check what's easiest first! It varies so much from vehicle to vehicle.
I recently had an old 84 Toyota Tercel throw me for a loop. It uses low resistance injectors and an external injector resistor block. I was getting no fuel into the cylinders. Fuel pressure was good, injector waveform looked good, reasonable pulse width and I could manually trigger each injector and it would drop the rail pressure. Resistance on each injector was about 3. 8 - 4. 0 ohms. Everything seemed fine and I pulled my hair out until someone on iATN suggested I do a current ramp of each injector to see if the pintle hump was there. Turns out only one of the injectors was actually opening. The resistance spec was 3. 0 ohms and all the injector resistances were too high. They were close enough that they'd open open when I manually triggered them because it was a longer pulse, but the short pulse width at idle wasn't enough to move the pintle.

I don't remember any time since I have been following you, Eric, that a car hasn't been somewhere else before it came to your shop. Seems like you always mention something about a previous shop or I am the 3rd shop to look at this. It would certainly appear to me that, at least the locals, would understand what they have and bring their cars to you without going somewhere else. Considering the amount of money paid to other shops, you could have repaired it the first time. No, I have NO trust issues with you. I like Lionel Ritchie as well. GREAT VIDEO!

She didn't quite look the virgin you led us to believe. Maybe we do have trust issues. nah, just screwin with ya. Still worthy of a video, as sometime us DIYers get tripped up on some of the simplest of problems and jump, when we shoulda gave it a think and watched a utube or three before pulling the head. Thx Mr O, always a pleasure.

What in the hell is that air filter Why design the box like that if there’s nothing there Typical Chrysler garbage engineering. Also, looks like someone replaced that coil pack. At least they didn’t mess with the injectors.

What, no happy end Where's my closure How can I sleep at night not knowing if the engine ran fine after replacing the injector
I mean, there could still be a hole in the piston or the spark plug could be damaged.

I'm having while you're in their syndrome would you recommend changing the oil cooler to the better Dorman replacement due to very common failure on these pentastar engines

If anything it’s a great refresher course. We don’t always remember what we’ve learned in the past. You’re always have some great information that we learn from.

When Mr. O. asked Mrs. O. if there were any lovely assistance available, I was hoping she would reply: No, Josh went to lunch.

I don't know about anyone else, but when it comes to diag or what takes away points at the car show, I trust you implicitly.
