Dodge Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im David, just because they are all getting command from the PCM doesnt mean they are all responding properly even with the resistance reading close to each other. the proper resistances should be around 14.4-14.7 ohms.
here are a couple of prints to familarize yourself with the syatem
the fpr is indeed located in the tank within the intank fuel filter.
whats the voltage at the battery while the engine is running if i may ask?
i need to know the voltage with the engine running at 2500 rpms. then we will worry about a step by step. i dont like to get ahead of myself. if thats not acceptable to you, i will opt out and allow another tech to chime in. thank you.
ok, thats good. we will pick this up tomorrow. its almost 1am here. got to get some sleep.
ok. let me look at the procedure.
Hi there. Different expert here.
Before OBD-II came along, Chrysler used two-digit codes that were not very explicit - in your case, code 27 indicates a problem with the injector control circuit; it doesn't specify which injector or what part of the circuit. Because of its complexity, this type of diagnosis was usually handled only by the top diagnostic technician at the dealer.
The key to this diagnosis lies not only in the technical knowledge (which I can certainly provide), but also in the tools you use; you'll need a DRB-II/DRB-III or equivalent bi-directional scan tool that can actuate each injector individually or, preferably, a scope with a low-amp probe attachment that can show the current being used by each injector - that will allow us to isolate the circuit causing the issue. Do you have access to any of those tools?
I'm sorry, but it looks like I won't be able to help you. I'll opt out so others may try. Please don't rate or reply until another expert responds or the site will cycle this back to me.
