Dodge Repair Questions? Ask a Mechanic for Answers ASAP
I just got back from doing some tests on the car. I checked the injectors with my stethiscope and there's no clicking sound. I sprayed starting fluid in the intake and the engine runs fine until the starter fluid runs out. Clearly the injectors are not operating. I also looked for a fuse for the injectors and the closest fuse I could find was for the ignition. I traced the wires from the injectors back to the ECU. Should I just replace the ECU?
If it has pwer, but doesnt click, and you have swapped the relay with a known good relay, then its either a bad ecm, a bad trigger wire from the ecm, or you have lost power or ground to the ecm,Tim
I removed the cam angle sensor and compared resistance with a new one and the readings were very different, so I went ahead and changed the part. Well, now the injectors are working!
I also had my fuel pressure tester hooked up and now it reads 0 lbs. I can hear the fuel pump come on and it sounds normal. I can't see a fuel pressure regulator on the fuel rail. There is only one line going to the fuel rail . . . no return line.
1). Does this car have the regulator at the fuel pump?
2). If so, is that regular part of the fuel pump (do I need to change the whole thing)?
3). Do I have to drop the fuel tank in order to change the pump?
I changed the fuel pump and . . . bam! Car starts and runs fine.
I thank you for you expert help. I will definitely put in a good word.
