mikestewart395 Posted March 27, 2014 Share Posted March 27, 2014 I ran the diagnostic, I got code 51 , injector circuit. Makes sense as it is hard starting sometimes. Anyone know more info on this code and what I need to do to begin fixing this issue? Link to comment Share on other sites More sharing options...
Precise1 Posted March 27, 2014 Share Posted March 27, 2014 That comes down to harness connector or injector. I'd start by checking the passenger side wher it is easy, you have a 50% chance of getting lucky. Check the wiring harness visually for any possible damage, check each injector connector for corrosion/integrity and check the pins on the injector with a multimeter for resistance, It should be 10-14 ohms. Check out Diagnostic procedure #35 on page 108 of the FSM, EC-108. It has all the harness test specs as well. B 1 Link to comment Share on other sites More sharing options...
mikestewart395 Posted March 27, 2014 Author Share Posted March 27, 2014 Thanks. Will check that in the morning. Link to comment Share on other sites More sharing options...
mikestewart395 Posted March 27, 2014 Author Share Posted March 27, 2014 I was just thinking, it may be a loose connection. As I said before, it hard starts sometimes, other times it will fire right up. Road and engine vibration could be shaking something loose. Link to comment Share on other sites More sharing options...
peejay Posted April 1, 2014 Share Posted April 1, 2014 I'll add, when testing the injectors for resistance, make sure the terminals on the injectors are good and clean before you rule them out as faulty!!! I "had to" replace two injectors, well, once I had them out, and scraped the terminals with a flat screwdriver, magically they showed the proper resistance!

microfiz Posted July 8, 2014 Share Posted July 8, 2014 Did you ever find out the problem? I have the same issue. Link to comment Share on other sites More sharing options...
mikestewart395 Posted July 9, 2014 Author Share Posted July 9, 2014 The day after I replaced the injector I took it to work, it went into limp mode on the first stretch. At lunch I drove it and I let it rev up tp 5k rpm. I am thinking the ECM needed a restart or something. Then I ran out of gas, lol. Now it is still sitting in timeout, I should be done repairing the fuel sending unit tonight. Thank you JB Weld!!!!! That stuff is awesome. But after I got it back to work I took it in the woods and turned it loose and it was running good. Not confirmed 100% yet, but it was doing good at the time.

microfiz Posted July 20, 2014 Share Posted July 20, 2014 Mine worked too. I followed instructions on how to diagnose the 6 injectors through the harness and isolated injector # 4. She's all good now. Link to comment Share on other sites More sharing options...
