2007 Ford Five Hundred will no longer start.
So hear goes. any suggestions welcomed.
car started misfiring the other week. by the time I got home, it threw a code. My reader and autozone reader said it was a misfire in cyl #2. best course, replace the plug and coil on cyl #2... I opted to replace all the plugs. For the record, cyl #2 is the rear center. (v6 FWD) It is kind of a pain to get to that plug so I wanted to replace them all just to be safe. After fighting with it the EGR valve for a long time, i was finally able to get the intake manifold off and swap the plugs and replace the coil. Reassembled everything and fired it up... now have mult- cyl misfire. Figured I must have gapped them wrong or something. Started the disassembly again and noticed a couple vacuum lines i missed. Completed the disassembly and checked the plugs were gapped properly and reassembled.. apparently cracked a vacuum line. replaced said vacuum line and hooked everything up. Still ran poorly. online searched had suggested the EGR itself may be bad... this sucked because the EGR assembly was a pain in the *** to remove. went and bought another tool... replaced EGR valve. Started it up and it Seemed to be running ok... quick test drive... got stranded at the rec center. pulled it home and found that the tube for EGR had cracked... shelved it for the night. Called around to all the local parts stores... EGR tube is dealer only and cost around $70.. no thanks. Jalopy had the piece so I snagged it, brought it home and hooked it up... ran like crap. Front plugs keep getting fouled and are visibly wet upon remove, rear plugs look great ( yes i disassembled the damn thing again). Checked the codes again and it said O2 sensor failure.. replaced the O2 sensor that was specified.. still runs like crap. funny thing, i can remove all three front plugs and the damn thing will start just fine.. just to be on the safe side, swapped plugs with a different set and made sure they were gapped and the coils were firing. hooked it all back up... still runs like crap, if and when it eventually starts.
At this point, it will no longer start...
I've searched quite a bit but have not found exactly what I am looking for just yet. Maybe someone can point me in the right direction.
I've been using the FORScan software just for a short time, previously used other software that was more simple as my needs were simple.
My question, the software is great at getting into the system and showing me the various sensors and values but where can I find out what "normal" is? Some of the PID's do list an "expect" value but not all of them. I've read through other forums and other sites but have yet to find an answer that is specific. Thinking a chart would be useful to show the expected value's that I can then compare with what my vehicle data is displaying.
My car is not currently giving me a code but it also will not start, need to dive into the data and see where a possible failure could lie.
Below is a partial entry of the scan software while attempting to start the car.
