Car cranks but will not start.
I will go down the list of what is wrong and what was checked in order.
First off, it is a 1995 3.3l intrepid.
Day one, I start the car up to move it oh, about five feet, and don't attempt to start it again until later that night. That night, I get in to start it and it starts up but it dies on me two seconds later. I keep attempting to get it running and it just keeps on quitting on me. There was no hesitation while cranking as if the battery might be dying, so I know I've got juice. As it was running though the rpms kept dropping too low before it would stall, and I wondered if it was due to voltage. Eventually I said screw it being as it was christmas night. ('tis the season fa la la some crap...)
Day two, I get home from work and decide to try and figure out what the fig is wrong. I get it to start as it was doing the night before, and to no surprise it kept dying. I happened to keep it running by laying on the throttle to about 2000 rpm, and it would surge and drop briefly then go back around 2000. I thought maybe throttle position sensor, but that would set a code and I did the key check for codes and nothing for that came up. Then I went to try and see if it was a fuel pressure problem. The night before I took a pen to the fuel rail pressure port and a good amount of fuel came out, seeing as I couldn't find my adapter for my fuel pressure gauge, but then today I checked it with the gauge and after hooking it on the car wouldn't start after that, at all. That made me wonder if by relieving the pressure it then didn't have enough to start it up again. After that though I decided to check for spark from the ignition coil pack, and I checked it at the pack at cylinders 2 and 6 and there was none, which I am pretty sure there should be spark while cranking even if it won't run.
All in all it has been interesting trying to pinpoint exactly what would make it do these chain of events; fuel pump, ignition coil, fuel pressure regulator, wiring harness for the fuel injectors, or could it even be the PCM? Anyone with some similar experiences or advice?
And two things I forgot to mention; while it was running and the rpms were dropping, each time it did that the lights would dim. And my EVAP purge solenoid was making this ticking sound for a couple of weeks, although I doubt a failed purge solenoid would make it have these symptoms.
I have the next three days off to figure this out, so I am up for troubleshooting through any length of lists to diagnose the problem.
Thanks for your time and for any ideas on the matter.
