Starts like ass, sputters and runs rich

TsiEagleTalon92 · 10-19-2008

I have had my Eclipse GS N/A sitting for over a year and a half and finally got it running again. It takes a few too many cranks to get it started, but when it does run it sputters while driving and when I get close to 4000rpms then it really sputters and sometimes cant make it over that. When it is cold you are not able to get it over 4000.

My thought is that my fuel pressure regulator is bad and is either not letting fuel return to the tank and is getting shot through the injectors in turn making it run rich and starting like crap.

Any thoughts as to what might be the problem?

did you put fresh gas in it?

**Kracka** · 10-19-2008

Fresh spark plugs and wires?

Fresh fuel with sea foam, iso heat.
New plugs, wires, Recharged filter. fuel filter was replaced before it broke.

Timing/timing belt correct?

TsiEagleTalon92 · 10-19-2008

yup everything is in order the timing belt has about 20000 on it if that.

I think my MPI relay is bad, my pump doesn't receive power so I have it hardwired like my talon and that thing starts just fine.

before I started doing any real work on the car it started just fine but when I dug into all the things I needed to do to it it just stopped starting correctly.

O2 Sensor?

TsiEagleTalon92 · 10-19-2008

swapped it with another spare I have with no change so I swapped back.

Compression Test

TsiEagleTalon92 · 10-19-2008

if it comes down to it I will do that but I don't believe that will be the source.

coil pack? Or maybe when you put the fresh gas in you loosend up some sludge and clogged your Fuel injectors?

TsiEagleTalon92 · 10-19-2008

coil pack was replaced about a year before it sat. I had one other person say I may have clogged injectors. What is the possibility of a clogged filter or a bad FPR?

That gave me a good chuckle. doesn't always have to be an ex for some. (poor guys)

Well filter is probably more likely than your injectors as it would of caught it all first I guess. But FPR.... eh... I wouldnt think you would have these issues. It sounds like a lack of fuel or spark versus running pig rich. Just IMO. Im just thinking with it sitting for a year or so, unless you drained the tank before it sat the gas easily varnished and you may have just broke all that up with your mix of good gas, sea foam, and ISO Heat.

Well it a for sure running very rich. You can smell it a ton in the exhaust and all four of my plugs are already covered in soot. I have a buddy with a 91 turbo that let his sit for a while like a few months and had that but it cleared up in 3 days.

COIL PACK!!! i would replace it but dont get a msd one.

TsiEagleTalon92 · 10-20-2008

Nothing is going in this stock car except stock parts for sure. That would sure suck if its a second bad coil pack... That just doesn't seem right.

TsiEagleTalon92 · 10-20-2008

switched out coil pack with the talon's with no change. I am going towards FPR or bad fuel. A guy at work told me to take off the vacuum hose to the FPR and see if fuel comes out but he did not tell me what that would indicate.

In my eyes I believe I am seeing too much fuel for the car to bear.
