Starting issue after new battery.

[xxShaneOmac]

Car would die every 4 days of not being driven, took out my battery and Autozone told me it would not hold a charge so I purchased a new one and put it in the car.

Grabbed my laptop and turned the key to on, loaded my ECU file for DSMLink 2.0 and started the car. It instantly goes to 14.7 AFR and idles at 1k perfect for 2-3 minutes.

The next time I looked at my AFR it was 11.0 and holding solid while at idle and 0 throttle. I had in the meantime adjusted some settings in DSMLink but none of them were to do with fuel. I tried to give it some revs to see if it would come of it and then drove it for a second. After 10 seconds of driving it died on me. Started again and it was a strong start and put it in gear and drove off and once I let off the throttle it died again. 3 more starts to get it back into my driveway each time it dieing sooner and faster than the last when I was not giving it gas.

Trying to start it now and it will never catch unless I feed it gas and it dies the second I let off the gas.

Looked over my DSMLink and all settings are correct, -46% global 330 deatime (tried 420 as well) My Invert Cas is not grey'ed out (tried it with it greyed out, not sure what way is right for a 99eclipse with a 95eprom) nothing worked. Checked my AFPR and its at 43.5 w/o vacuum like it should be.

I smell a good amount of gas around the car and with what my AFR was saying it was rich. I assume my stock o2 sensor is going out and its messing up the readings and my car is not getting air at all.

Any other ideas or ways to prove that? Also, could someone let me know if I should have Invert CAS grey'ed out or not on the link?

Thanks

Near 90 views and no comments, Im not sure if DSMTuners is dead compared to the last time I was here or if My issue does not have enough detail.

I will expand a little.
When starting the car it starts almost instantly like it normally would but was the RPM's are climbing they die almost instantly once I release the key from cranking it over.

So it starts, it just dies as fast as it starts and does not hold an idle, unless I hold the gas down. While holding the throttle 50% or so the car will hold 2-3k rpms or more if I floor it but its rough and jumpy and the second I let off of the throttle the car dies.

I just replaced the battery and negative terminal. Outside of that I have done very little, just cleaning the bay etc.

These are things I have found while searching.

Coolant sensor
o2 sensor
ICV(?) Sensor for idle control

Hope this helps some with maybe a few ideas or tests I could go with.

So I have been trying more and more to see whats up.

I pulled the spark plugs and they smell of fuel so I know I am getting that. They are slightly black but nothing abnormal.

I continued to try and start it today and did not get very far. I thought maybe my timing jumped so I pulled the top timing cover and continued to barely crank the car so I can see all the teeth. Where Im not 100% sure that I saw every single one there was nothing that stood out on the teeth.

2 things did stand out. I never saw the timing marks line up, and where as I didnt have a wrench on the pully turning it slowly, it was a fast engine jerk the marks never lined up thinking maybe the belt jumped a few teeth and things are not inline. The belt was tight though.

Another thing was that there was scratch marks in the belt like something had been rubbing on it. It was not very deep but it was noticeable.

I uploaded some pictures here Photo Album - Imgur .

Let me know if anyone has any more ideas.

Post a log. Also have you looked at ECM tuning?
11 Afr at idle is really rich you may be fouling the plugs with gas.
I would also make sure you do not have any bad connections or corrosion.

Cannot log much the car cannot stay running.

After 20 attempts to start the car will start once and limp for 5 seconds then dies.

Maybe coolant temp sensor or ECT?

Go into link with the key on and log what all the sensors are saying with the car not running
