Thanks in advance for any assistance, and I apologize in advance if I incorrectly posted this.
1994 Seville STS - 4.9 Northstar
Auto trans on floor
Approx. 115,000 miles
Condition: good~excellent, southern car, little or no metal corrosion/dry rot on plastics, appears to have been well maintained, has had body damage in front - repaired and repainted at one point.
Codes: (only 1 code)
P095 - Engine Stall Detected (History)
Starts up smooth as glass, but shuts off approx. 2 seconds later.
Fluttering the gas insanely fast (like your life depends on it) will keep the engine chugging poorly for 20 seconds or so until your leg gets tired. WOT or no throttle at all will both stall. Mid range throttle will also stall, no amount of throttle can seem to keep it running.
It does not appear to be the security system. If I put tape on the key resistor (to cause an open circuit) , I get a "Wait 3 Minutes" message on the dash. I do not get this message when starting normally with the key un-taped.
Misc. Info, I don't know if any of this matters but you never know, in no particular:
I recently purchased this car, it had this problem when I bought it. It sounded like the security system which I speculated was a simple fix, but do not believe it is.
The only prior information is that it died on my buddy in a parking lot at low speeds, and has had the startup/shutdown symptom ever since.
Fuel pump has been changed out twice, to no avail.
I do not yet have an FSM, but will be procuring one very shortly.
I changed out the crankshaft positioning sensors to no avail.
There is no battery in my keyfob remote.
There is no passenger side muffler on the car at the moment
When I open the driver door, the Security indicator lamp is blinking, but turns off when I close the door.
Trunk hold down appears to need replacing also, and the truck is stuck open at the moment. When turning the key forward, the dash states the trunklid is open as well.
