97 intrepid 3.5l start and stall

have changed plugs,wirers,injectors and pcm.it starts runs for 3 seconds and dies. has 150lbs <>15lbs per cylinder compresion.:banghead: lights flash after this happens for 5 minutes.no secuity in this car. black key,secuity i believe has a gray key.

PCM and BCM were to blame for this

This sounds like the vehicles secuity alarm may be disabling the fuel pump . Have you tryed disabling the alarm with the key fob ? Try cycling the key in the drivers door lock clylinder.

count the light flashing there will be spaces kinda like morse code that is giving the code numbers of what it is seeing and then can check manual for the translation. also check fuel pump it may be going out where it has proper pressure to start and then wont hold it after starting.
