03 town and country 3.3 v6 no sentry key with double start override
No Crank No Start - Everything else works. ECM not Comunicating with Scanner all other modules yes. Black Head plastic key.
PCM Is Good. ( I put it in a dodge caravan and it started right away no programing needed)
All Powers to PCM are Present;C1-20run/start, C1-38startonly, C2-46
All Grounds to PCM are Present; C1-10, C2-43, C2-50
No ground from PCM-C1-31 to Starter Relay 85 with relay unplug; meaning not cranking.(starter is good)
No Ground from PCM-C2-67 to ASD Relay 85 with relay unplug.
No 8 reference volts from PCM-C2-44 to Crank position sensor or Cam position sensor. Checked at PCM Conector and sensors plug; meaning no return signal to PCM-C1-32(CKP) and C1-33(CMP)
No 5 reference volts from PCM-C2-61 to TPS, MAP, A/C pre. sensor.
Checked at PCM Conector and sensors plug. Meaning no return signal to PCM.
Yes Ground From PCM-C2-43 to all sensors as wired.
Some times the Squares at the instrument cluster gear selector all light up and TCM with scanner does not show what gear PRNDL is selected and not reverse lights work. Sometimes it works, just lights up the one selected and scanner reads right PRNDL selected, and reverse lights work. P/N switch signal grounded when parked or neutral.
My reasoning is: something is not allowing the PCM to start vehicle.
What could that be? if not equipped with SKIM, only keyless entry, witch works but does not arms up, or goes off when locked and open door from inside.
Ignition Switch wiring
2. VT/BR ( how is this tested?)
3. 2 CABLES, PK/WT 12VT crank/run. Good
4. Yellow 12vt out on crank only. Good
5. 12vt from battery
After 2 weeks - you are my last hope, and will be greatly appre$$iacted.
