[V8] V8 not starting - More

 ....  And the reason that you need the TPS, is for proper (any) function of the Idle Stabilizer (N71).  It kicks in based on rpm (~1000) and the (closed) signal from the idle switch.  If you are missing the idle switch signal, the ecu doesn't know to activate the Idle Stabilizer Valve.

 That is a symptom of a bad TPS Idle switch. You can ck the TPS with a multimeter, on the PT engine, the plug should have a BN/BK (Ground), G/V (Idle Signal) and BK/W (WOT Signal).  The Green Violet goes to pin 52 on the ECU (idle switch).  Remove the plug, ck for continuity on the TPS to the pins that connect to Brown/Black and Green Violet.  You should be at 3ohms or less.  If 6 or more, replace TPS.  If ok, ck continuity to pin 52 at the ECU and Green Violet on the Plug.

Thanks for ur help. I ll try to tell the exact story. While driving in 





residential area, I slowed down at a bend when first time the car stalled and 





when i reached home and engine was idling it stalled and stopped. Now I crank 





the engine it starts after very long ignition but when i remove my foot from gas 











pedal it stops immediately.
