I have a 1995 Chrysler Concorde. Its an old new vehicle meaning it is 20 years old in age but basically new in use and in excellent condition. It is fully optioned with the 3.3 V6, 42LE electronic 4 speed transaxle. The car sets for long periods of time. Of late, outside in the hot Texas sun. The problem is this. It has set since early spring and when attempting to start, the engine
will start but stops immediately. I have been through the entire fuel, engine electrical, emissions and engine control systems. I have a specific Chrysler maintenance manual for the vehicle and have applied it cover to cover. Fuel pressure and system components, fire to coil, injectors (using NOID light), spark to plugs, all sensors check OK, the PCM, air filter
, vacuum hoses and electrical connectors all function as specified. I have yet to check the EGR valve, for vacuum leaks in the plenum and intake, or the injectors themselves (possibly stuck from the methanol fuel drying in them). This is not a flex fuel vehicle. I grew up in the sixties during the muscle car era and had my share of go-fasters. I raced Pontiacs, Chevy's, and big cube Mopars for fifteen years in 1/4 mile dirt track and NHRA drag competition until it got to expensive and commercial. The fun was gone. At one time a friend and I had a '66 Charger with a 426 c.i. hemi/4 speed (our tow car), a '65 Cornet 500 with a hemi/727 torqueflight (drag car), a '68 Cornet R/T with a 440 six pack/4 speed square gear (a Grand Spaulding Dodge, 650 HP, factory race car/D Super Stock), and finally an "A Fuel" slingshot dragster with a 426 c.i. Max-Wedge coupled to a worked 727 torqueflight direct-coupled to a 80 series Dana Splicer tall-gear turning 14" M&H wrinkles. These four vehicles were our "stable" run under the "High and Mighty" banner. We followed Dick Landey, Sox and Martin, Ed Pink and other big name Mopar racers closely. All this to say this little V6 Concorde is kicking my back side. In frustration I went to my local Chrysler dealer and spoke with the service manager and his mechanics for their input. The service manager contends the problem is not in the engine but a security-theft circuit problem. He spoke of the door lock reset anti-theft circuits and I found the one in the passenger-side door to be broken. I purchased a Mopar(###) ###-####security alarm switch off E-bay and am waiting for it to arrive. However, in surfing around I came across your site and thought to run it past you. Any help will be appreciated. I'm stumped. Thank you! If you would prefer my email is (*****@******.***). If it works , I will respond. Thanks again!
