    Thanks for posting...one of the first things I did was pull and check all fuses on both busses as well as any fusible links in both the ignition and fuel circuits...all ok. Thought that perhaps the fuel shut-off switch may have been tripped somehow, but this vehicle does not appear to have one.



    Checked fuel pump and coil operation...both OK, as near as could be determined without it actually running. Likewise, rail fuel pressure and sparkplugs checked out ok. Beginning to suspect a timing issue. This weekend will take it apart and inspect the belt...will be a chore, have to basically disassemble the right side of engine.

Bad misfire


run the fault codes as misfire can be from injectors , low fuel pressure and ignition problems
all temp gauges will show a rise on stopping an engine as there is still residual heat in the block and heads with no water circulation and cooling
the fire from the exhaust indicates an exhaust valve is not closing properly so a compression test would be in order to check for valve problems or hydraulic follower problems

SOUND LIKE YOU HAVE A TEMPERATURE PROBLEM, HOOK UP SCANNER AND CHE THE TEMPERATURE ON THE ENGINE, DOES IT GET HOT QUICK, LIKE A CLOSE THERMOSTAT, IS IT LOW ON FLUID, DOES THE TEMPERATURE SENSOR READ OVER 200 WHEN WORM, DO YOU SEE THE TEMPERATURE GO BACK DOWN TO 15 OR LESS, ES TEMPERATURE GOES UP, LESS AND LESS GAS GOES INTO THE ENGINE IS INJECTOR SENS LESS AND LESS FUEL, THE TEMP SHOULD BE 180 TO 210 OVER THIS MEANS THE THERMOSTAT IS CLOSED OR THE WATER PUMP IS NOT CIRCULATING ANY COOLANT, BELOW 180 MEANS THE THERMOSTAT IS ALWAYS OPEN.

You may have a thermostat that is stuck in the open position not allowing the engine tom warm up fast enough to please the computer. Depending on which engine you have, locate the thermostat housing and replace the thermostat.

You could also be a little low on coolant. Take off the radiator cap when the engine is cold and check the level.

2001 Chrysler Town & Country getting 9.6 mpg


yes you need a new thermostat or there is low coolant. this will affect the mpg because your overheating and thats why its stalling. dont drive until you fix or you will blow your head gasket if it isnt blown already. change thermostate and check coolant.

While running the air conditioner the Thermostat goes hot, when I turn the air conditioner off it goes back down. The low coolant light came on but the coolant is full. What else could it be?


To start with, you are talking about the temp gauge. The thermostat is in the engine.
The coolant system could be low or have air pockets and still look full.
First thing I would check is the cooling fan, then the coolant level.

Sounds like the thermostat needs replacing. Doesn't seem to be opening all the way. You can check it by putting it in a pot of hot water and watch to see if it opens all the way.

The engine will not come up to temperture. Replaced the thermostat


You will need to test the engine with a infrared temp gun to see what the temp really is. If its at about 190 to 210 them most likely the sensor is bad
