The engine wants to cut out, shut everything down off and on. I took it to a Chrysler dealer and they got a lot of different codes. They blamed the computer, but could it be a sensor or a faulty ground someplace. Their only solution is to spend $700 for the insulation of a new computer and then they say more fault codes could come up. The van has been driving very wel, l does not use oil, new tires, struts etc. Hate to think of junking it just cause of bad brain? It has a 3.3 engine.

Thank you

Do you have the codes?
When you say every shutdown does that include radio and headlights
or just the engine stalls
if you cycle key on off on off on read P codes in the odometer area
unfortunate if its the PCM that is bad you have to have the dealer flash and reprogram the new PCM
with out that engine will not start
lets get the codes... And let me know
computer will not turn radio off and or the headlights
let me know

It has 8 codes: IGN #1 #2 #3, Primary Cir Injector #1 #3 #4, Control Cir P0201 P0204 P0203 -needs PCM

And NO the lights and radio stay on There is a audible click and engine cuts out. Speedometer goes to zero and back. I can get up to speed, but sometimes engine just turns off. Thanks

A list of check need to be done to determine if its for real the PCM or wiring or injectors

INJECTOR CONTROL CIRCUIT

1. On 3.3L except flex-fuel and 3.8L, ensure ignition is off. Disconnect connector at injector No. 1.
NOTE: Injector No. 1 is first injector back from front (timing chain end) of engine on left side when viewed from flywheel end of engine. This injector is located above cylinder No. 2, but delivers fuel to cylinder No. 1, due to crossflow intake manifold.

2. Using ohmmeter, check resistance between electrical terminals on injector No. 1. If resistance is 10-16 ohms, go to next step. If resistance is not 10-16 ohms, replace injector.

3. Turn ignition on. Using scan tool, actuate Auto Shutdown (ASD) relay. Using voltmeter, check voltage at terminal No. 1 (Dark Green/Orange wire) on connector for injector No. 1.
4. If voltage cycles from high voltage to low voltage, go to next step. If voltage does not cycle from high voltage to low voltage, repair open circuit in Dark Green/Orange wire from ASD relay to injector No. 1. The ASD relay is located in power distribution center at driver's side front corner of engine compartment, near battery.
5. Turn ignition off. Disconnect connectors from Powertrain Control Module (PCM). The PCM is located between driver's side front fender and power distribution center, near battery.

6. Using ohmmeter, check resistance between ground and PCM connector terminal No. 13 (White/Dark Blue wire). If resistance is 5 ohms or more, go to next step. If resistance is less than 5 ohms, repair short to ground in White/Dark Blue wire between PCM and injector No. 1.

7. Using ohmmeter, check resistance between terminal No. 2 (White/Dark Blue wire) on connector for injector No. 1 and PCM connector terminal No. 13 (White/Dark Blue wire). If resistance is 5 ohms or more, repair open circuit in White/Dark Blue wire between PCM and injector No. 1
If resistance is less than 5 ohms, replace PCM
