Did you instal a "new" computer or a used computer?
Is the check engine light coming on at all?

There is no way of knowing if you even have the right computer installed. If the check engine light is on, then the best place to start is reading the stored codes.
Diagnostic Trouble Codes - 1991
Chrysler
11 Engine has not been cranked since battery was disconnected.
12 Memory Standby power lost.
13 MAP sensor pneumatic circuit.
14 MAP sensor electrical circuit.
15 Vehicle speed/distance sensor.
16 Loss of battery voltage sense.
17 Engine running too cool.
21 Oxygen sensor circuit.
22 Coolant temperature sensor circuit.
23 Throttle body temperature sensor circuit.
24 Throttle position sensor.
25 AIS motor driven circuit.
26 Peak injector current not reached.
27 Fault in injector driver interface circuit.
31 Purge solenoid circuit.
32 On Calif. models, EGR diagnosis.
33 A/C cutout relay circuit.
34 Speed control solenoid driver circuit.
35 Fan control relay circuit.
37 Fault in part throttle unlock solenoid driver circuit.
41 Charging system excess or no field circuit.
42 ASD relay circuit.
43 Fault in ignition coil control circuit.
44 Loss of FJ2 to logic board.
46 Battery voltage too high.
47 Battery voltage too low.
51 Oxygen feedback system stuck at lean position.
52 Oxygen feedback system stuck at rich position.
53 Internal logic module problems.
54 Indicates a fault in the distributor high data rate pickup circuit.
55 Completion of fault code display.
62 Indicates unsuccessful attempt to update EMR mileage.
63 Unsuccessful attempt to write to an EEPROM location by the controller.
77 Speed control power relay circuit.
To call up codes, cycle ignition switch on, off, on, off and on within 5 seconds. Stored codes will be indicated by flashes of the power loss/check engine lamp. The codes will be indicated as two digit numbers, with a four second pause between codes. An example of a code is as follows: - Power Loss/Check Engine Lamp illuminated for approximately 2 to 3 seconds as a bulb check, then turns off.
- Lamp flashes 2 times, pauses, then flashes 6 times.
- Lamp pauses for approximately 4 seconds.
- Lamp flashes 3 times, pauses, then flashes 1 time.
This would indicate that code 26 and 31 are stored. The lamp will continue to flash until all stored codes have been displayed.
Once the lamp starts flashing the stored fault codes, it cannot be stopped. If a code is missed, the entire procedure must be repeated. The lamp will not indicate if oxygen feedback system is switching lean-rich or if idle motor system is operational. The lamp also cannot be used to perform actuation test mode, sensor test mode or engine running test mode.
After all fault codes have been displayed, then power loss/check engine lamp can be used to verify switch function. The lamp will turn on and off as the switch is turned on and off.
