DISTRIBUTOR? OR SOMETHING ELSE

1992 Plymouth Acclaim

Electrical problem
1992 Plymouth Acclaim 4 cyl Two Wheel Drive Automatic 175000 miles

Hi there I have a 1992 plymouth acclaim with a 2.5L 4.0cyclinder, we have replaced the distributor with an after market and the computer (used) and the coil and wires and cap to the distributor (new) I was told by a friend that there is a module in the original distributor that is not in the after market version that I need for the car to start and the distributor was wiggling so maybe it is the wrong one? Has anyone heard of this, the car won't start, I don't have any spark.

DIRECT IGNITION SYSTEM (DIS)
The crankshaft angle sensor detects slots (4 per cylinder, 20 degrees apart) around an extension of the drive plate. Basic timing is preset by crankshaft sensor position and is not adjustable. By using a crankshaft sensor, spark scatter has been eliminated.
A camshaft angle sensor supplies fuel injection synchronization and cylinder identification information by sensing slots located on camshaft sprocket or camshaft (Monaco and Premier). For sensor location, see the CAMSHAFT ANGLE SENSOR table.
The SBEC fires one coil at a time. This one coil in turn fires 2 spark plugs simultaneously. One cylinder is on compression stroke and the other cylinder is on exhaust stroke. A low primary resistance allows SBEC to fully charge ignition coils for each firing. See Fig. 4.

MAGNETIC IGNITION SYSTEM
2.2L, 2.5L & 2.5L Turbo
A Hall Effect switch is located in distributor assembly. The pick-up supplies RPM, fuel injection synchronization (2.5L Turbo) and ignition timing data to the SBEC. The SBEC determines ignition spark timing and injector pulse width to maintain optimum driveability.
