There is no cap and rotor. It is a DIS system. The Distributor Ignition (DI) system consists of the distributor, hall effect switch (camshaft position sensor), ignition coil, secondary wires, spark plugs, knock sensor and the crankshaft position sensor. The system is controlled by the Vehicle Control Module (VCM). The VCM, using information from various engine sensors, controls the spark timing, dwell, and the firing of the ignition coil. It is used on some 4.3L models
If your S10 has a 2.2L engine, it doesn't have a distributor cap.
It is in the very back of the engine. Just follow a plug wire from the spark plug to the distributor cap. It is hard to see. All the plug wires start at the distributor and then hook to each plug.
We need to know which engine it has.
It has a coil pack but no distributor.
HEI? inside the distributor cap
Yes it does it is under the distributor cap.
That should be a 2.2 engine and no, it does not have a distributor cap. It has a DIS (Distributorless Ignition System).
If you have the 2.2 L engine in that 99 S10, there is no distributor in that vehicle. It has a DIS (Distributorless Ignition System).
The ignition module is located in the distributor, under the distributor cap.
Need to know what engine you have.
That would be the distributor.
The ign. control module on a 2.8L s10 is in the distributor. Remove the distributor cap and it is attached to the base of the distributor
