Need to know what year and what engine to help you.
The ignition module is located in the distributor, under the distributor cap.
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.
Gonna need to know which engine you have in there.
It has a coil pack but no distributor.
We need to know which engine it has.
Distributor cap, rotor, plug wires or spark plugs could do that. Time for a tune up.
Yes it does it is under the distributor cap.
HEI? inside the distributor cap
No, the last year that GM used points in their distributor was in 1972.
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).
