i needi have an 87 4 +cylender 2.5 Chevy s10 pickup and need the timing diagram in order to get it running. can you help?
The ECM does. The module is only a pickup and a signal conditioner. There is a tan wire with a black stripe that disables timing advance when disconnected, so maybe that's whats going on. Its near the realay center on the firewall.
does not have a timing belt it has a chain
There is no timing ajustment, Its controled by ECM- Computer.
You don't. The timing is adjusted thru the ECM.
Yes, but that would eliminate about half of your advance curve, which you need.
Counter clockwise to advance.......clockwise to retard
