Check the solenoid. If thats good then go back over the wiring and make sure its correct. There is wiring diagrams floating all over this site with the digram so it shouldnt be to hard to find.

Does the CEL work [turns on for 2 seconds when key turned to ON(II)]?

What ECU do you have?

Is the filter in the solenoid clogged?

Is the oil pressure low?

If the solenoid is not leaking oil, then the gasket should be fine. Just make sure the filter is not clogged. Also do the tests in the diagram.

Borrow a multimeter. Or buy a new digital multimeter ($15-$20). You'll need this anyway to test the wiring.

A basic digital multimeter is not very expensive. Call around to Walmart, Sears, Harbor Freight, etc. for the best price. You must have this basic tool to work on your car. Good investment.
