When I tap on the main relay it starts . Bad main relay , right ?

That's very possible. Verify, however, that the CEL consistently comes on for 2 seconds and then goes out, when the ignition switch is turned to ON (Position II).

Never mind , check engine light . I'll verify . Thanks

Yes, it does come on for maybe 2 seconds then goes out when engine starts .

Then, replacing the main relay should solve the problem.

My friend you are wonderful , thanks for your assistance .
