i'm not sure what the problem is, but you would get more of a response if you posted in the hybrid section or even engine management. that buzzing is more than likely your main relay, or fuel pump maybe.

what you have is an 86-87 PG7 (brown top d16)... not compatible with 88+ cars because it runs off vacume advance. You need an 88-89 PG7 (Black top d16)... do yourself a favor and stick with the pm6 over the pg7. PM7 is the "ZC" and is the ecu you need.

you also may want to check the FOR SALE section, some1 had a PM7 for sale. or you can post a WTB in the wanted section for a PM7.
