With the key turned to posII, the IAC motor should humm or vibrate.

Check for fuel pressure at the end of the injector rail by pushing in on the schrader valve. Keep a shop rag handy in case there is some pressure.

The fuel pump should humm for a second or 2 after turrning the key to posII, if not verify that the fuel pump relay is working.

Check all codes in a-6.
