The ac, fuel pump and ecm relay all have the same part #.
I replaced the ecm and still no start. Removed all the grounds on body and frame and cleaned and still same. Cleaned neg/pos battery terminals and battery post and same. I ohm'd out the neg cable from the ecm ground connector to the neg battery cable connector and the ohm is 33 and 46, sounds way to high for a ground cable. ...? Now the guage cluster does not work an the lights for the cluster do not illuminate. I found no codes in the ecm either.
