1998 4.2 Where is the location of the computer? Also is it called ECU or PCM? Is there more than 1 computer? Is there one inside cabin and under hood? THe reason I am asking all these questions: I am getting no electric current to fuel pump. I have replaced fuel pump, relay, fuses and followed wire and there are no visible signs of damage. Someone told me it could be computer (PCM/ECU). I did also check the emergency fuel shut off switch and it is pressed in correctly. So I am going to change the computer. Where is it ??? lol I am going nuts
