Thank you, Joe, for your response. I'm not anywhere close to a car mechanic but here goes. I ended up having to have my truck towed to a local mechanic. When he got in the truck it didn't start for him at first. Then he said he checked the fuel pump, and it was fine, and it was getting fuel. He said he moved the switch from tank to tank (I have dual tanks) and it started. He also said he drove it and it was fine. That's really odd because it's been running rough and seems it has no get up and go and cutting out and missing. So, they told me to come to get it and they didn't charge me. Well, bringing it home it done the same thing, ran rough and it seemed it was going to shut off. It also backfired. Luckly, I got home. We called back the next day to tell them and we asked if he tried to do the OBD1 codes and said no. That's a real bummer because we asked if they could do a Diagnostic and they said they would. We really trusted these guys. I really like to know what's wrong with the truck. I'm afraid I'm going to be stranded one night because of it. Anyway, I looked at the site you gave me and also watched some videos online about the OBD1 but when I went to my truck there's no A and B letters mine have other letters and they are very hard to see but it looks like mine has M and N letters. So can you tell me what Port I should put the wire in? I don't want to just put it in anywhere don't want to burn something up. I put a picture of what I think the OBD1 is. So, please let this 64-year-old lady know any information you can and if this is the right place to put the wire and where if possible. Thank you for all your help, it's so nice to have this site.
