I need help! What do I need for replacing my fuse harness?

Oh that I do understand. I do plan on taking it to my mechanic. I just need ideas and if they are wrong that is okay. I can have things ruled out I just need somewhere to start. My husband says if it is an electrical issue I have to get rid of my car. I got this car because it was my grandmother's and I don't want to have to get rid of it

Best guess would be an ignition switch , but just a guess. Vapor-lock is highly unlikely on anything with fuel injection due to the return system on it. I would assess the vehicle condition and also there is no way to put a fair dollar amount on sentiment , but I would try to come up with a reasonable amount to agree on for diagnosis and then go from there maybe an hour diag and $300.00 to fix (parts and labor) get my meaning?

I am taking her in tomorrow. I will have them look at the fuel regulator and see if that is the issue. My machanic is really good with me. I am going to have them run diagnostics on her but because no warning lights are coming on I don't know if that would help. I am trying to get her running the way she did a few weeks ago. Let's hope they can find the problem. Thank you for you're help and when I know anything I will post it :)
