It sounds like the engine control relay is not working. Here are the wiring diagrams to show you how it powers the system on the location of the relay so you can change it out. Check out the images (below). Please let us know what happens.

Thank you very much. I just went ahead and put a new ECU relay in because that’s what I was thinking it was also, but I wasn’t 100% for sure because I didn’t have a wiring diagram, so I wasn’t sure how to check it. but when you said you thought it might be the relay, I just got one and replaced it and it fixed it so thank you very much. I worked on vehicles professionally all my life I just don’t have anywhere to get information from anymore and I will send you a donation.
