Do what I said in first reply if you don't scan for codes you may not know at all where to start aconverter won't do that. What is your fuel pressure exactly? If it's not 35-45 psi then it'snot ok

The the fuel pressure is 30PSI and when I unplug the vacuum hose it raises up to 40PSI and when I plug the hose back to it it goes back to 30 is more like 29 PSI than 30 so what can I do next should I change the fuel pressure regulater
