How do I check the fuel pressure on my 2007 PT Cruiser ?
remove the plastic hard line that supplies the fuel rail from either end. The end near the firewall is easiest but i remove both to check pressure at each end . It requires an inline connection with your fuel gauge to connect but is only way to check fuel pressure without crawling underneath which would require the same connection. Hope this is helpful. They stopped using the schraeder valve to test in late 03' or 04'.
