what is the fuel pressure supposed to be on a 1994 honda accord lx 2.2 4cyl?

Go to autozone.com and register. Fill in your info (Year, Make, Model, and Engine) into the vehicle profile. Click "repair info", "view repair guides", "Driveablity & Emission Controls" then "Troubleshooting Charts".

You should be able to find it in there. I would look it up for you, but there are 390 charts (I kid you not), and I'm on a dial-up connection at the moment, and it would take me all day. Maybe two days. LOL

You want the charts for PGM-FI, 1994-1995 Accord. They start with fig. 195, about halfway down the page.
