1.8 only has supply. Only Injection has fuel return
you might need to look into the hole where pump fits as it has a cam that drives the fuel pump, make sure that has not ground to nothing. Failing that, you can remove just the top cam box cover on the 1.8 to see the camshaft, this will let you see the fuel pump running on the camshaft lobe when turning engine over (don't start the car though, just remove the coil HT lead to no spark or something) as it dies flick oil about if it's runs high rpm. Keep fingers out the box when turning engine over !!
