I have a 2006 Toyota Isis and it had a problem where it idled well, but when you press gas the engine started to stall and when you lift your feet then it idled well again. I took it to have it scanned and they said to replace the fuel regulator sensor. I replaced the fuel regulator sensor, but after I put things back together, it just cranks but won't start.

I measured voltage at fuel pump and there was no power at fuel pump. So I looked for the fuse and relay but couldn’t find it. Where's the fuel pump fuse on my '06 Isis?

    Welcome to Motor Vehicle Maintenance & Repair! I cannot find an image for it, but the fuel pump fuse is usually located in the underhood fuse panel. Again, I've got no reference for this, but it's where it's at in most cars. As far as the fuel regulator sensor, try and put the old one back and see if it makes any difference for it starting. See if you can get back to jump street. It may be the new sensor which is causing the issue. – Pᴀᴜʟsᴛᴇʀ2 Aug 24 '18 at 10:10
