You mean LH2.0 I assume.

Run the pumps with a jumper and give the return line a squeeze. You can do that with LH2.0, can't you? I mean, there's a rubber portion after leaving the regulator? When you squeeze it briefly, you should feel the flow pushing back and hear the pump complain, telling you the regulator has pressurized the rail to its regulation point.

Once you've determined you have fuel distribution, the next question is whether the injectors are getting turned on. LH2.0 (no such animal as 2.1 on a 240 despite ref's to it here and there) needs the rpm signal from the coil to operate the pumps and turn on the injectors. Neither is necessary to run it on starting fluid. If you're wondering about power (like from fuse 13, and the red lead) check it all by seeing the AMM is getting the orange lead hotted up with the key on.





Yes, this is a B230F not a B23F, but the test works the same.

A husband got in big trouble after his wedding anniversary.
His wife told him the day before: "Tomorrow there better be something in the driveway for me that goes zero to 200 in 2 seconds flat."
The next morning the wife found a small package in the driveway.
She opened it and found a brand new bathroom scale.
