I got a PM from a member who needed help getting something posted. So here's what he sent to me:

2003 R1150GS will not crank and run. New fuel pump, new fuel filter, new injectors, new coil. Good spark, good spray pattern on cardboard test for both injectors.
Please, does anyone have any idea what would be causing this? Was running good till fuel pump died?

Fuel lines?

Did the in line get switched with the out line? Make sure the high idle cables are properly seated especially the right side. Go back and check all the work you did and all the places you visited on the bike. Lastly did the the old fuel pump quite working or did the bike die due to something else and someone assumed it was the fuel pump?
 
I'm missing something: "will not crank and run".

If it doesn't crank, wouldn't that be the place to start?
 
The fuel lines are correct , won't go but one way they are male and female. Did not touch the throttle cables, there's only one on each throttle body and they come to rest on the adjustable stop screw. they both together when working the throttle. Not familiar with a high idle cable? I was very careful and didn't touch any other part enough to keep it from performing. I'm 81 yrs old and don't much anymore the bike's been sitting uo I usually crank it once a month and let warm up to normal temp. I knew the fuel pump was out turned the key on and it didn't run up to pressure. So I replaced the pump and removed all the old gas, cleaned everything best I could installed new fuel filter flushed fuel lines with new gas from tank to where they connect to injectors. Starter is working good sure don't want to burn it up trying to crank. After it sits awhile it'll usually fire when if first turns over, then the starter just grinds. Nothing. Darndest thing I've ever had happened working on a bike?
Thanks for your reply.
