my dads 90has been sitting for awhile and won't start I replaced the fuel pump and filter attached and it still won't start. Spraying starter fluid into the tb causes it to turn over then die. What am I missing?

 

are you getting fuel to the engine?

 

I would assume no since it starts with the stater fluid and not when just trying to start it normally

 

Have you replaced the fuel filter (by driverside frame rail), or just the fuel sock?

 

Make sure the ENGINE fuse in the interior is good.

If good, then jumper the yellow, two socket connector near the afm/pressure sensor. Then turn the key ON, engine OFF. You should be able to hear the pump run.

If not, there are other things to look at.

 

My dad said he did replace the other filter but he was doing some reading and thinks he might have put it in backwards. Don't they only flow one way?
