Starting Issues...

[letsjam]

I have a 1990 TGP that when you let it sit overnight it wont start, if you spray a bit of ether in the intake it fires off until the ether is gone, then if you start it, it will eventually start. once you get it started you can stop and start it all you want as long as you don't let it sit for hours.  I checked fuel pump and lines all good. Checked fuel pressure at motor and all good. Wondering if anyone has any insight on this issue?

Thanks

Maybe after sitting for long periods there is no fuel in the lines and it takes a bit to get primed. Leaking injectors and/or faulty pump would be my first thoughts..
