1988 w126 300SEL starting possible fuel issue

[junker68]

Hi,

Can't get my 300 SEL started, here's what I have done so far.
The fuel pump wasn't working so I replaced the fuel pump with an old one laying around.
The car still wasn't starting, so I jumped the relay. Ok, so now the fuel pump works and the car still would not start.
I then removed the main line to the fuel distributor and fuel comes spraying out when the relay is jumped.
I then removed the first fuel injector line closest to the radiator and no fuel reaching the injector with pump running.
Any thoughts on what would be between the fuel distributor line and the injectors that would impede the fuel from reaching the injector.
Am I troubleshooting this wrong, any ideas?
Issues first started today when I went out, turned the car off then and I went to start the car and no go. There were no issues driving to the store. The car then sat for about 15 minutes as I waited for a tow truck and it then started and ran fine and I was able to get home. I turned the car off, waited a few moments and here we are. Car cranks fine, just no start.
There were no issues before the car not starting today.
Thanks, Dwayne
