Should I crack the fuel line when cranking after reinstalling engine before start up?

Maybe the one supplies the fuel rail? I just did a small rehab on my 3.2L and am almost ready to start it again. Thanks.

What is your reason?

[jibmaster1]

I just wanted to be sure as it's my first drop and reinstall of this car/motor. I'm more in love now then before lol!

There is not a need to crack the fuel line unless you have something very specific in mind.

Check for indication of oil pressure during cranking
Check for leaks
Fire it up and see oil pressure jump immediately

The 3.2L engine is an easier one to start up. You get the timing right it fires. You get it wrong, it does not. No middle ground.

I never do - but you may want to jumper the fuel pump fuse to run the fuel pump for a few seconds to prime the system and minimize cranking while waiting for fuel pressure. This is what I do...

Just start it. Any air will just go out the injectors or the pressure regulator's return line.

I'm in the same boat as I hope to fire up the motor soon after my first engine drop. Could you not just cycle the key on and off a couple of times to prime the fuel system instead of jumpering the fuel pump relay? I also replaced the fuel filter, so I imagine it make take it a little while to prime the system.

You guys were ALL right! Fired up within 5 seconds and purred perfectly! Just like it left the factory 29 years ago
