5.3L with 4l8e: Long crank time
Hey guys, I have been having a long crank time since I swapped this engine in. About 6-8 seconds to crank after driving it around however the first start of the day is always instant.
Not sure what could be causing this as it runs great, only thing I can think of is that the fuel pump is going out as it is at 340k miles.
Just shoot some ideas,
thanks

Buy the $30 fuel pressure gauge from HF.
Check for fuel pressure. Possibly leaking injector after you shut it off, or simply just low fuel pressure.

After some looking, I found the fuel pressure regulator to be faulty. There was fuel in the vacuum line, easy enough to fix and cheap part. Starts perfect now.
Thanks for everyone’s input. 👌
