I just got my hands on an 89 Nissan PU with the 2.4L 4cyl.
When starting cold it will tourn over then abruptly stop...groan slowly....and turn over again a few more times.....groan slowly....turn over again a few more times till it fires up.
Is this a compression issue? Its almost as if the motor is locked up.
Once it starts it runs fine. And starts back up again very easily after its warmed up.
The issue only happens when the engine is cold.
