Hesitant starting when cold after supercharger install (with video)
I'm noticing the car seems to hesitant at starting when sitting for 5+ hours after i had a factory lotus supercharger installed.
It use to crank for a second when holding the Engine On button, then start right up. Now it cranks for about 3-4 on cold starts and sounds really weak before starting up.
Battery is always on a tender. I also notice that if the engine is warmed up and I start the car, it'll crank the usual 1 second and start right up.
Added video here. A little hard to hear, but when it does fire up, the engine sounds weak. You can see the RPM bouncing around the 500 rpm range before it finally gets up to ~1000.
Changes since I started noticing this:
-Supercharger install
-injectors
-spark plugs
-re-tuned ecu (lotus sc)
-drive belts
Things I've checked:
Fuel pump does start up when putting it into On position.
Checked fuse box in engine compartment and used a fuse tester on each
Checked battery - ~13.5 volts
Checked fuse block in engine compartment - ~13v on both
Reset the inertia switch
Checked ground wire to vvl solenoid
