Thanks for the tread on how to remove the seat! The tank look to be about 12’’ tall. 

Use the setup menu on the Maliview screen to check for active or inactive engine faults.

I learned something after the replacement process that made me pleasantly surprised. The MTC 12” replacement screen is polarized! I first noticed that to the naked eye the new screen had a bluish tint to it. The factory screens do not, at least mine do not. I learned from a pilot friend that if you turn your polarized sunglasses (Costa  in my case) 90 degrees to the screen it is like flipping a polarizing switch off and on. You can immediately notice from a distance which of my 2 screens is polarized and which is not. Not a big deal really either way. But I do notice that I can kind of use the new screen as a rear view mirror where I couldn’t on the factory ones.

If the 5-7 second delay is before the starter engages, then try waiting 8 seconds with key in the On position before moving it to Start position.

 However, if the delay is after the starter engages, then consider you may have a tank of low-grade fuel or the spark plugs should be replaced. 

No diacom access but ill be at the slip tomorrow after work tomorrow to check for the shorts and the bad sensors. Ill also check analog FP. 

Update:

Checked FP on rail, getting 62psi.

I verified 5v reference and good ground. (All good)

Checked resistance on all 3 wires. (All good)

Check continuity on pin 2 to ecu harness plug.(All good)

Then I back probed pin two with key on engine off found no voltage. Determined the FP sensor to be shorted/open

I ordered a new FP sensor for malibu parts. 

My diacom unit will be here today as well.
