Welcome to FTE, John.

The first place to start is with the batteries. Are they putting the right amount of volts? Are the connections clean and tight? Use a meter to test the cranking volts while cranking. The PCM needs to see about 10.5 volts while cranking for the IDM to tell the injectors to fire.

Is it more difficult to start the longer it sits? If so check the oil level in the HPOP reservoir after it sits for a few hours. If the HPOP reservoir is draining down it takes longer cranking time to start.

Here's where to check the HPOP reservoir level. The plug is a 3/16" allen.
