Put a fuel pump gage on and check for 24-28 lbs, and leave gage on all day to see if you losing presure - If a slow drop in presure then it may start or not till the presure is up

Look to see if you have a crank sensor it may be bad. Its should be sitting above the crank shaft pully. Just a suggestion.
