Here's the background: engine was getting harder to start in the morning until it quit starting altogether : took the injectors off got them pop tested: low pressure and 1,4, 5 irregular spray. So I got new injectors, some Bosch 40+. Also put in a new lift pump since fuel was not delivering to the injection pump.
Truck now starts great when cold, but if I run it for a while I've noticed 2 things: one is that it gets a little hotter than before and I assume that's due to the different injectors (?). Second is that if I have to start it when hot, it takes 1.5 to 2 seconds of cranking whereas it starts on a fraction of a second when cold...
Any thoughts?
