starter delay?

I have a 2003 V-8 4wd and notice a delay when starting the engine. Seems like engine doesn't start until I back off on the key. Thought there might be a new design feature that keeps you from eating up starter gears or flywheel. Anyone else have this experience or am I losing it....

They all do it. Many threads and theories on it. Main one is that it pressurises the fuel system and lube pump before starting engine..

tundradad-thanks for your reply, hadn't noticed the thread on it, good for us new owners to know-it's not my imagination......

What lube pump are you referring to?

Engine lubrucation pump aka: oil pump, building up oil psi a little before engine fires..

Thanks. I thought you might have something I don't have and want. What you say makes perfect sense.

I noticed in the control schematic that the fuel pump is energized when we turn the key to the "Start" position. That's why it takes a bit of cranking to start the engine. It takes a second or two for the fuel pressure to rise enough to allow starting. My last truck was a Ranger. The pump was activated when the key was in the "On" position making for an instantaneous start.

This cranking business bothered me too because it reminds me of an engine that needs a tuneup...especially new ignition points in the distributor or an adjustment of the dwell angle.

so-is there something in the design that requires activation of both the oil and fuel pumps before the engine is triggered to start? A need to back off on the key when the pressures build up to an acceptable level to prevent damage to the engine by delaying start until oil and fuel pressure is up?

Thanks for everyone's help!!
