When hot will randomly not start unless gas pedal is pressed all the way down. on a 2001 honda crv. replaced fule pump,fuel relay,fuel filter, dist. cap, rotor, coil,plugs, wires, and ignition control

If you hold the pedal to the floor it puts the fuel system into Clear Flood Mode. This prevents the injectors from firing and lets the already present fuel burn out. Now if this has to be done on every short trip you probably have a leaking injector.

Does the vehicle seem to crank slowly or stop and then crank when this happens?

When you push the gas pedal all the way to the floor, is the engine revving up? Does the transmission engage at all? Have you checked the transmission fluid level? Is it foamy? Do you smell something burning or burnt?

Sluggish when pressing gas pedal

My guess is a compression problem - which could be caused by something simple and cheap to fix or as serious as a new head gasket.

I get a lot of hesitation when i press the gas pedal. I smell antifreeze on the driver's side of the truck. this is a 2000 lincoln navigator. the floor is wet with antifreeze or something. what could this...

if you use the orange antifreeze than id say you have a blown intake gasket or head gasket, combustion gases in your antifreeze makes it very acidic which probably ate a hole in your heater core and will probably eat your radiator soon if not fixed
