My 1998 Ford Mustang with a 3.8 v6 wants to start very hard when the engine is either hot or cold but mostly when its cold. I've replaced the fuel pressure regulator thinking it had something to do with it but it still starts hard. The fuel pump, injectors, and filter are all good but i just don't know what it could be.

it's your upper intake manifold gasket. it has a crack in it and needs to be replaced. your getting to much air and not enough gas. mine did the same thing.

Make sure the radiator pressure cap is the correct one and that the hose is not soft--check the lower hose and heater hoses for softness as well. They should be firm, but not hard or cracking. The temperature sensor is reporting normal operating temperature, so it and the thermostat are working correctly (hot water would blow out of the radiator if it were stuck). Check the cooling fan for free turning and no noise. Check it's grounding connection. Check the fuse box for blown fuses to the fan and to the A/C compressor. Make sure all the relays and fuses are firmly pressed into their sockets. Check the A/C compressor clutch winding for resistance--should not read infinity. Does the blower motor for the heater/A/C run when either is turned on? The A/C switch on the dash may be defective.

If you are talking about the axle hub nuts,then you may have to use an air impact socket driver and impact sockets.These nuts can be torqued to over 140 FT LBS. Let me know if you need more help.MOE
