Why is my 96 crown vic hot and slow?

If it 'cranks', it is turning over. It is cranking but not firing or running. It does sound like you ran out of gas. The fuel pump is lubricated and cooled by the gasoline in the tank. You need a fuel pressure gauge and check it is still working efficiently. Also remove the fuel hose at the injectors and make sure all the air is out.

The wires on the starter will get hot with extended cranking as they normally only run for a few seconds.

heater core has a small leak..i had the same problem with a Taurus I once owned

I would say your exhaust converter is worn out & blocking
the exhaust from getting out & since you continued to wonder ,
verses actually having the car tested,that you now have ruined the transmission

i had this problem with my 1999 jeep grand cherokee laredo with the brake lights it kept popping fuses right after the ignition was turned on try putting a higher amp fuse in place of the old one that keeps blowing then check for shorts to the starter and check grounds and wires and also the transmission issue check the fluid and then if the fluid is fine change the transmission filter the filter may have not gotten replaced when the transmission was rebuilt and may be clogged or dirty

I have a !996 C.V. with Police Package and it is a blown fuse in the 5 slot found under the dash........I had this happen frequently and it also causes my turn signals to stop working too. Make sure to use a 15amp fuse.....Hope this helped

try the ignition module.

look under the hood in the big fuse panel and look for High beam headlight relay the relay is more than likely bad

you ether have a coolant leak or one of these are the problem thermastat,fan clutch,water pump,radiator, try this start car when it reachs normal temp open hood and pinch the top radiator hose if it is hot water is flowing thermastat is good now open radiator with a towel slowly while it is runing see if the water is moving if it is you water pump and radiator are good, now at some point in this time you should have heard the fan get loud if not your fan clutch is not work it mounts to the front of your water pump and is normal to go out because they lose about 250rpm a year which does not give them much of a life, dont forget to check your heater hoses they could be leaking

These are notorius for cracking the intake m anifolds, they are plactic, just had one in the shop a week ago, look around the thermastat housing for cracks, I hope this helps you

it seems you have to seperate issues here. fiirst let's start withtthe over heating. you stated that you have replaced the pump,thermosta,fan,clutch,all the hoses, and core. now my question to you is did you route the belt so it's circulating like it should? is it steaming out from under the hood? to be quite honest the vehicle should not even be close to overheating after driving only 3 miles. there is a possibilty that you have a bad sending unit for the temp if it is not steaming out from under the hood. your upper radiator hose is hot this tells you that the thermostat is operating as it should. the fan should be turning clock wise as you are looking at it from the front of the vehicle.when you fill the system with coolant make sure that you have the heater on high and to the hot setting. check to make open sure you have plenty of coolant and that the radiator is free of dirt and bugs.. now as far as not having anyheat in the vehicle check the fuse for your climate control. look under the dash and make sure you hooked all the cables for your fresh air door and blend door. when you changed the core did you connect the hoses in the right place?after you have checked all the hoses and the coolant is as full as can be and the heat is turned on to max ,keep the radiator cap off and start the vehicle wait for it to get hot check the upper radiator hose to see when the thermo stat opens you should see that the coolant should go down in the radaitor. do these things and check back with me on the results...please rate this help...thanks
