The smoke might be white, blue, or sooty black.

If white, some such vapor is normal on a cold start, but lots and lots indicated a water leak into the inlet manifold or a cylinder, probably a gasket leak. If a head gasket leak, this would cause quick overheating.

If blue,this is oil smoke from worn piston rings or worn valve stem seals. Oil can also get into the inlet manifold via a faulty PCV valve. A compression check will tell you more.

If sooty black, this is over-rich fuel mixture, and may be due to a number of things, such as a faulty temperature sender, a faulty fuel pressure regulator, or a stuck-open injector.

where do you want the fuel line to go or from , there should be a fuel pump on the side of the block on the passenger side in the front there should be a steel line from there to the carburetor, , if you are referring the tank there should also be a long steel line from the tank to that pump which is standard size is either 5/16 or 3/8 I would never run a rubber hose that length , or no longer than a foot because of safety issues hope this helps

Coolant level low, thermostat stuck closed, radiator fans failed, head gasket leak to coolant jacket

After checking the coolant level, look at the radiator fans when it is very hot to see if they operate.

If OK, have a mechanic do a simple check for combustion gases in the coolant, and a compression check on all cylinders. This is not expensive.

If OK, change the thermostat and flush the radiator.

My Buddy had the same issue, it was the temp control sensor. An easy fix.

Is a tuneup in order? Usually that will help you with fuel mileage also.

Beyond that, first thing is to replace your air filter.

52 is a faulty knock sensor signal. The connection there may be loose or broken. 71 is an EGR temperature signal fault. Again the connection may be loose, or the EGR temp sensor faulty, or the EGR vacuum switching valve faulty.

Possibly either your A/C idle up vacuum valve has failed, or the Idle Air Control valve (IAC) needs cleaning.

Take out all the spark plugs, remove the inner right fender plastic skirt, put the trans in neutral, and with a socket wrench, try turning the engine by the crankshaft pulley bolt. If it does not easily turn, it is seized.

Aw, were you guys out spoofing around? Maybe moisture got into some ignition electrical connections. If it has a distributor, make sure that the inside of the distributor cap is dry. Check for a blue, snapping spark on a spark plug wire end to see if it is an ignition problem. If no spark, you will need to diagnose the ignition circuit or system.

if you want to know how to test your coil,you can check if there is power on the wire that come from the coil to the distributor .
