1994 saturn sc won't start after driving couple of miles

Possible fuel pump problem. Check pressure at port on intake.
If the hose is long enough and made to withstand the pressure, it can lay on the windshield, held by a wiper blade to be read while driving.

You have a lot of sludge build up . There is a product in most auto parts stores that you add to tour engine oil. You run the engine for a short period of time. Drain the oil and replace with fresh oil and filter. Depending on the amount of sludge you may have to do this several times. A Good thing to do is remove your Valve cover, If it is covered in a thick or even brittle black goo it means that the oil has not been changed every 3,000 miles as recommended by ALL manufacturers. And you may have bigger problems down rge road. Don't forget to replace valve cover gasket.

Pulling plug wirs is a big mistake unless you know what your doing and you don't sound like you do. It sound like a frost plug is corroded away. You should be able to start your engine even if it had no coolant at al. the coolant only cools the engine ,it does not stop it from running.Now you need a wiring diagram for your engine to see if you have the wires in the right place.......otherwise the engine will not start ever.Worse case ....it could be a head gasket and if that is the case give it to someone whom wants a free car to work on themselves...............Ken

check the coolant temp sensor

put a drop tester across the battery its flat for whatever reason or had its life so try charging it with a trickle chearger for a couple of days and if still no start then renew it

Check to make sure that one of the pulleys are not sticking on your serpentine belt line, or better known as the belt drive. Such as an alternator that is that seizing up, or a bad power steering pump.

you could get 300,000 miles on just about anything but its a chance nevertheless

personally, I have not seen many of these with more than 200,000 because there were head gasket issues at 150,000 or timing belt issues at 100,000

therefore, we assume that these were already taken care of or they are about to be in need.

Unless the cost of the vehicle is $500, I might consider something else

sounds like the feul pump is getting weak

yes the choke is not working right,,,
just do as your doing,, hold down the pedal,, its cheeper that getting it fixed,,,and you try and nick it?

crank sensor located behind engine, cost at advanced auto 21.00 dollors.
