maybe. depends on how badly you failed. new plugs could make the diff. so could new air filter and an oil change. oil stores a lot of hydrocarbons. if you failed by a lot more costly action may be necessary.

Make sure the air is bled out of the cooling system,and replace the coolant sensor,not the sending unit,they are two different things.

sounds like a broken wiper transmission (the arms that connect the single motor to the 2 wiper arms.)

Could be a bad motor mount. Would have to be inspected visually.

sounds like its vapor locking try losing up the fuel cap just a little and if that helps replace it!! and change the fuel filter!!

I would place the wire through a predrilled hole you will drill out and seal it with a 3M sealer to prevent any leaks. Pick a suitable area where it will be easy access by the drivers firewall area

your probley hearing the starter clicking try jumping it sounds like a dead battery

check the crank sensor

hi,
Im going to take a stab at this and say to say fuel lock. this condition arises when the fuel filter gets clogged and the fuel stays pressurized in the system and causes the computer to not energize anything because there is fuel pressure present already. try replacing the fuel filter. if you still have a problem your best bet would be to take it in and have them put it on a computer rather than nickel and diming yourself good luck

Remove spark plugs, clean and regap. (LABLE THE LEADS TO THE CORRECT PLUGS) Or, replace plugs and set gap to GM specs. Any GM service center will tell you what the gap should be. It is probably between 20-30 thousands of an inch.

make sure tire size is correct. if so, then there may be a faulty speedo sensor.
