Sounds like your cooling system is full of air. Make sure you have it bled off properly. You could also have a blown headgasket, or have a DEX cool blockage in the system. Either way, it sounds like you need to take it to a shop and have it properly diagnosed.
try checking your catalyctic converter
You need to have your check valve replaced.
Had same problem on my 03. Replaced the fuel and air filter and had plugs replaced. Ran like new after. Dont know which its was but a place to start.
Sounds like your theft deterent system is engaged; for that you will need to go to the dealer (tow car to dealer). My 1996 had the same problem. They will have to replace the module in the dash or re-work it.
Check ignition switch, common problem.
Check plugs and plug wires---worked for mine.
The alternator is going bad, may need to be replaced soon
If it starts at all I'd say it isn't the key, check the MAF sensor.
why does the gas keep backing up the filler tube when pumping gas in my 1998 intrigue
mine did the same thing i replaced the crank sensor and it runs fine
This sounds like a bad ECU. Has it ever been replaced?
IAC: Idle Air Control valve. Needs replaced.
