I have a 1999 Grand prix. The car wont start but it tries to . You can hear the fuel pump kick on but the car doesnt start. What could be the problem?

Check for pressure on the fuel rail at the schrader valve. Which is located on the rail. My guess is you have low fuel pressure and have faulty fuel pump. Pressure should be around 50psi.

1999 Grand Prix 3.1 V6 having problems with the cooling system, the low coolant light comes on even after fluid is put in, while driving it sometimes runs on the hotter side however if I idle too long it...

sounds like you might have air in the system, when cooled loosen the rad cap but not completely and run the engine until the fan comes on run for another 2-3 minutes then CAREFULLY with a rag remove the rad cap, Don't worry it was loose and won't be under pressure, check fluid level in rad as well as in over flow reservoir if low fill to proper level.

Where is the AC Low pressure valve on a 1999 Pontiac Grand Prix?

sometimes its behind the alternator real close to the firewall. Find the bigger of the two hoses and pipes the low side is always bigger. Also the cap is blue and the fitting for the charging can will only fit on the right valve.
