1996 Pontiac Grand Am 6 cyl Two Wheel Drive 120000 miles

I had it put on a analylist machine it will not start in cold weather. The outcome was 4 things defective or loose gas cap.I bought a new one. EVAP canister or hose cracked-not connected. Purge or vent selenoid defective. Vaccum leek at engine. What does that mean and where is it, how much do repairs for this cost.

I should say do below and get back to me and tell me what's missing fuel or spark-? A major vacuum leak will prevent the engine from starting.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself, distributor pick-up, control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time
