2000 Pontiac Sunfire. What would cause this and had anyone else had this happen or something similar?

The problem is the pipe that has split or separated under the fuel filler. It is supposed to be an airtight seal for the fuel and the fumes from the fuel. All called the Evaporative (gas vapour) Emission (gas NOT getting into the atmosphere) System. Nothing to do with the other items you mentioned and all caused by the above.

2000 pontiac sunfire trac off and check engine light both come on and than car stops when i crack it again it cracks right up and lights are not on for a couple of days. i have had fuel pump thermost

Check the wiring harness near the ECM for corroded wires and or lumps in the wires. I believe the ECM is located under the front passenger fender on this model and is exposed to the elements so will cause problems. You may have to remove the front part of the inner plastic fender to access it or go from underneath. Some newer models the ECM is attached to the top of the engine.

When driving my 2000 pontiac sunfire 2.2 the traction control light and engine light come on and it will like misfire

There is an OBDii code reader available on ebay for $10. Get the one with the lights and there is blutooth model that can download app for your phone. Other than that you be guessing and changing parts.Try running a new ground wire from the neg side of battery to the body and to the engine and check wiring, sounds electrical. I beleive the ECM is located inside the front part of the fender on passenger side and it's exposed to the elements, be good to check this for corroded wires and connector as well it the harness may be rubbing up against the body in that location and shorting out. Look for lumps in the harness at the point it connects to the ECM again should be located in the front innner wheel well behind the headlights but you will need to get to it from underneath or remove the inner plastic fender. Some newer models the ecm is on top of the engine and check the harness where it runs along the body as it may be moving and baring wires at that location or some wires may have corrosion and bad connection.

Dash gauges not working

Coming here was a pretty good start... FREE What you need to do is AVAIL yourself of the circuit drawings & TECHNICAL SERVICE BULLETINS (TSBs)... The ABSOLUTE BEST drawings are found in your model and year's FACTORY+WORKSHOP+REPAIR+MANUAL... (excepting FIRE ZONES & extreme winds) ... I strongly recommend paper CIRCUIT DRAWINGS Typically 2000 Sunfire will include several different GM clusters and the actual FACTORY manuals are not cheap... (But few really great things... rarely are... ). BEGINNING progress can be accomplished with FREE drawings & TSBs from BBB Industries website (registration is required ... as these are real documents). BBB Industries Premium Alternators Starters Power Steering Products SUCCESS comes from careful & CORRECT HANDLING of sophisticated semiconductor circuitry (meaning: you must beg, borrow or buy an anti-static wrist-strap... & use it ) $6... Amazon com Rosewill ESD Anti Static Wrist Strap Components RTK 002 Black... The slightest static spark... (you might not even feel) is enough to completely destroy any SEMICONDUCTOR... READ MORE about ESD (Electro-Static Discharge). Incredibly important... Electrostatic discharge Hope this helps... If it does NOT ... Comment me back (we can do this... It is a pretty cool Sunfire) Carnac the Magnificent
