2007 Pontiac Sunfire - Answered Questions & Fixed issues

theft loc triggered worn ignition lock cylinder

Its likely that you have either a bad ignition switch or a bad neutral safety switch (if stickshift, clutch switch) Try starting in neutral...if it starts, change neutral switch (jump across clutch switch, check starting in neutral with your foot on the brake) Ignition switch is on top of steering column under dash.

The starter solenoid is wearing out. You can buy new contacts to repair it or you can buy another starter and get the solenoid with it. Either way, you will need to remove the starter from the vehicle.

A P0455 is a Evap system (large) leak. Sometimes this code is set by a missing or bad fuel filler cap.

bad bulbs, bad relay

if there is no leak, change the clutch master cylinder .

hi,

you can try your emergency flasher switch and make sure its completely off, sometimes that switch will interfere with turn signal operation, just an idea

good luck

The connections between the starter and the engine is not good, is unstable...

Maybe the starter is not notify to the engine.

It's hydraulic but it side mount trans so it has two cable that for thought fire wall under shifter to the linkage mine is gone bushing are shot and I've done slave cylinder 3 times in 3 months kinda becoming a pain as i just got car and has only 70 k miles and

Sound like the synchronizer is out for 3 and forth gears

check your negative ground cable first thing. make sure that it is clean on the battery and all the other places it attaches too, and there are several. disconnect the battery negative and clean it and then disconnect the positive too. when you reinstall them after at least 5 minutes make sure they are very tight. not to the point of breaking them but tight. check back see, turn the key to the On only then off and then ON ( not start) shut it off and then start it as normal. is your check engine light on?

Yup

There are no normal specifications I explain. R134A refrigerant act different He changes pressure (status) with humidity percentage level. One day the pressure is this and the next day it is different. The pressure chart will tell you that.(From GM technicians courses)Or GM Dealer Hope it helps.

don't know about this exact car, but most brake calipers use either a 3/8th inch allen (hex) head or a T-50 torx head bit. The Hex wrench is what I would get without seeing this. I have also used a ratchet extension on some cars.

I suggest you try one of those instant download manuals. My brother( a mechanic) buys when he can't fix some technical issue with the manual at www.reliable-store.com . A lot of mechanics actually do this. Website is very good for this. Must try it !!

try hold up the key while starting, shot in the dark. if it startes remove extra items off key ring

check fuel pressure, if low change fuel filter. cycle key 3 times on and off ,before going to start

Sometimes it looks crazy too. But first look for good grounds Battery, cluster gauge you will have to retrieve the faulty code with a scanner that can read the code. Hope it help

You have air in the system and that prevents the thermostat from opening. Once leak issue is fixed you have to add antifreeze and squeeze the rad hoses repeatedly until the air is forced out. Run the engine up and down from 2 or 3000 RPM quickly to force air out, shut it down and refill when cold until it starts throwing heat you will still have an air lock.
