2003 vibe emission light
Sometimes the emission light will come on if the gasket on the gas cap is worn or dirty, thus not sealing properly. If it doesn't look worn, then try cleaning it.

2003 Pontiac Vibe no tail lights, brake lights and turn signals work just fine. The dimmer switch does not dim the dash lights but does work the dome just fineand the lights for the Heat/AC are off.
The tail lights work off the headlight switch, and there is a fuse for the tail lights. Make sure the fuse is good, first, a 15 amp (blue) fuse in the instrument panel fuse block. Then, you might have a bad headlight switch. So you DO have dash lights, they just don't dim from the dimmer switch? In the wiring diagram, there is a green wire from a "tail light relay" (in the "Junction Block-Right Instrument Panel") that carries power to all the exterior lamps, as well as having a splice to the Instrument Panel Cluster (illum. bulbs), and to the lamp dimmer, and to the radio bulb. To do any further testing, you would need a voltmeter or a test light, so you could chase down this power loss. Good luck.

Turns over wont start
You need to figure out what you do not have that an engine needs to run. What is the fuel pressure at the fuel rail? Do you have spark when cranking the engine? Are the fuel injectors operating? Do you have ample compression? When you figure out what you do not have, that will tell you what you need to fix.

2003 vibe shudders above 60 mph
first, don't go 60 mph. next, are your lug nuts tight, wheels may need balanced. check front end tie-rods, idler arm, etc., this is unsafe, have your local mechanic check it out for you, make sure your lug nuts are on tight first.

A c blows warm
the ground is through the compressor body
unless you have gotten pressure readings , the gas is not enough or excessive It would appear that you added the gas by the can and not by pressure gauges
there are 2 pressure switches in the system
one is for excessive pressures and the other is for too low pressures and both switch of the compressor action
take it to an ac specialist shop and have it diagnosed and gassed properly

Pontiac vibe ignition switch? Intermittent dash
Basic electrical problem . loose connection on a ground circuit ,high resistance . There are no magical fixes for automotive electrical gremlins . Finding electrical wiring diagrams an voltage drop testing the electrical circuits is the only way to find the problem .
When the ignition switch is placed in the Start position 12 volts is supplied through the Park/Neutral Position Switch or Clutch Pedal Position switch to the switch and coil side of the Starter Cut Relay. If theft is not active the Theft Deterrent Module grounds the control side of the Starter Cut Relay closing its switch. Power then travels to the coils side of the ST Relay with ground at G200 closing the ST Relay. Power then flows from the Main fuse in the Fuse Block - Underhood through the switch side of the ST Relay and then to the S terminal of the Starter Solenoid. Ground is found through the engine block.

Knowing how the systems work is one of the first priority ! Learning how electrical systems work .
Learning how to read wiring diagrams an use them for pin pointing areas for testing .
Check for DTC'S - diagnostic trouble codes , this should be one of the first steps .

Front brakes are sticking on
Vibes have had a number of problems, so this could be one of them. These brake systems are ultra-sensitive to contaminated brake fluid - make absolutely sure they completely flushed the system and replaced the brake fluid when they replaced the master cylinder.

2003 vibe will not start
It has good spark then? Have you pulled a plug or two after prolonged cranking to see if plugs are wet with gas? You said pump was working, have you checked the fuel pressure? Nothing in your comment about the injectors-that's why I asked if plugs were wet.
Check the fuse for injectors, verify that power is available at all injectors with key in ON. You can check the injector circuit with a "noid light" available at any parts store-different sizes, so get the one that fits your injector connector. Just plug the light in and crank the engine over. If circuit is good, the light will blink. If it doesn't blink or if it lights up and stays lit-the circuit is not right.
All of this is to see if injectors are pulsing and spraying fuel. Do the same with spraying starting fluid into the air intake and cranking motor. If engine now runs for a few seconds, then you know it was a fueling problem.

Do you know what Camshaft Actuator System is ?
The standard compression pressure is 1,400 kPa (203 psi).
The camshaft position (CMP) actuator system enables the powertrain control module (PCM) to change camshaft timing while the engine is running. The CMP actuator assembly (5) varies camshaft position in response to directional changes in oil pressure. The CMP actuator solenoid valve controls the oil pressure that is applied to advance or retard the camshaft. Modifying camshaft timing under changing engine demand provides better balance between the following performance concerns:
• Engine power output
• Fuel economy
• Lower tailpipe emissions
The CMP actuator solenoid valve (3) is controlled by the PCM. The crankshaft position (CKP) sensor (4) and the CMP sensor (1) are used to monitor changes in camshaft position. The PCM uses information from the following sensors in order to calculate the desired camshaft position:
• The engine coolant temperature (ECT) sensor
• The mass air flow (MAF) sensor
• The throttle position (TP) sensor
• The vehicle speed sensor (VSS)
This mite be something to look at , Is cam timing advanced or retarded . The ) CMP Actuator Assembly !

No power to diagnostic port or fuel or ignition or starter pulse 03 vibe any ideas
All these have different fuses, except a main fuse that supplies power to the different fuses. Check those first. Check power from the battery to the fuse panel. Could be a bad fuse panel. If you check voltage with a volt meter, does it show any voltage at the fuses? If 0, then look to the wires first. If they show varying voltage(like2,3,4.5,or 6) suspect the fuse panel. The voltage should be 0 or battery voltage.
