I hope you used all factory parts, it makes a difference. Compression test? nope valve guides I really doubt it
have someone do a smoke test for vacuum leaks you can have a sucked intake manifold gasket smoke test is really the only way to find a small vacuum leak

It could be a clogged fuel filter, bad gas. Or if you have done alot of modifications to it, the injectors may not be able to keep up.

SOURCE: Code 300 and 330 on 2001 Pontiac Grand Am

po330 is a bad knock sensor, the sensor will cause, sluggish engine, poor acceleration, poor fuel economy. the signal is sent to pcm and the timing is retarded to compensate for the severe detonition. on 4 cylinder models, the knock sensor is located on the rear firewall side of the engine block, below exhaust manifold.on v6 models , the sensor is located on the front radiator side of engine block above the oil filter.

Spark plugs,wires and injectors, have nothing to do with your problem

PO303 is a misfire on cylinder #3
You may have an individual cylinder coil for that cyl or a coil pack for
several cyl,don't know the engine you have.

You may also have other issues that are causing the shaking

Wont start. it has injector pulse but no spark


is there power and ground to the coils?

If there is injector pulse than the crank sensor has to be good. Injector pulse and spark are both calculated off from the signal from the crank sensor.

Checking for power and ground to the coils is a good place to start. If that checks out than either there is a wiring issue in between the PCM and the coils or possible the PCM has failed.

Put new fuel pump in 1992 firebird. i have fuel to fuel rail and spark injectors are not firing thankyou for any help


On your car the ECM is set up with two quad injector firing sequence. All even numbers and all odd numbers. It is rare that both would go out at the same time. The ECM grounds the injectors, so I would check for power going to the injectors first. This could be a fuse or a bad wire. One wire feeds power to the injectors until it reaches the engine. this is a start, so let me know. Randy

I have a 1996 pontiac firebird with the 5.7 L it has lost some of the power and smells like fuel and has black smoke on start up. The fuel system has been worked over and there are no codes thinkin maybe...


Neither cat nor sensor.
You have a leaky fuel injector (stuck open).
Black smoke is unburt fuel.
Obtain a mechanics Stethoscope (like a doctor's steth, but has a rod onthe end instead of a disc).
You will find the faulty injector quickly.
Best to replace it.
(By the way, white smoke is Water and blue smoke is oil)

97 firebird formula hard to cold start


Check the cold start injector useing a digital multimeter with a bar graph. Unplug the injector wires and insert the probes into the wiring plug, crank the engine and the bar graph should pulse if it does remove the injector and with the wiring reconnected and the injector held over a suitable container crank the engine and observe the spray pattern. If insufficient replace injector. This should be a starting point at least
