99 Cabrio Starting problem!

99 Cabrio Starting problem!
Here it is guys! I have this 99 Cabrio in the shop and myself or any of the techs have been able to find out what the problem is! Initially the distributor was replaced due to a clip being cracked and would misfire from the inadequate contact. Upon attempting to crank we were not getting enough fuel and replaced the fuel filter. Now the car attempts to crank and but it turns and fires but immediately shuts off. The vehicle will not cycle and idle! When I try to pump the pedal it's almost as if the throttle is inactive. Before any repairs were attempted we hooked up the scanner and returned 12 codes which I will detail below. I disregarded most of the codes due to the distributor being crack it seemed like they were all from that one symptom. We have been unsucessful in cranking the car and we are now past due on our deadline! Please help us out! AHHH!!! Damn thing!

RE: 99 Cabrio Starting problem!
What about replacing your throttle positioning sensor, that would make up for the throttle and computer not talking to each other. Was the computer reset/cleared before connecting scanner, you may be retrieving old codes. Taht's the adibvce I have for you...good luck.

Special Notes:
In MY 1995-2002 (?) in Europe at VW diesel cars Mass Air Flow (MAF) Sensor (G70) had the bad reputation of slowly losing his performance, causing loss of power. It's not a matter of defective or breaking down, but it is filthy/dirty (not easy to clean). You can check functionality by making a log in [01-engine], Measuring Value Blocks (MVB) 08, group 003 (3e gear, full throttle, from 1700-4000rpm).

An excessively low voltage from the sensor is sent to Engine Control Module (ECM).
Description:
The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).
The Mass Air Flow (MAF) sensor is placed in the stream of intake air. It measures the intake flow rate by measuring a part of the entire intake flow. It consists of a hot film that is supplied with electric current from the Engine Control Module (ECM).
The temperature of the hot film is controlled by the Engine Control Module (ECM) a certain amount. The heat generated by the hot film is reduced as the intake air flows around it. The more air, the greater the heat loss. Therefore, the Engine Control Module (ECM) must supply more electric current to maintain the temperature of the hot film as air flow increases. The Engine Control Module (ECM) detects the air flow by means of this current change.

Special Notes:
This Diagnostic Trouble Code (DTC) indicates that one or multiple cylinders are misfiring, but the Electronic Control Unit (ECU) fails to identify the cylinder.
Tech Notes:
The P0300 code means that a cylinder(s) is misfiring or is randomly misfiring. Start by checking for intake leaks, intake gaskets are common caused of multi-cylinder misfiring. If no leak are found the next step is to replace the spark plugs. If the problem persist more tests needs to be done to diagnose problem.
When is the code detected?:
The control module monitors the crankshaft speed and has detected a misfire condition.
Description:
When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position Sensor signal to vary, the Engine Control Module (ECM) can determine that a misfire is occurring.

Tech Notes:
Sometimes and in some models, low battery voltage or a weak starter can trigger a Camshaft Position Sensor code.
When is the code detected?:
The camshaft position sensor signal sent to the Engine Control Module (ECM) during the first few seconds of engine cranking is out of range.
Description:
The Camshaft Position (Hall) Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module (ECM) to control ignition and fuel injection. The camshaft position sensor senses the retraction of camshaft (intake) to identify a particular cylinder. The Camshaft Position (Hall) Sensor senses the piston position. The sensor system consists of a rotating part, typically a disc, as well as a static part, the actual sensor. When the engine is running, the high and low parts of the teeth cause the gap with the sensor to change. The changing gap causes the magnetic field near the sensor to change. The change in the magnetic field cause the voltage from the sensor to change. When the crankshaft position sensor (POS) system becomes inoperative, the camshaft position sensor provides various controls of engine parts instead, utilizing timing of cylinder identification signals.

The component identifier Throttle Position Sensor (G69) may be G187 per the wiring diagrams for the vehicle in question.
When is the code detected?:
Malfunction is detected when an excessively low or high voltage from the sensor is sent to Engine Control Module (ECM).
Description:
The throttle position sensor responds to the accelerator pedal movement. This sensor is a kind of potentiometer which transforms the throttle position into output voltage, and emits the voltage signal to the Engine Control Module (ECM). In addition, the sensor detects the opening and closing speed of the throttle valve and feeds the voltage signal to the Engine Control Module (ECM).
Idle position of the throttle valve is determined by the Engine Control Module (ECM) receiving the signal from the throttle position sensor. This sensor controls engine operation such as fuel cut. On the other hand, the Wide open and closed throttle position switch, which is built into the throttle position sensor unit, is not used for engine control.
