I tested the spark by taking spark plug wire off and cranking the car and there was no spark. I checked car for compression and it had strong compression. I took the 5 pin electrical wire connector off the coil pack and checked it for voltage to the coil from battery and it had 11.7 volts on it, so power was getting to the pack. I also checked the risistance on the coil pack by hooking up my multimeter to coil #1 and #6, #3 and #4, #2 and #5, and each coil hookup had 3600 on them. And I also tried the led light hook up to the 5 pin connector from the coil pack. I hooked up the positive wire to the #5 pin and negative wire to the #2 pin and the led light did not flash when I cranked the car like I was told it was suppose to do if the coil pack was getting a signal from the ecm, or crank position sensor, I also done this with the 3 and 4 pin on the connector and still no flash from the led light. What is my problem with this car and what I need to try next.
check for codes
Electronic Control Module (ECM) recognizes faults (open circuits, short circuits, missing signals, or a continuously applied signal voltage) in the following circuits/components.
Crankshaft Position (CKP) Sensor
EGR Frequency Valve
EGR Temperature Sensor
Engine Coolant Temperature (ECT) Sensor
Fuel Evaporative (Frequency) Valve
Heated Oxygen Sensor (HO2S)
Hall Effect Sensor
Idle Air Control (IAC) Valve
Intake Air Temperature (IAT) Sensor
Throttle Position (TP) Sensor
if no codes check for pending codes
suspect bad coil
suspect crank sensor

Hi, and thanks for getting back to me.
Will my car give a code being that it is a 1995 model. The engine in this car has been changed out and every since then the car has not started. Will it have codes on it yet?
And when I tested he 5 pin connecter that hooks up to the coil with a led light and the light did not flash when I tried to crank car, does that matter that the coil is not recieving a signal, and that maybe the coil is still bad? When I hooked up the led light to the 5 pin connector does the led light suppose to flash when car is being cranked? The led light does come on when hooked up to 5 pin connector when car is turn on but will not flash.

95VW in the usa should be an OBDII ready
and an OBDII reader can be used
check for codes and pending codes
recheck wiring harness and inspect crank sensor
