Question about Volkswagen Golf

1 Answer

My 1999 Golf (ABA) will not start - no spark. It worked perfect last week, but did not start after a stop at Home Depot. It did start after 6 start attempts, then started and drove 3 more times that day, but quit Tuesday morning and has not started since. It has voltage to coil and distributer. I tried the LED continuity test light between pins 2 and 3 going to the coil - when ignition is on (per Chilton?s manual) - LED lights, even while cranking, but it?s suppose to pulse, not stay constant. I replaced the Camshaft Hall sensor, but still no go (even though it looked like I saw a tiny pit in the seal under the actual sensor). My friend had an OBD2 tester and gave me a PO322 code. While looking up on the internet I saw that it could be the crank sensor (which I've bought, but not removed from box yet as it?s $85 if I open the box). I looked online. It says that the crank sensor should have a resistance level between the contacts (there are 3 ? I saw infinite resistance between any combination of contacts, and each to ground). Next I tried the A/C voltage crank test, I did get some A/C voltage generated back while cranking - between 2 of the pins. Do you think the crank sensor is bad since it has infinite resistance, even though it is generating some type of signal at my Voltmeter? If not can you tell me where else to look? It's been a week, and I need my car back :( Please Help!

    Thank you so much. I did not know much about VW Ignition Wiring/component testing, but with your expert knowledge in engine component diagnosis, I was able to quickly repair my vehicle. It was my crank sensor that went bad, per your diagnosis. You saved me both time and money. I'm back on the road. Thank you again!!!

As per the test you mentioned it indicates the problem of crank sfaft sensor. Infinite resistance between any combination of contacts,This shows that crank shaft sensor is faulty. Other possibilities are voltage at coils and distributor and you mentioned its voltage.Also check the spark plugs itself.But as it showed code p0322 so its pointing to replace crank shaft sensor. Replace the sensor it will solve the problem. Thanks. Keep updated for any more query. You can rate this solution and show your appreciation.

    Thank you very much for the confirmation on the sensor. It took a while, but I removed the Crank Sensor, and tested it again, still infinite resistance across all contacts, so it looks to be bad. I did have to remove the engine mount to get to the sensor. I opened the box to me new sensor, but quickly found that they sold me the wrong part (wrong jack at end of cable - mine was rectangle, theirs was oval). I called them back. They will get me the new cable on Monday, so I plan to install Monday. If this works, then I thank you very, very much and will submit a very positive result. Right now I'm stuck in limbo over the wrong part.

I suspect from your diagnostics described you may have faulty spark plug wires.start[or crank]engine in the dark ;observe plug wires,look for sparks from wires to engine,if evident,replace wires.[one at a time to maintain proper order].
