Have Volvo Questions? Ask a Volvo Mechanic for Answers ASAP
I am sorry that you have not been helped yet. I just came online and saw your question
When it will not start, have you determined what is missing - spark or fuel? If not, we need to do this first. When it wont start, spray some starting fluid or pour a small amount of fuel into the throttle body and try to start it. If it starts and runs for a few seconds, then we know it has spark but no fuel. If no difference, then it has no spark.
Do this and let me know results
