my mk3 cranks and wants to start, but won't

[interested!]

Hi , I have just remembered a case where I had to change a blown hose and forgot to reconnect the wiring to the airflow meter . Would not start without it . Maybe worth looking at a dry joint there . Keep going .
Possibly a good idea to make a list of possibilities and thoroughly check and cross off each when done . What is left could be the problem . Even been known to have double and triple faults . Always have at least 4 gallons of fuel in the tank for testing .
