well first on the 1.8 the feul pump does not run for the 1.5 second, it runs when the starter is cranking
check the double relay one is the main relay the other is feed from the air flow sensor pump contact
you can pull the cover off of it and push the relay by hand, with the cover off the one you want is the left one as you look at the relay side ( as opposed to the circuit board side )
if that does it then the problem is betwwen the air flow pump contact and the relay
check the big red wire from the relay pack to the battery ( about 8 or 10 guage )
while you are in the relay chech that the contact is good mine burnt off and i hard to solder it back on
also the relay on the reg board does nothing on a afc fi system but it can be jumped out to make it run
if you still need more help email me
