Probably also worth pulling the relay and replacing after a squirt of WD40 (repeat as necessary for other local connectors). You might have a slightly duff connection to the relay due to a bit of corrosion (maybe all that washing to get the bike looking so pretty!). If it primes when you tap the relay that pretty much rules out a stalled pump motor but could still be a duff connection.
