Thanks Mark.

When I turn on the ignition switch, the left (power) relay does click on,
but not the right (fuel) one. And the fuel pump does not come on for a
second. How do you suggest I test this? Is the ECU responsible for causing
the fuel relay to click on? How do I test whether the ECU is getting power?

Much appreciate the help!



A bientot et avec amour,

“A master in the art of living draws no sharp distinction between their
work and their play; their labor and their leisure; their mind and their
body; their education and their recreation. They hardly know which is
which. They simply pursue their vision of excellence through whatever they
are doing, and leave others to determine whether they are working or
playing. To themselves, they always appear to be doing both.” -L.P. Jacks
