If you have a inductive timing light (hope so), clip it on the black wire on top of the ignitor on the valve cover. For details go to
http://www.q45.org Under timing there's pix.
If you don't have one; I've seen a spark checker at Autozone -a little pen w/a light in it that shows if there's a spark it's real cheap. Not sure if it will work on a Q though, I have one but never tried it on the Q car, since it's made for plug wires.
EDIT: How old is that pump? Did you try through the filter and before?From what I read around here spark probs are rare.
Do you get a code at the ECU?I'm running out of ideas...
