Well, like most things, this could be a number of problems. In my case it was because the car had been sitting............wait, you said no pulse. As in the injectors aren't firing? -or- as in the car is dead, no worky?

Only reason I ask, is that's two seperate problems and I don't want to give you a long dissertation on the wrong fix.

What I want to know is, where in your Nissan manual does it say to give the injectors a good whack!?!

hehe...

I'm glad you got the problem solved. Now check your ground connections, and I've only heard good things about running extra ground wires (smaller) from the engine block/head or whatever to the frame or body.
