How do you know that you have fuel? Are the plugs wet with gas? Do you have a FP guage on it? The pump should not run constantly, it should turn off if the engine is not turning. If you just turn the key to on, and dont try to start the car, does it turn off after 2-5sec? Did you mess with the timing? I take this to mean the engine turns over, but doesnt start. Is that correct. We need more info, its hard enough to figure it out when you are not there. Did you work on anything right before this prob ocurred?
