Hi Dan,

If you hear it running and you're sure it is the tank pump you hear, checking the current won't help you to know whether it is getting fuel to the main pump. For example, if the rubber hose inside the tank has ruptured, it may be pumping fuel but most is falling back into the tank.

To answer your question, I think these lift pumps draw a little more than an amp, not much really. For a closer number I'd have to assume the brand I am using is typical and measure it again, rather than depend on my memory. Along with the oxygen sensor heater, fuse 4 may be seeing 2+ amps.

Either way, the symptoms of this sort of vapor lock can have other causes. One in particular is specific to the 91-92 and early-year 93 cars. These model years run the whole fuel management system through fuse 6, and with just a tad of salt air or leaky windshield corrosion can cause local overheating. I've got some pictures of that here: http://cleanflametrap.com/emfuse.html

And, depending on what symptoms you've related, we still don't have a firm call on ignition or fuel.

It's tough when you can't reproduce the trouble, and it is someone else who drives the car.
