Yes, I experienced the same thing with mine... you have to losen the 2 motor mounts on that side and lift the motor up about 3 ". I worked at a garage so I had access to an engine hoist. Try using a jack from underneath. Nice engineering from Mazda!!!

My '91 626 did the same thing. I tested the throttle position sensor, and it was good so that wasn't it. The other likely culprit is the Idle Speed Control valve, or Idle Air Control valve, which is a $500 part new (more than I paid for the whole car). I pulled one off a 626 at the salvage yard and got it for 3 bucks, put it on (it's an easy DIY, just 4 philips screws holding it to the intake manifold), however I can't be sure that solved the problem, since I haven't run the car much since then. It would seem the most likely cause, tho, and a cheap fix if you go used. Other possibilities: O2 sensor or Mass Air Flow sensor?

You may have to dig deeper for a vacuum leak. It's possibly the intake manifold gasket. Try spraying some starting fluid around the intake manifold. Also try disconnecting the brake booster and plugging that hose, the diaphram in the booster could be ruptured, causing a vacuum leak. Check the PCV valve and hose too.

The fuelpump is located in the fueltank and is accessible by removing the rear seat squab. Under the squab is a service panel that will have a few screws holding it down. remove the panel and instead of removing the pump try giving it a firm rap with a hammer handle or piece of solid wood taking care not to damage the wiring or fuel lines exiting the top of the pump assembly. This may be enough to get the pump to work again.
