RE: 93 astro-fuel pressure
The fuel pressure on a throttle body injected engine should be about 14 - 15 psi. (The official spec is 12-15, but they won't really run at the low end of the scale). That van doesn't have a fuel pressure test port made on it, so you'll have to put a gage between the filter and the engine to test it. Also, be sure to check maximum pressure by pinching the return hose (at tank) with the pump running. It should be at least 30 psi. HTH.
