1994 ford ranger mass air flow problems

Ihave a 1994 ford ranger with 2.3l 4 cylinder engine. i have replced the egr valve, egr relay and now is giving me a mass air flow error when i read the computer. the engine makes a reving noise and doesn't have good power. my gas milage has gone from 20 mpg to 15 mpg. also if the vehicle stalls when backing up i can't start the vehicle and the computer gives me an open fuel pump relay. if i let the truck sit for about 10 minutes it will start. if anyone can help me i'd appreciate it.
thanks pat

Please help. I desperately need to know how to read the computer on my 93 ranger. There is an ECC TEST module with 6 connections near my power distribution box on the left. I've been getting a check engine light occasionally and have been wanting to know how to read the codes. http://dalidesign.com/hbook/eectest.html has some info but I'd like to know how you do it. Please post here and email me at jiml@hal-pc.org with your procedure.
thanks
Jim

I have 94 Ranger 4.0 with similar symtoms: will stall sometimes after releasing accelerator or sometimes after shutting off the engine if I try to restart immediately it only cranks. If I leave it sit for 10 min. it starts OK. Sometimes when idling for no reason the RPM increases a little as if it was about to stall and the computer gives it more gas.

How did you finally fix the 93 Ranger?

Thanks.
