Engine Car won’t idle

Ok guys, new to this form, I have a 93 lx 5.0 that won’t idle, new maf, iac, tip & fuel regulator and it still won’t idle or run! If I unplug the maf it’ll idle just fine but falls on its face when I try to give if gas, everything is still on it from the factory except the things I replaced as mentioned. When I unplug the maf sensor it idles smooth for about a min or so then dies but won’t start immediately but does start & idle for about short time, I don’t know what the fuel pressure is but u can here the fuel pump power up and stop, does this sound like a pump problem? Or what? Thanks

You guys with idle/stall problems could save a lot of time chasing your tails if you would go through the Surging Idle Checklist. Over 50 different people contributed information to it. The first two posts have all the fixes, and steps through the how to find and fix your idle problems without spending a lot of time and money. It includes how to dump the computer codes quickly and simply as one of the first steps. I continue to update it as more people post fixes or ask questions. You can post questions to that sticky and have your name and idle problem recognized. The guys with original problems and fixes get their posts added to the main fix. :D

It's free, I don't get anything for the use of it except knowing I helped a fellow Mustang enthusiast with his car. At last check, it had more than 250,000 hits, which indicates it does help fix idle problems quickly and inexpensively.
