I have a 1999 Ford Escort SOHC....I was driving down the highway and it started to fall on its face under load....then it died and wouldnt start....I changed the fuel filter and pulled the fuel pump out and inspected it and the tank.....the pump and tank were both filthy....so i cleaned out the tank and replaced the pump...i attempted to start it and it fired up and idled for about 5 seconds then died again and will not start...I have good fuel pressure from the pump all the way to the fuel rail...I found that i have fuel in the engine oil...so i pulled the fuel rail loose so i could see the injector spray and see if one of them were leaking......none are leaking but the fuel coming out of the injectors does not mist it just comes out in a stream....and all four injectors fire at the same time.

This is a sequential injection system so they do not fire all at the same time unless there is a problem. This is also a module controlled, variable pressure fuel pump system.
I would start out by reading stored codes and see if that gives you any hints.

It had a code for a fuel rail pressure sensor. And the injectors are firing all at the same time so i know there is a problem....I justr need to know what drives the injectors.

The computer drives the injectors but you need to fix that fuel rail sensor problem first.

Start from the beginning........
All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

I have spark, good compression, and good fuel pressure.......I got it to start but as soon as you touch the throttle it dies...it will start back up but does the same thing......

What was the fuel pressure reading?
