1990 Jetta Gas engine dumping Fuel in Cylinders

[VW Petrolero]

I have a 1990 Jetta with a Gasoline engine that I have to find the problem why is dumping too much raw Fuel into the Cylinders.
Somebody has a problem like that before.
Any suggestions is really appreciated.

They had this problelm on Klick and Clack last summer. I think it's just the injectors.

Check the ground at the valve cover, on the end towards the transmission. Check the full throttle switch on the throttle body to be sure it isn't stuck. Check to be sure the air flow meter door isn't somehow jammed open.

You didn't give us much to go on, is the ECU keeping the injectors energized all the time? I doubt all four injectors suddenly stuck open. They pulse all together, this is not a sequential EFI system.

Thanks for your replies .
No the Throttle is not stuck open or the flap at the AFM.I even tried other AFM.The Fuel Pressure regulator also is not sucking gas .I think the ECM is ordering all the injectors open.I 'll try tomorrow the Fuel Pressure & go from there.
Please keep the ideas flowing.The more suggestions the better.

I had the same problem on another make that used L-Jetronic injection. In this case the computer was fried.
