Full-size 1990 Bronco will not stay running

I have replaced the fuel pump, regulator, egr, throttle position sensor, I am running out of options! It starts up and then almost immediately stalls and seems to have a loss of power when trying to keep it running. Please help!!!

Will it stay running if you give it a little gas? if so It may be a idle air motor (aka iac valve).
Also I was wondering if you were changing the parts you listed just on a guess, cause someone said to, or if they tested bad. Hopefully it was the last.
good luck,

Have you changed the fuel filter? This needs to be done routinely and can cause this problem.

Re: Full-size 1990 Bronco will not stay running

STOP throwing part$ at it. It's the most expensive & least effective way to fix anything. Spend that money on tools, like a fuel pressure gauge (~$35), a digital multimeter ($8-80), a vacuum gauge ($35-50), & a Haynes manual ($14 PN 36058 w/light blue cover). A screw-in compression gauge would be another good investment, but it can wait.

Another important diagnostic tool is a paperclip - use it (or any jumper wire) to pull the codes.
