I also forgot to mention. When I turn the key before starting, there is a little box above the fan shroud underneath the trim piece with the belt routing diagram, that box is buzzing real loud. Not sure what it is, it has several wires going into it. It may always buzz but never heard it when the car was running....I didnt get much time to look at it today, so i'm trying to gather as much info as I can for when I do get another chance.

That is the CCRM (constant control relay module) I believe. It houses some of the major relays like the PCM and fuel pump relays. You might have a bad ground somewhere causing the chattering, or the CCRM might be bad. You're probably not getting constant power to the PCM or the fuel pump.

Unplug the MAF and see how it runs. Ignore the CEL and any MAF related codes generated when you do this. The EEC IV system is pretty stupid compared with the modern OBDII processors, and doesnt perform the rationality checks that OBDII does so an out of range MAF often wont set a code.

89 doesnt have CKP, CMP, etc........ Its TFI/PIP ignition. TFI (module on side of dist) and PIP inside the dist are common failure items that can cause your problem, and they often will not set codes when they are failing.

I may be wrong but I don't think the '89 has an MAF sensor. My '90 doesn't, at least not where the later years have it at the air filter box outlet.

oh look ANOTHER lil old lady who only drove it to church on sundays! richer than donald trump i tell you. and yet again it only broke down after a few weeks!

jumping timing isn't all that bad in these vehicles, now if you had a honda or an Interference engine then jumping timing means a whole new top end! check the codes, change timing chain or belt (you didn't specify which you had there were 2 3.0 engines in the 89 taurii) SHO, or Vulcan? either way if you got no codes need new belt or chain whichever vehicle you have!

MAP sensor used on that car. Still disconnect the electrical connector for it on the firewall, passenger side and continue with test indicated by Jeff.

Jeff I sent you a PM (unrelated).

Problem solved. You were correct, no ground. Once I pulled the trim piece off that covered the CCRM I immediately saw that the wire that goes to the negative post of the battery had pulled out of its plug. Thanks for all the help everybody.
