For the past 2 or 3 weeks I have been leaking coolant, Just did the water pump ( definitely shot) and there is a slight drip from around it but not enough to leak the way it is and it also only drips above 2k rpms. I have to fill the reservoir up every 3 days or so AFTER the water pump was done. Today when I had the rear jacked up looking for the leak I left it up for a while and come back to see a ton of my coolant leaked out of the reservoir cap and onto the floor . I took it out of the garage and the temp shot up, it drained from the goddamn engine into the reservoir. The little paper seal on the cap is shot and the cap itself barely stays on. My entire commute is up and down hill. Could that be the main problem?

you MUST fix the leak around the water pump, it not only has a hole to leak from, but also a hole to suck in AIR. the reservoir CAP is not the problem
Not Sure if its the pump or something else around there, I stuck my hand under the pump after I killed the engine and felt nothing, Anything in front of the pump to leak?
Sounds to me like at least part of your problem (with coolant spewing out of your reservoir) is perhaps having a vented rad cap. Fieros require a non-vented rad cap.
Lots of threads about this, including the recent discussion HERE.
Regarding your water pump leak, you might at least tell us which engine you have.

V6 1988 GT , I will have to check the rad cap as I did not change it.
OK heres an update: Pulled it into the garage today to look around the timing cover for the leak and took a look in the front too. I do in fact have a VENTED radiator cap, So I will be changing that tomorrow .

Yes. Plastic cap on overflow tank is not you problem. Gasket does little or nothing. (New caps are easy to get for many auto parts places. Dorman, Part Number: 82590 )

Yup. Wrong Radiator Cap and Iffy parts on engine is... Anyplace can leak air in w/o leaking coolant out is big issue, especially have wrong rad cap.
But note that if you have problem on the radiator, like tube problems for overflow tank, can fake an air leak at engine when you open Tstat Cover to look. Radiator w/ iffy tube will have air and will "suck down" Tstat housing when Tstat cover is off.

Know what, My 87 with 3800SC, I jacked up the rear end of the car, and I Also have coolant running out of the overflow ! And I HAVE a NEW "Correct" Radiator CAP !
