I got the car knowing it needed a new 5 speed. That was solved.
Before pulling motor the cooling fan would cycle on and off as should. Now it don't.
When motor was pulled the wire harness was removed off the ecm and pushed out the hole in firewall so no sensor was disconnected.
When testing the fan control switch do i bring the single wire to ground or positive. I am sure it is to ground but wanted to make sure first.

Now for the vacuum lines.
Their is a solid line along the firewall leading to the air cleaner box with rubber line that should connect it to the box.
On the box it is plugged and the solid line is open. What dose this connect to I can not find anything that matches is diameter.
The line on the back on the EGR solenoid is connected to nothing it has about a 12 inch line on it and it is plugged.
My 88 has a solid line it connects to and runs over to air cleaner area. On the 87 their is not solid line along firewall for it to connect to.

And on the 87 GT what speedo packages came with the car min has the 85 MPH.

Thanks Jeff

------------------
85 SE 2m4 2.4 L4 5 speed
87 GT 2.8 V6 5 speed Gold and Gray
88 Formula CJB T-Top Project i think its going to stay Formula

ProjectPb for all for paintball needs check this out

On the cooling fan wire, yes it's ground.

For the vacuum lines, hopefully someone with a V6 will chime in. In the meantime, here's a vcauum diagram:

RWDPLZ thanks i have that vacuum diagram and it dose not show the one coming off the back side of the EGR solenoid



this is the line connecting the air cleaner box




how can i check to see if this car is a factory GT is it a RPO code or in the Vin.

its in the VIN i found this site http://www.nytmare.org/fiero/vin/fierovin.htm and this matches me VIN 1G2PG119#HP2##### - 1987 Fiero GT

Dam some one swapped out the spedo so who know how many miles are on it on title is says " odometer disclose exempt by fed law "

The 5th character of the VIN tells you the model, so if it's a G then yes it's a GT. 10th character is the year, and H is 87. Being an 87, there should be stickers all over the car with the VIN on them, makes sure they all match the one on the dash, and the RPO sheet under the hood.

quote on it on title is says " odometer disclose exempt by fed law "

That means the mileage isn't accurate, probably because someone swapped out the speedometer. This is unfortunate, because swapping the odometer withe the mileage on it between speedometers is actually easy. If you want to know approximately how many miles are on it, I would run a carfax on that VIN, it will usually tell you.

The pic with the air cleaner housing missing, shows the AC Compressor Control relay unplugged.

The tube on the firewall: that was disconnected as part of a recall, and is just left open. Check this out:

The pic with the EGR solenoid: I THINK that's just a vent, but I'm not sure?

I seen that on the site i linked. It is good to know it is a real GT bad to know the mileage is wrong.

Yeah I know I took the pic as I was disconnecting everything so I can pull the motor when I did the tranny swap.
also good to know the one tube dose nothing and I will remove it. As for the EGR on my 88 their is a metal line on the firewall it connects to.

thanks

ALL V6 87s came with the 120mph speedo... so if yours has an 85, it was swapped out.

Anyone know of a free way to check vin for reported miles.
would be nice to know what this car has on it

I found where the loose vacuum line off the EGR solenoid goes. A solid line mounted on firewall.

Oh man thanks Project Pb. Finally got around to messing w/ an 88 formula I bought year and a half ago (covered and in a garage entire time since) and I had the exact same questions you had and very little luck with answers. I saw the large tube also and am glad to know the disconnection was a recall fix. Very many, many thanks for posting the solutions.

Now I think previous owner added an after-market cruise as it doesn't look factory installed w/ either mounting or wiring and it is electric powered instead of vacuum. I'm fairly sure Formula's are bare-boned and cruise possibly wasn't an even an option. The ignition module went out shortly after I bought it when I turned on the cruise. Since the cruise runs a wire to the tach wire coming from the ignition coil how possible is it that the cruise module caused this? I'm thinking of splicing a diode in the wire from tach wire to cruise module to keep the juice flowing one way. Is this reasonable?
