More fun with the XTC.

Had some code problems so I thought I'd try and clear it up today. I cleared the codes and installed a new MAP and TPS sensor. Was getting code 23 and 34. Fired it up and the SES light came on in ess than a minute. Code 33????? Then I found that I forgot to hook up the vac line to the MAP - DOH! Cleared the codes, fired it up and after 3 minutes I get code 23. So it is either the MAT or the Mixture Control Solenoid. I am guessing but based on the amount of fuel coming from the injector at idle, I am going with the Mixture Control Solenoid first. I do not have a clue where it's located but I will find it.

Check this out - I almost fell over when I found this. New TPS


Wow - Page 3 ownage too!

Now thats funny right there. "Made in U.S.A" or "Made in OOO-sah - province of China".

The box says "Wells" - and I have never heard of them. It's probably just the case that is made here - then shipped off to china for assembly. Seems to have sured my TPS error code though - at least for now.

Thursday Night!

Was getting a code 23 so I replaced the MAT sensor - no more codes. Also installed a coolant temp switch and temp sensor. To recap, I replaced:

The TPS, MAP, MAT, Temp Sensor, Coolant Temp switch (fan). I was able to rebuild the dash and installed a tach and temp/fuel gauge and replaced the speedo with working trip ODO - transplanted the original Odometer, replaced the printed circuit sheet on the back and replaced / checked all the dash bulbs. We now have everything in the dash working, no codes, a wroking temp gauge, a working Tach and a working OP gauge. Only cost about 100.00 in parts and sensors. Made sure that the fan switch worked - I let the car heat up and at 220 the fan kicks on the car cools to 190, the fan shuts off.

We got the rest of the car buttoned up and took it for a little test (60 miles) drive and never got hot enough to kick the fan on. My home alignment works great - no tire squealing, no pulling, no darting, etc. I'm still going to take it to the alignment shop to get her as close to perfect as possible. She runs great and drives so much better with all new poly all the way around, new shocks up front and new struts in the back. I love it when all that hard work pays off.

I love it when a plan comes together.

Well I have been out of town for the last 3 weeks - no time to work on the XTC till this evening. Last weekend, I took it to the gas station to fill it up (only filled it twice). This time, I heard a splashing noise under the car when the pump shut off. I looked underneath and there was gas dripping off the tank. I got it home, jacked it up but I could not tell exactly where it was leaking. I tightened all the hose clamps but then ran out of time. It looked like it was coming from the top of the tank.

This evening, I had my boy pour some gas out of a can in the car while I watched under the car. Sure enough, gas was leaking from the top of the tank. I pulled the tank out and found that the locking ring for the pump was offset. When I pulled the pump out, I found that the O Ring seal was goofed up. Not sure if the PO replaced the pump or not but the tank had been out of the car sometime in it's past.

So now I just have to decide if it is worth getting a new pump while it is apart. Anyone have any suggestions on brand? I'll be searching the web tonight! More later.

I would throw a new pump in there if it was me. Get a factory replacement/AC Delco pump.

Installed a new pump, screen and fuel filter today. Back up and running now. Found something interesting. The fuel filter was installed backwards. Maybe it's me but with the new pump and filter, it seems to run a lot better. Of course it would not be a Fiero if I did not run into "other" issues.

As I had the car up in the air, I noticed a coolant leak up front. Found the overflow tank to be - well "overflowing". I removed the rad cap and found the gasket to be messed up. Most likely allowing coolant to leak by and drain into the overflow tank while the back end was up in the air. I picked up a new cap and am hoping the car will run a little cooler now.

When I drove it to the parts store to get the new cap, I could hear a "squealing" coming from the engine compartment. My first thought was alternator. Some checking with a stethascope shows that it is the belt slipping. Back to the parts store for a new belt now. It never ends.

Edit to add: Forgot to add, before I reinstalled the tank, I put a half a gallon of gas in it and turned it upside down to check the seal. New seal works fine but I found that the "return" line leaks where it goes through the monuting plate - not much but it did get "wet" with gas. I'll be hunting for another unit to replace it with.

Hey Pat. If you find any parts you need at AutoZone, let me know. I got a connection here at home. You are still more than welcome to my 88 for research or spares. Looks like I may end up keeping/building it. It will be down the road though. I will be replacing the pump with a higher capacity one, so the stock one here is available, as well as any duke parts. You know my number...
