Thanks, Ron. I was trying to figure out how much I have lowered mine. It turns out 2" in the front and 2 1/2" in the rear.

Could be a clogged filter sock on pump, bad pump, bad pulsater or rubber fuel iine on output of pump causing gas to dump back into the tank. Or like Padgett said plugged fuel filter.

Clogged filter ?

Thanks Ronnie. Copied your comments and added with the TSB for my records.

I agree with the above but rule out the fuel pressure regulator before dropping the tank. I had a fuel pump that went bad last fall. It turned out the pump was bad although it was still running. You can read about how I diagnosed it by clicking the link below:

It will let you know if it's going bad without looking at the gages. Usually the first thing you will notice when the sending unit going bad is an intermittent electrical error message pops up and quickly disappears. If you happen to have the CRT in Gages mode you will see a really high spike in the oil pressure when the error message appears if your watching for it. If the spike in pressure is present for a certain amount of time a code B132 will be set in diagnostics. Otherwise no code is set. That can make it hard for new Reatta owners to figure out what is causing the intermittent error message.

I deleted the funky tables in the above post. After a communication with Ryan at GM Tuners/Sinister Performance, the mystery is solved as in, the later raw files are for two different PCM's which are incompatible. It still didn't explain why I couldn't at least view the files correctly with the matching datastream, but no matter at this point. He sent me one of each file for the early and late Series I supercharged, which I can view, modify and save, plus it makes sense. I still may have him do a custom tune for me as well and pay for it. He has been extremely helpful over more than a decade and a half, most of it gratis. It just reinforces the old axiom that a little knowledge is a dangerous thing🙂

Would someone be so kind as to measure the distance for the ground to the bottom of the heel well in the center front and back wheels , Please. My '89 with GoodYear Assurrance All-Season 215 65 R 15 w/ 32 psi is as follows: Front 28 13/32"; Back 29 29/32". Measurement taken from floor to dead-center of the wheel, but with the tire and wheel still on the car - meaning not dead center of the wheel well taht otherwise could be achieved with the tire and wheel off the vehicle. Hope this helps.

Hope you have it fixed. But here is my "soap box" speech. One has to remember that all the Reattas are now at least 31 years old. One has to have known good working back up parts. They would be [but not limited to] MAF Sensor, Ignition Module/Coil Pack, Oxygen Sensor, Crank Sensor. Combined cost for those parts used MAF Sensor, Ignition Module/Coil Pack, and new crank sensor, oxygen sensor is less then $200.00. Far less then a tow charge, diagnostic charge, repair charge and loss of confidence in your Reatta. A number of us have been "helping" for 15 years or more and we know that these are the parts that fail. Please everyone consider getting extra parts, it's called investing in yourself.

Well, on my way to work this morning driving my reatta, whatever this thing is came off the back of a truck and rolled into my lane hitting the side of my reatta . Damaged the passenger side fender behind the wheel.
