Took this from one of the PTDIY boards...dunno if it'll help or not.
I have a 2003 PT with 8k miles on it, which I had serviced today because the engine light came on and fuel gauge needle dropped to empty and then back to the correct level, indicating about half a tank. The dealer indicated that the problem was corrected with TSB 18-029-02, (Software download to correct an issue pertaining to hard starts or long-crank to start the car.) which updated the controller. After the repair I was about one mile from the dealership when the engine light came back on and fuel gauge needle dropped to totally empty, then back to half-full, to empty, and finally to one-eighth tank. The technicians at the service center are clueless thus far. I suspect that after updating the software the technician did not run the diagnostics again to make sure there were no further issues and that the codes were cleared. The fault codes were PO462, PO1604 and P1681. Other than this issue, it's a fabulous car. - Rob, from USA.
It sounds like a simple intermittent circuit in the sending unit. It's a mechanical gauge wired to the sending unit in the tank. The dealer may be searching for a computer problem when it's only a mechanical defect.
P0462 Fuel Level Sending Unit Volts Too Low - Fuel level sensor input below acceptable voltage.
P1604 PCM Internal Dual Port Ram Read/Write Integrity Failure - Dual port RAM read/write error.
P1681 No I/P Cluster CCD/J1850 Messages Received - No CCD/J1850 messages received from the cluster control module.
Follow up from owner - I called the dealer on Friday, intent on taking the car to another dealership on Tuesday, since the first shop had the car for three days. When I arrived, the service advisor told me they had discovered that the problem was a faulty headlamp wiring harness. Since the repair, I have started it seven times while running errands and found no repeat of the MIL or gas gauge needle issue.

Victor you mite want to get it checked at the stealer ship. Just a few weeks ago my whole electrical system got fryed. I was told it was due to the green cable that runs to the starter. I had to pay $1,000 for a new battery, starter, two different wire harness plus $200 for towing. Bro so you mite want to get it looked at soon.
