P0171 is a lean condition. Most likely cause is a restricted fuel filter.

My 95 buick lasabre just clik and don't crank we replace battery and started

If it just clicks make sure the engine isn't locked up by turning it by hand. If it turns freely it is possible that you have a defective starter motor provided all your connections to the starter and battery are clean and making good contact.

Code po 171 system lean on bank one what would cause this and what would the solution be on a 2002 buick lasabre

DTC P0171 and Po174 indicate air/fuel ratio is correcting rich for an overly lean condition. You could have several things causing this 1. fuel system malfuntion 2. EGR system malfunction 3. Air intake vacuum leak 4. Engine oil level to high 5. Incorrect cam timing 6. Restricted air cleaner 7. Faulty PCV system 8. Excessive internal engine wear.
Sorry I could not be more specific. Check for the easy things in this list. Most of the time one of the o2 sensors in bank one has failed and not reading correctly. Same on the 02 Lesabre.
