1992 buick Lesabre 3.8 has code 17

SOURCE: I have a 2000 buick lesabre. The fix engine soon

It NEVER was the camshaft sensor! Unless, you've removed the engine lately, which I doubt.
RUN to Advance Auto Parts and buy a can of "SeaFoam" and add to your gas tank per instructions...drive at least 100 miles and the problem should go away...IF it doesn't you'll have to replace the O2 sensors in the exhaust system...Any good mechanic should be able to do this for much less $$ than the dealership DO NOT go to the dealer for repairs!
Good Luck

Check and make sure your battery cables are clean and tight. You may want to check your ground wires inside the car, under the carpet. I had a bad ground under there.

i had that problem too.......COIL MODULE IS BAD NOT AN IDEAL JUNK YARD PART..I TRIED 1 AND IT LASTED A YEAR....NP $300.00

From what I get,you have a battery (12.31 Voltage Drop) all the time
No way all the fusable links are out of system
That is kind of extreme to cut them

Go to 20AMP first, and put the meter back in series,as your were.
If you get anything over 30 Mili Amp ,and it doesn't time out after 10 min,you found the issue.
The fuses out ,should have killed that.

Hi,

The steps I'm going to outline are the same as we use in my shop for hesitation, sag and stumble.

All of the tools required can be borrowed from AutoZone at NO COST!

Sensors:

The sensors can be checked with an OBD-II code scanner borrowed from AutoZone. Pay special attention to an TP (Throttle Position) warnings. The sensor can be manually checked for binding or sticking.
Check the Heated Oxygen Sensor (HO2S) found near the firewall and screwed into the exhaust manifold for signs of corrosion on the threads. That will cause a faulty ground.


Fuel System:

• Check the fuel pressure with that fuel pressure gauge from AutoZone. You reading should be 40-45 PSI and holding steady.
• Contaminated fuel is a constant problem and if the pressure does not hold steady, replace the fuel filter.

Additional Checks:

• Make certain that the engine thermostat is functioning and is the correct temperature.
• Make certain that the alternator voltage output is not less than 9 volts nor more than 17 volts.

Here's a little general information that will assist you in comprehending the readouts from the code scanner. This is simply for your edification. You may be aware of all this but we've never done business before and all assumptions are off the table.

For an engine - make that any engine and irrespective of manufacturer - to run, you need three things to happen inside the engine, compression, fuel and ignition, without any one of these components the engine will not run.

• Compression - Engine compression caused by crankshaft rotation and pistons moving up and down inside the engine block. If the timing belt or timing chain fails it will cause the camshaft to become out of correlation with the crankshaft or allow the camshaft to stop rotating. Either of these conditions will cause the engine to lose compression and sometimes cause internal engine damage.
• Fuel Delivery System - The fuel system includes: fuel pump, fuel injectors, pressure regulator, fuel filter and pressure lines. This system is used to supply fuel under pressure to the fuel injection system, the lack of fuel pressure or volume will cause the fuel delivery system to fail and the engine to stall or not start.
• Ignition Spark Delivery System - The ignition system components include: spark plugs, spark plug wires, distributor (if applicable), crankshaft angle sensor, camshaft angle sensor, ignition coil, ignition module, knock sensor and PCM (powertrain control module). The engine relies on the ignition spark to be delivered to the combustion camber at the correct time. If the ignition spark stops or is delivered at the wrong time the engine will not run or run poorly.

If Your Engine Cranks but Does Not Start Follow this Troubleshooting Guide (This doesn't necessarily pertain to you but it's useful to know)

Most vehicles operate by the same principle; basic troubleshooting procedures apply to most cars.

• Step 1: Anytime you have a problem with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, Air Bag) inspect all fuses using a test light and check the under hood power distribution center and under dash fuse panels. If all fuses test okay continue to the next step.
• Step 2: To check for problems with electronically controlled components such as an engine, transmission, ABS brake, or SRS (supplemental restraint system, Air Bag) and the fuses test okay a trouble code scan is needed to identify any system trouble. Use a simple scanner tool to retrieve trouble codes and see if they relate to the specific problem, like a crank angle sensor failure code. If the trouble code present does not pertain to the immediate problem like an EVAP code ignore it until a later time, after the car is running.

The reason you should repair non-related codes after the engine is running is because sometimes false codes can be triggered by the engine not running. Once the engine is running again the code present might cycle and turn itself off. You might say "if the engine doesn't run shouldn't it have a trouble code?" Sometimes conditions occur that will not be detected by the computer, example: if the fuel pump fails the computer cannot detect the failure, so the engine doesn't start and the computer thinks everything is okay with no codes. If no trouble codes are present proceed to the next step.
