I have a 93 Buick Skylark GS 3300 Engine Series and my car is cranking but not firing. Diagnostic scan turned up a DTC42 code-spark timing error. The spark plugs are not firing. Replaced crankshaft sensor...

think a timing belt slippage or camshaft position sensor,
deffiantly something there to take a deeper look at.
double check the cams and their alighnment marks that they alighn with TDC if out of sync. nothing will fire right,the coil pack has no ides where anything is for some reason,good luck with this one,Gary

Car won't run

Yes it could be the things you mentioned, and also low fuel pressure.
Have you checked fuel pressure at the injectors with a gauge ?

DTC P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)
The crankshaft position sensor (CKP) and Camshaft position sensor (CMP) work in harmony to control the spark/fuel delivery and timing. They both consist of a reluctor, or tone, ring which passes over a magnetic sensor, which generates a voltage, indicating position.

The crankshaft sensor is part of the primary ignition system and functions as the "trigger". It detects the position of the crankshaft relays that information on to the PCM or the ignition module (depending on the vehicle) to control spark timing. The Camshaft position sensor detects the position of the camshafts and relays the information to the PCM. The PCM uses the CMP signal to identify the beginning of the injector sequence. What ties these two shafts and their sensors together is the timing belt or chain. The cam and crank should be precisely timed together. If the PCM detects that the Crank and Cam signals are out of time by a specific number of degrees, this P0016 code will set.

Symptoms of a P0016 will or may include:
Malfunction Indicator Lamp (MIL) illumination
The engine may run but with reduced performance
The engine may crank but not start
The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
The engine may start and run, but poorly

Causes may include:
Timing chain stretched, or timing belt skipped a tooth due to wear
Misalignment of timing belt/chain
Tone ring on crankshaft slipped/broken
Tone ring on camshaft slipped/broken
Bad crank sensor
Bad cam sensor
Damaged wiring to crank/cam sensor
Timing belt/chain tensioner damaged

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

I have changed the battery , alternator, spark plugs. fuel filter,coil packs, crankshaft sensor . tested the ignition module. and it still wont start. it turns over but just goes rrrrrrr and nothing ?

I am sorry you have already done all that work! You need to check the cam sensor magnet on the cam gear. You can remove the cam sensor which has 3 wires going to it and is mounted behind the belt near the waterpump. the magnet will sometimes break off its holder and that will keep the engine from starting as it can not sequence the fuel injectors. if the magnet is ok then you probably have a bad timing chain and gear. That series 3.8 buick engine has a camshaft gear which has an aluminum gear with PLASTIC teeth. Yes plastic teeth. The plastic becomes old and brittle and breaks off leaving you with an engine that wont start. Dont feel bad or dumb for replacing what you did as I have seen many TECHNICIANS who have done the same thing as I have worked for the G.M. dealer for years. I give you credit for doing what you could! Unfortunately you will probably have to replace the timing chain and gears. It is not a SUPER hard job but expierence in doing this type of repair is recommended. If you DO do it yourself, Make this one note. The 2 bolts holding the cam gear to the camshaft are TWO DIFFRENT LENGTHS! The longer one goes thru the cam sensor which is mounted on the face of the cam gear. Good luck! Scott
Please rate my answer good or bad - Thank you

Fuel Pump And injector. And will not turn over

This problem can be caused by many things. But, the ignition module is responsible for firing the spark plugs, then sending the spark signal to the PCM so the PCM can fire the injectors and run the pump. The module gets a signal from the camshaft position sensor. I just fixed this problem on a Saturn and it ended up being a bad EST wire from the module to the PCM. It can also be a bad module or a bad fuse on either system. Check all of the fuses under the hood and inside the car. The module can be removed and tested for free at Auto Zone.

1990 buick riviera,not firing,replaced ignition coil and ignition control module,still not firing,have redone all the grounds ,now what? no fire.

Crank sensor would be next. Also if it has an ecm #1228253 replace it as they give trouble, use 16198264 or newer number.

Changing a camshaft position sensor on a 90 riviera

3.8 engine?
Just look to the left of the water pump in on the timing chain cover.
You don't have to remove anything else. Take the one bolt attaching it and pull it out.Be gentle with the wiring.This should not take more than 15min.Have you changed the CRANK sensor.That's the one that should be changed at ever tune up and causes the most trouble.
Change it too.
