then check to see if there is play in the rods where they connect to the crankshaft

- Thu Oct 23, 2008 12:44 am #75617 can you spin over the motor. A spun bearing will not stop the car from starting. I know, My LS still starts and I have 1 or more spun bearings.

a spun bearing will not keep your motor from turning over.
take the spark plugs out, put it in neutral, and turn the crank counter clockwise with a 17mm socket.
the rod may make a knock as it turns from play on the crank.

- Thu Oct 23, 2008 10:27 pm #75728 so i took not a 17 but a 19mm and turn the crank, and all the pistons move up and down just fine. could i still have a spun bearing? it quit on me while driving and wouldnt start. like a the flywheel broke or something. any more suggestions. i dont want to put it all back to gether and it wont start. that would make me quite.

- Fri Oct 24, 2008 4:22 am #75790 a little late now, but to check fuel, put your ear by the rear seat & listen for the pump whine. Pull an injector or 2 and see if they were spraying while you were cranking the engine.

To check spark, pull a plug out and touch the end near a valve cover bolt. Then try to start the car. You should see an arc if you're getting spark.

Compression, you'll need a tester to get accurate #'s. but you can take the plugs out except for one cyl at a time and crank the motor by hand. if it is hard to crank, then you have compression in that cyl. :thumb:
