You can take one spark plug wire off and lay it against metal and see if there's spark.   Also when you turn the key to "on" do you hear the fuel pump in the tank run for a couple of seconds? If it doesn't prime when the key is turned, the car has to crank long enough for oil pressure to build up and that turns on the main switch to the fuel pump. But that's not 20-30 tries; it's more like 5 seconds or so to build up oil pressure for the switch to trip. Replies to this message: cbart_1 (Oct 18, 2007 6:52 pm)

Replying to: imidazol97 (Oct 18, 2007 4:34 pm) The engine does not turn over at all when the key is turned forward. It's as if there is no power going to the starter when I try to start the car. It does nothing. The starter is good I had it tested about a month ago. I really think it is the ignition switch, but I've never had this problem before so I'm not to for sure if that is the problem. Thanks for the reply.

Replying to: cbart_1 (Oct 18, 2007 3:12 pm) Have the battery cables been compltely removed and cleaned? The cables inside may have corrosion also. The most common problem is the double layer contact on the positive connection. Take them apart and remove corrosion. Brighten the contact area if you have a wire brush or sandpaper.   I didn't understand that your starter wasn't turning.   Check the connections at the starter for corrosion also.   Starters do fail. If you see a lot of oil drips from the oil pan bolts, the oil drops that accumulate over miles can get into the starter and cause contact problems.   If you do get under the car, use jack stands..., but tap the starter with something heavy like a ball peen hammer or heavy screwdriver handle to see if that improves the contacts.
#11 of 46 Won't crank by kenu Oct 27, 2007 (11:21 am)
I have a 1997 Buick Park Ave. It over heated and I added more fluid. The next day, I went to crank it over, and it started for a second and stopped. I discovered through online discussions that the intake gasket leaked into the pistons. It was hydrolocked. I have replaced the gaskets, put in new plugs, and a new starter. The fluid was cleaned out of the pistons. The car will turnover without the plugs in. the car will not crank over at all once I put the plugs back in. No plug wires are crossed. Battery cable connections were cleaned. Also, I checked the valves and each valve is opening and closing. Any ideas?

#13 of 46 1996 Buick Pk. Ave. Engine Problem by joshlin1932 Nov 03, 2007 (8:51 am)
I drove my 96 Buick Pk. Avenue into my garage, turned off the engine. When I came back later on to use the car again all it would do is click when I tried to engage the starter. I replaced the battery and had the same thing. I replaced the starter and had the same thing.   I removed the starter again to try to find the problem. I tried to turn the engine at the fly wheel and found that the engine was locked up. It will not turn over at all. Can you give me some ideas as to what could have happened and what I can do to correct it? Thanks Bunches!!!

Replying to: joshlin1932 (Nov 03, 2007 8:51 am) Take out all the spark plugs and see if it rotates and coolant comes out. It may be hydrolocked. I don't recall that year 3800 series II have some leaking intake manifold seals that can let coolant leak into a cylinder while the car is shut down and the system is hot and under pressure.   Had the car done any missing or skipping before shutting down? Has the coolant level needed refilling in the overflow reservoir?   If you find you were hydrolocked, change the oil immediately to get out the coolant. Do not drive it with coolant in the oil; it will corrode the bearings and you'll say bye-bye engine.

Replying to: imidazol97 (Nov 03, 2007 9:31 am) Thanks imidazol97.   I have taken out all of my spark plugs and no coolant was present. I put a socket and breakover and an 18 inch cheater pipe on the front nut on the crankshaft and the engine would not budge in either direction.   Yes, my water pump went out and the car heated up a little. The guage did not get into the red zone and the idiot light light did not come on, but the engine did steam some.   I replaced the water pump, changed the motor oil and filter and the transmission fluid and filter, and drove the car for about two weeks after that (about 1000 miles) and it worked O.K. except occasionally I could hear a noise that sort of sounded like tappets rattling except I did not think it was regular enough to be the tappets. Also, the sound was a lot more tinny sound that a tappet rattle. Replies to this message: imidazol97 (Nov 04, 2007 7:43 am) joshlin1932 (Nov 04, 2007 9:32 am)

Replying to: joshlin1932 (Nov 03, 2007 4:33 pm) oooops. You didn't mention the overheating session from before. But the gauge and light didn't make it seem too serious.   This is way about my pay grade and skill level. I might not be too serious and could be a disaster. Running right up to shut down and failing to restart sounds suspicious. Replies to this message: joshlin1932 (Nov 04, 2007 9:32 am)
