#30 of 32 Drove through water and then...
Jul 20, 2008 (9:32 am)
....my engine shut off. I was pushing through a few standing waters (about 6-8 inches deep after heavy rains) in my Toyota 4Runner and on the last one, my engine just shut off. The electrical system works fine it's just that the engine won't turn at all. Some info: the air filter was soaking wet, starter won't engage.
Any ideas what I screwed up here? Is my engine toast? Should I let it sit for a couple days (tow driver recommended that)? Is there a minor repair I can do on my own? I had 4 years of Automotive Repair training in high school so I know which way is up on a wrench.
ugh. but thanks

Figure out whether the problem is electrical, or mechanical.
Water doesn't compress, so if you sucked water into your cylinders, the engine will be locked and nothing will be able to turn the engine over. Pull out the spark plugs, and see what comes out (water, you are in trouble). Carefully stick a narrow air nozzle into the spark plug hole into the cylinder, and see what blows out when you open up the air to it. Check the oil dipstick, see if the level is higher than normal. Oil floats on water, so if water got into your crankcase, your oil level would be high. You could also try draining the oil to see what comes out.
Water in the cylinder yields broken connecting rods, and crankshafts.....in addition to the obvious rust ruining the bearings problem.
If the engine checks out mechanically, then get a volt meter on the base electricals. Check that you have +13 volts on the main power feed to the starter. Check to see if you have +13 volts on the fuse buss. Check then to see when you turn the key in the ignition, whether you have +volt feed to the starter solenoid.
