Engine won't start... HELP!
My 1994 LS400 engine will not start. The engine turns over just fine and it sounds just like a normal start but nothing happens -- it just keeps turning. I checked each coil by hooking a spark plug to a new spark plug wire and grounding against the engine block, but I got no spark on either side when starting the engine. I took a spark plug out after trying to start a few times but the bottom didn't look wet and didn't really smell like gas at all... any ideas? Is my engine computer bad or something? Would an ODB code help out in this situation? Thanks in advance for your help!

Thank-you very much for the suggestion. I will try and get that information for you. In the meantime, is the crankshaft position sensor easy to get at? How do I locate it? Maybe I can clean it off or something? Thanks!

The check engine light was on when I had the key in the ON position. I tried to jumper E1 and TE1 but the check engine light just kept flashing -- there were no pauses at all... the car was in neutral and I had all accessories off. The battery was disconnected for a long while before I tried this... do I need to try and start the car or something to get the error codes set or does that mean that there are no errors? Again, my car won't start, so I don't know if the check engine light stays on after the car has started. The spark plug wires I was using to test with were brand new.

After my last post I replaced all spark plug wires in my car -- that did not fix my issue. When I brought it to my local mechanic, he narrowed it down to the cranshaft position sensor. Apparently, according to him, a critter had eaten through the CPS harness, and so to fix it, he repaired the harness.
