Car still won't start. Here are some results though:
1. Timing belt looks great. I removed the screws holding the cam cover on and could bend the cover enough to peek at it. I checked the condition of the belt and teeth, marked the section with Sharpie, turned the engine over slightly, and repeated until I could see that the entire belt was in good shape. No teeth missing. Phew.
2. Compression is good. Cyl 1 = 125 PSI, Cyl 2 = 105 PSI, Cyl 3 = 105 PSI, Cyl 4 = 110 PSI. Phew #2.
3. Spark looks ok. That's according to my spark tester thing, which goes inline between the wire boot and the plug, flashes consistently on each cylinder when turning the engine over. I'm not sure exactly how bright this spark should be, but it's bright enough to see in the dark, but not crazy bright.
Observation: I think I need a new valve cover. Spark plugs 2-4 all had oil on the threads. The firing end looked normal, but there was some oil present, not sure if that is due to fouling or oil dripping on them when I removed them. I'm probably going to replace them, even though they have low miles, when I re-do the valve cover gasket. Is it possible that this is causing my no-start? Maybe, if all the plugs are fouled out... Of course no local parts stores have the plugs and gasket in stock, so I'll have to wait a day or two to get them.
So, it appears that I've got compression, spark, fuel, and the timing is ok. What's next? Still no CEL light.
Also, all this time I've been assuming I have fuel. The fuel pump turns on when key is turned to run, and my SCT log shows Fuel Pressure PSI is about 45-50. Does that mean that I've got fuel actually going into the cylinders? Could my injectors have issues..? Anything else I could log on the SCT?
