The most common cause of long crank time is fuel pressure dropped while the engine was off. It should maintain pressure for days or weeks. A leaky fuel injector is the best suspect. To verify this, you can attach a fuel pressure gauge and watch what happens to the pressure when the car is sitting. Another potential clue can be found by turning the ignition switch to "run", wait a few seconds, turn it off, to "run" again, then crank the engine. Each time you turn the switch on the fuel pump will run for one second. Two seconds total is usually enough to build the pressure high enough for the engine to start. If dropping pressure is the cause, this procedure should help it start faster.
Given the code 340, it's more likely there's an intermittent problem with that sensor or its wiring and connectors. Start by checking for corrosion on the connector terminals.
I left the dealership in '99 so I'm not real familiar with your model, but in the '90s, a failure of either the camshaft position sensor or the crankshaft position sensor resulted in a no-start condition. There would be no spark and the fuel pump would not run during cranking, only for that initial one second, but that was enough to erroneously make it appear the pump was working.
If the timing belt jumped one tooth, a diagnostic fault code would be set related to "cam and crank sync", but the engine would still run. If it jumped two teeth, the Engine Computer would shut the engine down to protect the valves. At three teeth off, or if the timing belt broke, the pistons would hit and bend the open valves as they coasted to a stop.
On later models starting around 2001 or 2002, the engine would still run if the signal was lost from one of those two sensors while it was still running, but once stopped, it wouldn't restart with that one missing signal. My understanding is now they will start and run with one missing signal but I haven't run into that myself yet.
You don't have to go to the dealer for the charging system test. Most independent shops can handle that, and some do it for free. It only takes half a minute once the cables are hooked up.
