P3190 is not very informative, but it says the engine failed to fire up when it should have. In the second generation a generous amount of cranking time is allowed so the engine was definitely not getting fuel or possibly air. The Prius throws brake warnings like rice at a wedding, and the VSC will not operate if the engine is sick.































First what I can tell you - this is a problem in the engine operation, not in the hybrid system. If it were a conventional car you would experience it stalling but it would restart. I recommend a professional for this, though, and the dealer would be a good choice. It takes a Toyota Hand Held Tester to make the second generation engine run when the tech wants it to.































My hunch is the problem is in fuel delivery and the fix will be a new fuel tank. The fuel pump, pressure regulator, and filter are integral to the tank. Contaminated gas is the prime suspect. But the cost of the fuel tank makes guessing a very bad thing.































With this identifiable problem I suspect the intermittent "ready" is also the result of the fuel issue.































EDIT - if the fuel tank is condemned a tank from a wrecking yard would be a decent gamble. The labor is fairly small compared to the price of a new tank and the going price at wrecking yards is $150-$200.
