hard starting

Just a little bit of info on starting the earlier Ravs if the injectors are getting a bit tired and are leaking a bit of fuel.

If you turn the key to ON, the fuel pump is switched on to boost the fuel pressure. If the injectors are leaking, it could give too rich a mixture to start and you end up flooding the engine.

My advice is to only turn to ACC, but then turn straight to START, do not turn to ON and leave it for a few seconds before turning to START. This might help on those cold winter starts, when sometimes the engine is a little reluctant to start.

This allows the engine to start taking in air and the fuel pressure will take a little time to rise, which means that the mixture for one rev or two might start weak due to the low fuel pressure, but then if it was heading for being too rich, there should be several of the cylinders that get the perfect mixture to fire.

The fuel pressure takes time to rise because of the volume of the fuel piping and filter, which needs extra fuel pumping in to raise the pressure. The metal pipe bits might not stretch much, but the rubber and plastic does a bit.

Hope this helps......happy cranking.

New cars are uneconomic to buy.
There is no such thing as uneconomic to repair, but it could become too dangerous to repair.
