You don't replace a relay
You go to a relay with a wirng
diagram, to start your testing
of the fuel pump circuit
Wiring diagram is needed, as your road map
Can't guess,have to see the circuit on paper,
understand it & pick a test point for a volt meter,
or other test equip
Never resolve installing parts
That is not a diagnostic strategy
& seldom works

The oil pump is not getting oil into the top of the engine quick enough on start up

I have a similar problem with a Mazda

Got over it by adding a can of STP Oil treatment to the engine

That coats the surfaces better than the standard oils and cuts down on the noise and the wear factor

I was thinking a broken motor mount until you said the clutch stopped working. Tranmission / clutch is my only thought now - sorry.

dont you love recalls they never seem to solve ****, and the problem with the timing chains is that it is really easy for the mechanic to cause unneeded damage to the engine. if the chain or belt snapped your in a world of hurt i would take it to another shop and get a second opion.

If I've understood your problem correctly.....when changing from 1st gear into second the box is giving a metal on metal crunching sound?
  • This would be the syncromesh ring which is not equalizing the speed correctly.
  • The problem usually happens when there is wear on the same part.
  • Check to make sure that the correct transmission fluid has been used in the box.
  • To alleviate the problem and delay the time when it will require attention, use the double de- clutch method of changing gears, especially when the transmission is cold.
  • The double de-clutch is carried out in the following way.
  1. When in gear and changing from 1st gear to 2nd, change into neutral and release the clutch and then depress again before selecting 2nd gear....It is not required to rev the engine in the neutral position when changing up....
  2. When changing down rev the engine when the shift lever is in neutral for each change.
You'll soon get the hang of it and stop the crunching sound, protecting the box at the same time....

Some cars have new system in the computer that lets the radio function for 20 minutes after the key is turned off and no doors have been opened, system should shut down immediately after you open a door
