HelloThe Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

Why would you not diagnose & repair, if necessary, theABS/Trac issue,seeing as how your very though on everthing else.Resolve the Code related issue firstChange the Power Steering Fluid & add some LubgardAdditive,no other product to any thing on vehicle exceptLubgard in the trans ,which along with the P/S should be changed every 3 years Your noise is the transaxle or alternator,unless you have some ABS Pump or HCU issues there

It is possible that the tumblers in the ignition need lubrication. I had this problem with a boat ignition. Spray a small amount of break free, or WD 40 or graphite penetrating oil into the slot and slowly work the key gently into it. A drop of oil in the slots of the key won't hurt.

Usually a sign of a leaking head gasket or intake gasket, or other engine problem.

There is no access to open the hood from the grille

Usually this is just a bad wheel bearing assy. Which comes with the speed sensor.. But double check the wiring to the sensor sometimes they can rub against the axle shaft if they come loose and get cut in two..

There is nobody that can tell you what is wrong without first DIAGNOSING the problem with your car. There are many things that can make the engine stall. There are also many things that can make and engine "jump" or "surge". All that can be done without proper diagnosis is GUESS. Guessing will most likely cost you a lot more money than having the problem diagnosed by a professional.

they had a problem with the fuel pressure regulator and when cranking slow the intake manifold blows up there is a recall on some years

That plastic tube/elbow is a very common issue with these vehicles. To replace it you have to remove that whole bracket which houses the tensioner.

Have you checked the rear brakes? They can cause shaking just like the front can.
