After I have replaced the spark plugs with new Mazda plugs, top up the battery electrolite level and done the 20 brake proc, it still takes 4 sec's to crank and only then she fires up.
I must say she idle's 100% and rev and acc to 9000rpm like a rotary should.
I have picked up o(attached foto's) that between my air box and a sensor on the pipe (going to the intake) there is a small hole which the previous owner have cover up with tape.
Can someone tell me is their a missing sensor? Any comments

 

Hmm.

Small hole? you mean the tape is covering a small hole at that area ? (between the MAF and Air box)

If thats the case ... hmm ... I wonder what the previous owner did to the car since there is no reason for anybody to drill a hole at that area ...

Takes 4 seconds to crank? not good.

Even my old dead engine starts in less than 2 seconds.

 

there should be no hole there.

 

Yeah but I dont think that would effect the start up. If it is seal it. Have your starter checked at autozone or checker for free. If its bad you can get one at autozone for like $100 bucks.

 

I belive the motor (Compression) is fine, 52 000 km on the clock and the car is still in immaculate cond.
Next step I think will to do a battery load test and then to test the starter.
The hole is a 4mm in dia.
Thanks for the advice
