Mazda Protege5 will not start

My qualifications are as follows.

Raise in my father’s heavy equipment shop.

Extensive training in industrial engine, Automobiles, Diesels trains, Diesel trucks and equipment.

Training is Steam boilers and locomotives.

Training in Gas and Turbine aircraft engines.

I have more but I will get boring LOL

I am presently working part time on agriculture equipment.

I am 79 years old and working in order to keep my weight where it should be. When the ranch manager found out why I was working for him he wanted to charge me for his weight control program. LOL

At any rate this Protege5 was towed in with a failed timing belt. The tensioner pully had broken the bolt and the timing had changed so the engine would not start.



The model of the vehicle is: Mazda Protege5 manufactured 10/02 with the 2.0 engine.



I was able to get the broken piece out and put new bolt in. So, I put the timing back with the old parts and rotated the engine by had to determine there was compression on all 4 cylinders.

I installed a timing belt kit.

I still have compression on all 4.

Now it will not start. It acts like the Ing timing is far advanced.

I have perforated the following to try and determine the problem.Removed the valve cover and varied the camshaft timing to be correct by the Mazda manual.

Removed all spark plugs and plugged them in to the coil wires so they would work I didn’t want to crank the engine without providing proper Ing grounding.

Hooked the scan tool up and spun the engine while watching the data and found the engine RPM to be 200 and the timing to be 10 degrees.

This indicate the crank position sensor to be working but the timing seemed stable to stable.



So, I unplugged the Camshaft position sensor and spun the engine again and still had 10 degrees indicated on the timing.



OK now my question to all of the experts and armatures here to verify my decision that that $179.00 Camshaft position sensor is bad.


Thanks to all of you for even enduring my dissertation.



By the way I am doing this work free of charge for one of the Interns working the ranch to finish her college degree.

Update

Here is a little more information.

I have good spark just not at the correct time.

I have 180 Lbs. plus on all 4 cylinders so came shaft timing must be correct.

New CPS did not help.

Any ideas?

Now I will let you all see if you can guess what I did wrong.



Here is a picture before I corrected the mistake.

Assuming, that is the camshaft timing alignment procedure for that exact engine, it should be I( intake cam ) to E (exhaust cam) not E to I

( some Mazda engines use timing marks at 12 o'clock, some at 5 & 7 o'clock )

 

Ya timing is off thats why it wont start. Thats why it sounds like a grinder when trying to turn it over.

Easiest way to remember is like what Grim said. I should be on the left because thats where the Intake manifold is and E is for Exhaust because thats the exhaust side.

The marks you painted should point at each other in a downward 45 degree down angle. The marks you havent painted will line up then timing is correct and car will start first click.

Should look like this:




My guess is whoever took the sprockets off, reinstalled them in the opposite order so marks were off.

 

Very good I was beginning there wasn’t anyone here that worked on these things.

The engine sounded normal the original time when I said the timing seemed to be advanced to far was a bad Camshaft sensor. The new one stopped all of that. But the engine still would not run.

I visually verified the camshaft timing buy TDC #1 and found # 4 to have both lobes in the proper position and #1 to be TD C exhaust with both valves open. This is normal this engine apparently has 4 to 6 degrees valve lap at TDC exhaust.

So with everything appearing to be correct I sat down with the manual again.

I then found just exactly what you have pointed out.

Wapwapwap the gears are made with both markings on them if you look close at the picture you can see the correct marking at the top of the gears. This was totally my error the gears are made that way as a manufacturing cost cut they only make on gear for both sides.

It now runs very well.

See attached picture.

Yaye!!! you got it running! good job. If you took the sprockets off and switched them around they would of lined up properly, but didnt need to cause you could just mark the other two that werent marked lol

 

Thanks for all the help.

This Mazda leaves from south Florida for Seattle Washington the third of next month.
