Defective New Crank Location Sensor

[BryanEstep]

I bought a brand new CLS and it plugged up to everything just fine but when i tried to crank the truck all it did was crank but never started. Tore the engine apart and "reset" the timing" and still nothing, and finally we did it again, checked the timing, and put the old CLS on and it started and ran. Tore it apart three times and it LITERALLY took all day.

Can someone tell me why the new one might not work? Website said it would and everything. I have a 1994 Ford Ranger 2.3L 5 Speed Splash, but not really anymore bc regular bed now bc the old one got crushed before i got the truck so i changed beds.

If the old one works and the new one does not, you most likely got a defective part. Return the new one and put the old one back in since it works.

CKP(crank position) sensor is located behind the timing belt just above Crank shafts timing belt gear, it is a Hall Effect sensor
1995 and up 2.3l/2.5l used a different CKP sensor, located on front cover, VR sensor

Yes, if the new sensor doesn't work and old one did then new one is bad

"New" used to mean "tested and working"
"New" now means "You test it and if it doesn't work we will replace it"

Labor is too expensive now to have a Quality Control Department.
Ford Parts are usually tested which is why they are silly expensive compared to 3rd party parts.
Worth it to Ford to use tested parts because after assembly they want to send these vehicles down the road, not troubleshoot them.

For most 3rd party parts it is worth saving the money but things like fuel pumps that are hard to change, labor wise, its almost better to used Tested parts, and bite the bullet on cost, but just my opinion

shipping price would have been terrible so i just kept it... but i still wanna know why it didnt work at all.

Also, the reason i got it is because my dad and my uncle, who was a mechanic for a long time,believed the problem was that. But im pretty sure if a sensor is bad it will just break down. I still think we dont have the timing dead on. the amount of blow off when slowing down out of 4th into fifth makes it sound like a diesel with a blow off valve. And I get no power in 4th gear. some friends have said it might be rings and if thats the case i'll probably just buy a new engine and or vehicle. Why both maybe? Personal reasons.

Do a compression test, that will tell you if cam timing is correct and ring condition

Remove 1 spark plug from each cylinder, so you get good crank speed
Test each cylinder DRY then add a teaspoon of oil via spark plug hole and test again, WET test

1994 2.3l Lima had compression ratio of 9.4:1 so using the 18psi multiplier you should expect about 170psi compression in each cylinder, thats a new engine, so 160-165psi would be OK.

If DRY test was 140psi, and WET test was 155psi then rings would be the issue
WET test will ALWAYS be higher than DRY, but should be 10psi or less

If overall, 4 cylinders, show under 145psi then cam timing is off
The Cam Gear and AUX(oil pump) Gear often have BOTH timing marks, the triangle and the diamond
Triangle mark is for Cam alignment, about 4:00
Diamond for AUX alignment, 12:00
Crank gear alignment is woodruff key at 12:00 BUT.......12:00 to ENGINE not vehicle, 2.3l sit at an angle in the vehicle, so woodruff key would NOT BE pointed straight up to the hood, it would be at same angle as the engine.

If you live near Northeast Georgia I'll just pay you to do it lol. thanks for the info
