Neutral safety switch

Sorry for the delay. It appears this post was never confirmed after posting which means we didn't see it posted until you updated it. Sorry for the confusion.

As for this issue, there are no adjustments for what is called the transmission range sensor.

Basically, what we have to do is use the special tool that is shown below to align the TRS properly and then it will recognize the park position.

However, if you have already tried to adjust it then it may be damaged and require replacement.

So, I would get the tool which is available at most any parts store or online and try to align it properly and then see if it works. If not, I suspect you are going to have to replace it.

Let me know if you have questions. Thanks

So, the starter turns? If the starter turns but the engine doesn't fire, then you are correct that the TRS is allowing the starter turn.

I thought it was a no crank no start. So, if the engine is cranking and not starting and this started after the fuel filter change, we need to check the fuel pressure when this is doing it to find out if the pressure is low.

Let's start with this and go from there.

If the battery is drained to the point that it will not start with a jump start, then that will cause all sorts of electrical issues.

So, what I would recommend is replacing the battery and aligning the TRS before you do anything else. If you still have an issue after these then we can track that down. However, both these things need to be fixed first because they will make us think there are other issues.

Sounds good. If the TRS is not aligned or defective, then it will not allow the engine to crank. Basically, the PCM needs to see the proper voltage showing park or neutral. If it doesn't then it doesn't allow the starter to turn.

So, if the engine is cranking then the TRS is most likely not the issue.

Yes. It is possible. It is more important about the cranking amps of the battery. So, if the voltage were low but it passed the test and needs to be charged then I would just be careful if it is able to hold the charge.

So, if you put it back in the vehicle, I would just stop by the parts store again in a couple days and have them check it again and it should pass. If it needs to be charged again then you are going to have to replace it as it can't hold the charge.

We are going to have to get a new post started for this just because we have gone into a crank no start issue pretty deep and others are not going to find the solution for this under this topic.

Basically, we are here to help you, but you will help others in the future when you solve the issue.

So, I think we may have had two issues. I don't think you caused it with the fuel filter replacement, but it is possible. Basically, I think the pump has failed and needs to be replaced. We will prove this out on a new post but as long as there is power to the pump, and it is not coming on or building pressure then the pump is the issue. This is typical when you have to turn the key to build pressure and then it stops running.

I get it. Unfortunately, fuel pumps are not consistently failing so they will work flawlessly sometimes and then others they will cause these types of issues.

Thanks for getting a new post started but I am sure we will be able to figure this out.

Thanks
