Hi, my remote start would not work, check engine light on.  I disconnected battery cable, let it sit a while, re-connected battery cable.  Started car, no engine light. Put new battery in remote.  Remote start does not work.  Check engine light does not come on.

 

Any  idea why remote start will not work?  Would like some ideas before I go to a dealer.  Possibly some kind of emissions sensor or a fuse?  Can NAPA check the code if there is not a check engine light on?  Thanks

Code is still present. Remote will not work until it is cleared by problem being fixed.

 

Safety feature.

Are you sure the remote start is non functional? Mine would not work because of a check engine light. So I fixed that, and it still would not remote start.

 

Turns out that I needed to read the owners manual.

 

I did not know that I had to press the door lock button first, and then hold the remote start button to get it to .... remote start.

1.  CEL is now off because I reset the system by disconnecting the battery for 15 minuets.  But problem could still exist.  I don’t want a $400 plus bill for the dealer to replace the sensor which will get me about 1/2 mile per/g  with a little more efficient burn.

 

2. would be nice to over-ride the issue;but how do you decide the issue?  Thus the NAPA code reader.  Will it work with the CEL off??

 

3.I have read the manual at least 3 times.  I have also done internet search’s.  Yes cas cap is on as it doesn’t have one,  maybe something to do with flapper.  Maybe wire to hood latch,  and maybe other issue.

 

Going to to NAPA.  Hoping they can identify the problem.

Until you pull the code you are just throwing guesses into the wind. As long as the CEL is stored in the ECM and the issue is not fixed and the ECM self-clears the code the remote start wont work. If you clear the CEL all it is gonna do is work for a bit, then once the CEL triggers again it will lock out the remote start.

 

Start with the basics, get the truck scanned and get the code then go from there.

You could buy an OBD2 code reader on Amazon, and reset the codes every so often. Not ideal, but it may fix the problem.

 

Clearing the codes with a scanner takes about 15 seconds.

 

The code reader costs $10.

      BAK MX4 EZ-Lift Install and Review

      By parthery · Posted

      I've been eyeing an upgrade to my tonneau cover for a bit now.  Intrigued by the BAK MX4 EZ-Lift with the torsion spring and went for the upgrade.  Thoughts and musings during unpacking, install and a few days of usage.   Once my order went into Realtruck, it took about 4 days to ship.  Unfortunately, FedEx Ground destroyed the box and contents and it was unusable upon receipt.  To Realtruck's credit, one email with pictures and an RMA was sent to me to send the first one back, and another unit was shipped out.  It arrived 3 days later, unscathed.   I opened the box and it looked like every other BAK MX4.   Biggest differences are the rails and retaining clamps, and of course the spring attached to the cover itself.     NOTE - if you are upgrading from a MX4 to the EZ-Lift, you will have to replace the rails.  The EZ-Lift rails have a notch cut in them to allow the new style retaining clamps to fit properly.  The new retaining clamps also have 2 knobs/carriage bolts and there are two tracks underneath the front panel. The strap clips are mildly different (more like the Undercover Flex clamps) in that the screws go in from the underside.  Personally I prefer these over the BAK clamps that use the nutserts that are a nuisance to install.  The remainder of the parts in the box (drain tubes, rail clamps, and bumper pads) are standard issue BAK.     I did not replace my front bed seal at the time because it seemed to be in decent shape.   BAK recommends shims on the GM trucks unless you place the clamps on the flanges about 1/3 of the way in from both the front and rear of the bed.  I shimmed the front and the middle, and initially placed the clamps equidistant.  This also turned out to be a mistake, because when I set the cover in place, the new style retaining clamps wouldn't clear the front clamp.   New style clamp inserted in the track:     And the issue which occurred because the front rail clamp was too far forward:     Once I removed the shim from the front of the bed, and slid the clamp back to the front flange, everything cleared fine.     The cover set on the rails without issue and I installed the strap clamps.  After I completed my adjustments, I pulled the pin to activate the torsion spring.  Mistake #3 on my part.  PULL THE PIN AS THE VERY VERY VERY LAST STEP!  The reason is, once you pull the pin, the torsion spring is activated.  If you have to loosen the front clamps and adjust the cover, the front panel will - by virtue of the spring, refuse to lay down.  The only way to get it to lay down so you can reinstall and tighten the clamps is to fully open the panel against the back of the cab, which will then allow the front panel of the cover to lay down and be tightened.  Not a big deal unless you haven't installed the foam pads yet (typically the last step) because minus the foam pads, you will need to place something between the frame of the cover and the back window so it doesn't get scratched.  The next time I install one I will install the foam pads before I pull the pin and activate the spring.   After using it for a few days:   The spring assist is great.  You literally can open it with one hand.  My shoulders aren't getting any younger and this was part of my motivation to swap out. The second panel latches and unlatches itself as you open and close the cover.  Neat in concept, however it took me a minute to get used to closing the cover and not hearing the "latching" sound that would tell me it was locked in place. The paddle handles are a huge upgrade and I wouldn't be surprised to see them become the standard across the Realtruck line.  They effectively eliminate the concern that a thief could coat hanger the cover open and get to the contents in the bed. I'm not sure why the very front panel on my cover has a different finish from the other 3 panels.  I have a request into Realtruck to find out if mine was not manufactured properly or if it was by design.   All in all I'm pleased.  Same level of protection, looks good, keeps stuff mostly dry (they all leak around the tailgate) and easy to install.

      PF63 Oil Filters Going Away?

      By Chuck FB · Posted

      Same here, first I bought a few filters to get me going right after I bought my truck to do some short distance initial oil changes, then realized I could buy a case lot for less as they drop the price if filters or trans oil etc is bought by the un opened case lot as well as the discount for buying the vehicle there. So I have filters for a while but its good to know going forward, knowing to expect it to be a different part number and looking filter at the dealer and not be confused over it and think they are handing me the wrong part.
