Megasquirt Issue or Something Else?
 

I purchased a car from the previous owner knowing that the car wouldn't start. The previous owner said that the car would start on and off until he thinks the MS shorted out and now the car will turn but won't fire. In addition to that, there are some strange things happening when I try to turn on the car:

The following video was shot with F/P and GND connected in the diagnostics box.


1. The MSPNP light that I originally said comes up isn't on when I try to start the car but DID come on AFTER I turned the key to off
2. The sound of what I think is the fuel injectors still shooting happened AFTER I turned the key to off and removed the key @ the 1:00 mark which is why I ran out the car to the engine bay again. You can CLEARLY hear some type of ticking.
3. @ the 1:30 mark, you can see the MSPNP light up but only the very bottom of the first P. Maybe there is a short with the MSPNP and it is the problem?

To add to that, Braineack has been trying to work with me in getting the computer hooked up to the MS so we can troubleshoot from there:

I followed the instructions documented on the MS Serial Setup (Megasquirt Serial Setup)

Device Manager shows that my USB-Serial is showing up:

I then connected it to the MS and turned the key to "Start". Ran the 'Portcheck.exe' program and nothing was identified:

I then tried to start the car and of course it didn't fire. Removed the key and then saw the MS light up with the usual "clicking". Decided to execute the Portcheck again:

Quickly opened up TS and opened a new project and hit 'Detect' and it actually found the MS:

Tried to move forward and then ran into this problem and didn't know what to do from here:

The problems are inconsistent. When I tried to hook back up to the MS, it wasn't identify or detecting it.

I'm at a lost of where to even start.

your firmware is corrupted.



You can keep this to your first post...it's all related, especially the part where I told you to use port checker and that your firmware might be corrupted...
