Hey guys, so it's been a long *** day because my dad was replacing a fuse on my car and saw that the stn fuse was missing and decided to plug one in. This is an obvious problem because megasquirt gen 2 do not want you to run this fuse. I went out and started the car and it ran for maybe a second and shut off immediately and after that would not start(only started because it was running off of left over fuel). I replaced the fuel relay not knowing the problem was in the ECU and the same thing happened where the pump did not prime or click and no start. I really need help because this is my daily and I have a very basic understanding of wiring and really need step by step help.

If anyone can assist that would be greatly appreciated!

 

The transistor that controls the fuel pump has blown. Just replace it and you're good to go.

 

Based on your statement that you have a very basic understanding of wiring, there's not much you can do on your own. Option #1 is to contact DIY support and ask them how you can fix it yourself and ask them how you can hotwire the fuel pump (warning: unsafe to do this in case of accident) as that's the problem, the ECU is not switching the fuel pump relay on. Option #2 is to find another vehicle for a few days to send it in for a repair. Option #3 is to find a shop that repairs laptops and phones and with a new transistor in hand, ask them to replace it for you.

 

Send it to DIYA for a fix. It was $75 for my repair of a similar issue. Jump FP/GND in the DIAG box for a temporary fix.
