My vehicle keeps randomly dying and has troubles turning on. I automatically thought fuel pump. So I replaced fuel pump and filter along with the sending unit. It still had the same problem so I replaced the fuel pressure regulator and still the same thing. I figured maybe the fuel pump was a faulty one so I replaced it again and still same problem.

 

First thoughts would be icm or injectors. You might want to ohm the injectors. Does it fire right back up a intermittent issue or does it struggle to fire back up ?

 

Okay. And sometimes it will start right up sometimes it wont.

 

Not sure if you have tpi or tbi, but you should check for spark and injector pulse or spray if it’s tbi when it occurs. A intermittent issue can be a bear to find.

 

I replaced the Icm so far it's doing good still lack of power but I'm facing the hard truth that the engine is getting a little blow by action. I'm probably just going to run thick oil Haha. But thanks, I didnt of ignition because it didnt feel like it but I guess it was.
