Another 4.3 question......

[SMWS6TA]

Been getting some hesitation and misfires on the Blazer.

I know, I know..."burn it to the ground" Can't afford too....

So the codes that come up are

P0200 - fuel injector circuit malfunction
P0205 - fuel injector circuit malfunction cyl #5
P0300 - random misfire
P0305 - misfire cyl #5
P0155 - 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1) - this doesn't surprise me after 175k miles and 3 head gasket leaks, it's due to change out.


This thing has the spider CSFI system. Do they have individual injectors or is it a complete system? It looks like you have to get a complete system but I see individual "injectors" and the "injectors look nothing like what I know of (think LSx style injectors).

The napa one is the only one I've heard you can replace poppets on. I'd just do the entire thing since if youve got a problem with one part its going to have more problems coming up. No sense in tearing apart multiple times.

Check the wiring harness for the spider, maybe something got pinched. Also check your connectors and make sure all the pins are making a good conection. I'm pretty sure you can just change one injector but i'm not 100% on that.

I did that yesterday. No pinched wires. My cousin got back with me and told me they can be switched out individually
