M42 stalling.

[loganwept]

Hi so I was driving my e30 to Oakland airport and it was fine. On the way back it started losing power. It got to the point when when i was on the freeway flooring it going 55. It started hesitating and throwing a CEL. I was almost home when It started bucking and would barley go from a stop. I died in my driveway. I got a stomp test code of 1222.
I cleaned my ICV my AFM and my throttle body.
Gonna pull the plugs and look to see what they look like.
Good question is, is my fuel pump supposed to be running while the key is turned to the AUX position? If so. It's not may be dead.

I have a new o2 sensor.
New plugs.

I also have
A noisy fuel pump

Thanks in advance and sorry for my scatter brained ness


Update: I put a different AFM on the car. Still wouldn't start. Still throwing the 1215 code.
I unhooked the battery and reset the code still no start but now it's not throwing the 1215 code... I'm stumped.

it might still make noise and be on its way out, thats what happened to my FP. I put an aftermarket from TREperformance, no issues in the past 2 years

Cool thanks.
UPDATE!
It's no longer throwing a 1222 code. Now it won't start but sputter while turning over. And it's throwing a 1215 code.

No other inputs? I just bought a fuel pump so ill throw that at it and see.

Can you hear the fuel pump running? Do you get 12v on the small terminal block above the main 12v block on the firewall? I am betting on a broken fusible link.

[loganwept]

The pump is running. Im gonna check the relays.

Turned out to be a clogged catalytic converter... Stupid lo car problems. Scraping in speed bumps. Hollowed it out not my car sounds like garbage.
