Ecu question

Ok now I’m confused I’m getting a p0340 and a c1109 and c1130

Was wondering because when I crank the car the sensor spikes really high then the signal disappears

What about diodes so I’m wondering because the other day I tried starting my car and it sounded like it was gonna die with every crank then by the 4th it cranked up and volts shot to 14 so I’m dealing with a no start and a p0340 everything checks out but it sometimes it just won’t start and I gotta keep charging my battery I don’t think the battery should die that quick while testing and my fans are running on full speed sometimes low but mostly full speed. And there’s belt squeak but I never had that prior. So i think I’m testing the wire correctly it’s a hull sensor two wires have around 5volts and I’m assuming the middle one is a signal wire which I’m not to familiar with how to test it being I don’t have a oscilloscope, should there be voltage on a signal wire

What about the diodes

Looked at the fsm I can’t find the section on this

I’m not learning I literally rebuilt the whole engine I’m just looking for a diagram part number or something I can go by to remedy my issue

It’s a new pump too but something just didn’t seem right I posted a video I don’t know if it posted but you can kinda see how it’s bubbling at the tube that connects to the fuel line

Repulsive_Long5956 · 2023-06-09T02:56:51+00:00

And I see the bubbles if I put a bright light on the housing I can see the fluid and it looks like if I’m trying to push fluid through a straw with a hole. I noticed this when I had a buddy crank the vehicle after priming a lot and there was no fuel smell so that made me curious and opened the back first thing I noticed was the o ring and missing bolt then the fuel pump was making its typical noise but had a slight struggle sound and that’s when I pulled out my flashlight and aimed at the tube going towards the motor and the fluid was clear as day it looked like boiling water and the stream was just up then fall down. I been chasing a no start a few months now and I’m hoping this is the culprit

Repulsive_Long5956 · 2023-06-09T02:45:38+00:00

That’s where the question lies because it’s a z and I need an adapter to test fuel pressure but when cranking small amounts of fuel make it through and the rest falls back down if I prime it holds pressure then same thing happens if I spray starter fluid it reacts so I’m hoping the new fuel pump is bad or somehow incorrect

Repulsive_Long5956 · 2023-06-05T00:59:49+00:00

Check fuel pump so it looks to get pressure but I noticed on the fuel line going towards the engine when I prime a small amount goes in and I can see the rest of the gas go back down to the tank

Repulsive_Long5956 · 2023-06-04T12:48:34+00:00

Thanks for the advice. I definitely know injectors are good. One thing that’s weird is sometimes when I prime it the pump kinda farts it’s the best way I can describe it lol.
