SR20DET Cranks, barely Idles, dies with throttle.

[aioky]

Hello! I'm fairly new to the S chassis, and picked this one up a few months ago.
Everything was fine and she was running good for the few months I had her. changed fluids and all that basic maintenance stuff.

Last week I took her out my garage to clean the inside, started up fine.
Tried to start her back up a few hours later, Battery then died, replaced the battery, and now she does not want to run at all.

Cranks, sputters, sometimes idle to barely ~500-700rpms and dies.
Rarely it will go over 1k-2k rpms, and ill try giving it gas then, but dies immediately after trying to push the gas pedal down.

I checked TPS, running on 0.45 volts to 4.11 volts WOT
so that looks perfectly fine.

I replaced fuel filter and looked for vac leaks a bit.

Nothing so far.

I tried unplugging the MAF, no changes at all I believe.

What else can I hunt around for?

I asked an "expert" on SR20DET'S and all he said was my engine is "fucked" and that I need a full rebuild lol.

Thought I'd ask here before I take that route, Thank you.

Heres a google photo link to my engine, (cant figure how to upload on here)

make sure you have correct fuel pressure
do you have low compression or NO compression?
have you taken a noid light or test equipment to verify good spark and fuel injector pulse?
have you checked timing or removed the cas?

you should also be checking things like the wiring harness connector at the ecu. Make sure its completely seated into the ecu.

did you modify or replace anything else around the time this issue started occuring?

Thank you! I will check those next.

I haven't touched the car at all just changed the fluids first when I got the car.

It randomly just died on me like this, so im hoping its something small
Engine was running fine and literally a few hours after it became like this.

also check battery connections, and grounds.

to add onto what brndck said. I blew a line on my ecu when my battery took a shit and the car was running on the alternator. I've since repaired it and experienced no issues since. a bit extreme but check the things he's mentioned first

Oh dang thats no good!
Did you experience the same issues as I did when you blew the line in the ECU?
Also Update, haven't fixed the problem yet.. but checked all my fuses, and comperssion is still good.

Still trying to track this down

I had this exact same experience a few weeks ago, the fuel line between the pump and sending unit had split.
