I swear im going to drive this thing off a cliff

Hows your timing?

If you drive or push it off a cliff make sure to video that shiz.
Since its a convertible you could do a Thelma and Louise kinda thing....

What cps sensor did you use? I've had issues with any non oem sensor. What does it ohm out at? Should be about 540ohms give or take

I built the engine, im running an super eta block with an I head and I harness

[Jodecious]

Fuel pressure checks out okay, i replaced and cleaned up the injector harness below the mani. Its been smoke tested with no leaks, compression is fine the engine only has about ~5000 miles on it since it was built and it has a fresh engine ground and steel motor mounts so i think grounding isnt an issue. Even with everything that I replaced the problem gradually gets worse, this started as a small misfire under load about 6 months ago.

so you swapped the engine? or you bought it that way? which harness are you using?

[e30mpg]

vacuum leaks?
smoke tested?
compression tested?
have you check for continuity at both ends of the wire's?
Car ground good?

What is your fuel pressure?

How does the connector under the intake manifold look inside?

Im completely at a loss with this damn car. I have a 1988 convertible 2.7i that will not run for longer than 10 seconds. I have replaced literally everything, injector harness, AFM, injectors, fuel pump, relays,all top end gaskets, IAC, coil, spark plugs, wires, cap, rotor, crank sensor, 2 different ECUs, TPS, 02 sensor, EVERYTHING! The car will reluctantly fire up and run for a few seconds and suddenly "choke" and die. Even if i get the car moving it will buck and stall/backfire like crazy. I am not new to this car/engine but this problem has me completely stumped. Pleaseeeeee heeeeelllllppppp. Im stuck driving a camaro until i get my e30 fixed :(
