DE swap in pignose not working well

[edmorl]

Recently dropped in a KA24DE from my fully running parts car into a 1989 s13 shell.

The KA starts, idles a bit and dies. It lasts a bit longer now since I swapped the wires. The MAF has also been swapped. The second I give it gas it dies right away.

The engine harness is from an automatic car and I spliced the dash harness to mate it to a pignonse s13 chassis. AC and EGR has been remove (with block off plate)

Previous owner also hardwired the fuel pump because he said that the fuel pump relay wasn't getting any power when he had an sr20 in there.

There's also no electrical components working in the cabin, lights, radio, windows, etc.. (But it all worked when the sr was in here)

Gas in the tank is from summer 2011.

Anybody have any idea to what is going on here ? Oh and fuses are all fine

Im willing to bet wiring issues bad connections in numerous places maybe shorting out. If it is just buy a completely uncut harness and install that instead of messing with something that could waste a ton of your time

I have to cut the harness.... KA24DE's never came in 89' and 90's

I'd double check that the egr block off sealed properly. Spray some ether in the egr area and see if it revs up. Could be a vacuum leak coming from there.

the only thing you have to change when you put a dohc motor in a single cam shell is the engine harness. so check alll your wiring and your fuel pump definitely change the gas and putgood gas in there.

Second the vacuum leak at the egr plate sometimes gotta put a lil rtv to get it to seal properly.

Instead of spraying ether. Water also works work. Dont catch your car on fire.
