91' 240 is getting too much fuel - just swapped motors from 97

[mr_wizard]

I just swapped a 97 KA into my 91 240 and currently don't have the exhaust on because it was welded to my old header (need to re weld). I do however have my DC Sports header on, with the EGR valve and O2 sensor attached. But I don't have the emission thing (PAIR valve?) attached because it was rusted so bad I had to saw it off my old header. I'm thinking about just taking that whole thing off? Anyway, there is a 1" hole in the side of the header now where that's suppose to go, I will plug it up once I find something that fits it. Hoping that's not causing the problem... I have swapped the TPS, knock sensor, and coolant temperature sensor from my old motor.

Ok, to the problem. I can start the car and the timing is fine but it only runs for a couple seconds and doesn't get above 500 rpm. If I try and start it again it doesn't do anything at all. So I have to take out the fuel pump fuse and crank it a few times and it starts up for a second or two and dies (using the flooded fuel). Obviously it's getting flooded. So I put the fuse back in and it pretty much starts up right away, then runs for a couple seconds and dies. Back to square one.

There was a guy helping me and he could do a combination of taking the fuse out and putting it back in as im starting it to actually get it to idle fine. After he does that the car idle's very well. We did try giving it gas and it bogged it, but atleast we got it to start. Any idea's?

if it is leaky injectors, swap the ones from the old engine. sure you got the plug wires on correctly?

using the odbII harness or using the plain jane dohc harness?

I'm using my original harness and fuel rail. I forgot to mention I also swapped my old o2 sensor, plugs, distributor, and plug wires. And yes, I have the wires on correctly. The motor runs awesome once I can actually get it to start, I just can't keep it running long enough because it floods itself.
