Default massive fuel dump problem

first off I havent done any mods to my car in a couple years.....

last week I had my car sitting at idle for about 30min., didnt get anywhere near as hot as it does on track, and on my way home the thing started running funny and felt like a stutter, wideband said 11.0ish during cruise when it should be around 15.0, went past my house and turned around up the road to "clean it out", but before I got on it, I made a u turn and noticed a big cloud behind me, I turned the car off and got out, it was raw fuel burning in the pipes, well I ended up limping it home.... it was for sure raw fuel dumping, I pulled the plugs and cyl 5 seemed like the culprate, I figured it was the fuel injector stuck opened, so I got a new one changed it out and still got a major fuel dumping problem, but now it seemes like all cyl. are dumping because I put new plugs in and about 5min. of run time they looked like they had 100k miles on them, all compression checked to 150+ on all cyl., leaves me thinking its an electrical issue, but during the testing of various things while I was running the car, cyl 5 got so much fuel that the thing hydro locked and broke a connecting rod, so now I gotta pull the motor.... it also had a p0200 code wich is kinda vague..... and when I say dumping fuel I mean it was accually dripping from my exhaust connectors, I checked and double checked all the upper injector wires, I just need to check the wires to the pcm, but I'm wondering if this might be a pcm problem or somehow all my injectors (lucas 42lb) are failing, if I use a volt meter, how can I check my injector wire plugs, and what should they read?, any ideaws or help would be great....

btw, in the marked for a forged short block now....

Try ohm testing your injectors, from your description they sound pretty much fried.

Wouldn't have to be all 8, 1 injector stuck open can dump all the pressure out of a system in a matter of seconds. 2 or more and it can get very nasty.

"I put new plugs in and about 5min. of run time they looked like they had 100k miles on them,". 1 inj would not foul out all 8 plugs.
