ahahahah, such a funny question on my part
anyways, i went out and tested the plug wires again and the noid is beeping right away.

it may either be the opti not sending, or it could be a ground somewhere shorting at high temp?

i couldnt get to the car today though. tomrrow

Ok, ive went out and did a few things, it looks like the only plug that doesnt make the noid light beep right away is the drivers side most forward one, the noid doesnt fit snug into it though so i think thats the problem, because it reads 13 v.. i have a multimeter set up on the fuel pump grey and ground and its reading steady 11v at idle.. not great, but not bad i assume. maybe at wot it changes, ill have to get my fiance to press the gas for me.

ok, i had the car idling outside, went out and it was off, no v to pump, but fuel pressure still there. so i tapped on the plug to the opti and it turned on again. might be coincidental
