Car won't start

[anovelli2002]

i am sure that this has been brought up many of times but i am having a really hard time with my z. i have a 90 z32 and recently put jet sport 500 turbos with ashspec 2.5 inch pipes on the car and z1 poly motor mounts and the car continues to go into safety boost and i think i maxed around 9-12lb. i have many of other upgrades but i was told that the knock sensor may be the issue to my problem so i decided to ground out the sensor with out using any resistor. i have spoke to many people and they tell me that this will not cause the car not to run but once i did it i haven't been able to start car. i have check and replaced the cas and ptu. i have brand new 2nd generation injectors and have fuel and spark. now i am at a loss ever since i grounded the sensor it will not fire it sounds like it wants to then changes the timing on me. i have replaced timing belt and idler arm less than 5k

I hope someone will respond and not just view

1) I'd unground that sensor. Better to leave it open than grounding it. You run a lot of risk just randomly grounding things.
2) You should have a knock sensor in your higher HP car, even if it is relocated.
3) I'd try swapping ECUs with a known good after you've hooked up your old busted knock sensor. I'm thinking you may have fried it by grounding it.

Thanks I'll try it

I spoke with jwt and they swear that grounding knock sensor cannot hurt ecu would you know of anything else I could have damaged by grounding to upper intake manifold
