Hey I just got my first z,

heres my intro https://www.zdriver.com/forums/300zx-z32-forums-7/my-1990-z32tt-intro-pics-33922/


This car was running pretty good for a few days while throwing the knock sensor code, then the first night it dropped down to around 20F at night my car would not start the next morning. The security light has been blinking since last week when unplugged the battery.

It sounds like its not getting any fuel, rarely while cranking it it might give a cough as give it a little gas.

I replaced spark plugs a week prior. The battery is fine. I checked the fuel pump relay and I had contiguity. I also ordered a new knock sensor. I will be testing fuel pump pressure tomorrow afternoon and check for a spark. If anyone has any other tips or ideas on where I should look next?

 

Nice Ride there Hootie! I have a 92 TT that looks like yours thats getting a $20k Stage 2 long block motor from Z1 Motorsports this month, 850cc injectors and GT800R turbos with a few other goodies.

I read this post in search of trying to solve the same problem on my 90 NA for weeks now. I was wondering if you figured it out. Every time I think I almost have it solved, no dice! I have done tests and checked things till the cows come home. If you have any ideas, please let me know.

check your coolant temp sensor that is what happened with mine put a new sensor in it and it fired right up everytime after that
