I got the car back together after dropping the tank and doing the sending unit and now it wont start. It tries and it will "run" while the key is turned but its so rough that after you stop it does a second later.

I checked the codes and its 33. Nothing up front changed and it was fine before. Could it be something else and the 33 is just because it wont actually get up to RPM and create vacuum?

I'm pretty confident the are correct but could I have the lines for the sending unit hooked up wrong? Obviously the pressure line has the fitting but could the rubber lines be wrong causing this?

'91 Z28 5.0. I don't really know what else to check besides the vacuum lines the code 33 would lead me to check.

 

Nevermind. This was the result of a severe brain fart on my part. While the car was down I also swapped the computer thinking its the last piece to try and get my fans working. While sitting in the dr. office tonight I had the revelation that I forgot to swap the memcals. I was trying to run my 305 TPI on a V6 memcal.

No wonder it wouldn't run.
