So ive been slowly getting my rb running a little better every day. So heres the breakdown:
Car will start, but it takes gas to get it to start when cold. It will turn over and turn over and try and start a few times. Battery is brand new 800cca.
-Car once started will run rough, and it may die. However if it idles for more than 10 seconds or so it will usually stay running.
-Car will make it all the way to warm and idle up.
-if i where to shut it off i may have to apply gas to start it again.
-for whatever reason my stock tach wont even work, and my aftermarket tach wont work. I even wired in a 10k resistor. Not sure why.

I replaced the coolant temp sensor made no difference, pretty sure i wired everything correctly. If anyone can give me a hand id greatly appreciate it!

Thanks,
Dakota
