i dropped a b20 into my da and i have had nothing but problems, car wont start, shoots out fireballs, makes loud poping noises, smokes out exhaust like crazy,( basically its pretty sweet) but im stumped that during a long craniking attempt to get it started it threw a check engine adn the ecu was blinking red-red-red- pause red-red-red pause over and over again adn i have no clue as to what that is

 

My 90 has a b20, what ecu did you use? obd0? There's a sticky at the top of the forum that has all of the codes so you can look it up, and how to look it up. Basically the system works like this, you have long flashes, short flashes, and pauses.

long-long-short = 21

short-short-short = 3

long-short-pause-long-long-long-short-short = 11 and 32

From there, match it up w/ the list and you'll be able to figure out what codes you're throwing.

 

ECU code 3... Manifold Absolute Pressure Sensor.

 

would this prevent my carr from starting though? sinch im running a b20 i used the firewall mounted sensors from the b18a but used a b18b manifold which is less restrictive, sooo in order to hook up some of the sensors i had to use small vaccum t fittings adn rubber plugs to go into intake manifold, soo im not sure if this would have an efffect on it reading, but if u can help me out i thank u again
