Has anybody had any trouble starting their 89-91 fc's a couple days later after moving it from like their driveway to the street and turning it off really quick? I tried unflooding mine by removing the bottom plugs and removing the egi fuse and cranking it 3 times. Put the plugs and fuse back in and tried starting it again but with no success. The engine has 155,000 miles and it's a 91 so i have no idea if it's the original engine or not. Thanks.

 

s5's you should only have to floor it to unflood it... normally only on s4's you have to pull the plugs

if you want try the method i found best.... unplug the huge yellow plug under the steering column (its the plug for the fuel pump) which disables the fuel pump.... then crank it up until it starts and it will stall out shortly (remember you disabled the fuel pump) then plug it harness back in and fire her up and keep her runnin till she warms up... works for me EVERY time

 

ive never had this problem in my s4... ive started it when it was dead cold out side tried to get out of my garage, couldnt, so i pulled back in and let it sit for a few days and it started right up the next time...

 

You won't have the usual small flood problems that you have from old s4's...the s5 ecu is better in that regard. However, if you do the old 30 second shutdown, you can flood an s5 to the point that the ecu injector delay, or the fuel cutoff with full throttle, won't help, and you'll have to do the traditional rotary atf unflood procedure.

IF an s5 motor gets very low compression, say below 80, then it will have hot start/flood problems like an s4.
