ok i have a 88 crx si with a turbo ls motor i was out having the car tuned and be fore we got started the car was at idle then started runnin rough then died. i had to let the car cool down then it started but when it warmed up agin it died agin but now it wont start even if i let it cool down ive never seen or herd of anything like this because i have good compression its 160 straight across in a 8.5 compression motor there is spark and fuel and timing is dead on i have no clue whats wrong one thing i noticed tho is the plugs are getting fuel fouled by being too rich but when i adjust the duty cycle down it has no effect if anyone has herd of this happening or kno's any thing that could help me let me kno thanks........

 

im having a similar problem except mine just stopped running a month after my mpfi swap

 

i bet its your dizzy. I had that problem once when the screw that holds the rotor on came loose. it would still spark but not consistantly

 

yea i checked the rotor its still tight its weird dosnt make sense

 

just throwing this out there but maybe the heat range on your plugs is too cold. try switching to one step hotter plugs

 

sounds like your ecu took a ****.....

 

yea i tried 3 diff ecus too and had the same problem on all of them prob still aint fixed

 

Did you guys check the coil the ignitor, the main relay and the map sensor ?

 

cough spark plugs cough cough

 

actually im gonna change the coil and ignitor and main relay tonight and its got new zex plugs i let u kno how it goes

 

werd.

 

I had a similar problem with my zc turbo in my crx. On hot days or anytime around noon when the sun was out my crx would crank but not start. it ended up being my main relay, but your prob sounds a lil different. What kind of fuel management system are you using? stock or aftermarket fuel pump?

 

well i just changed the main relay and that wasnt it.. i was using BRE "bens rom edit" and i thought that was the problem cuz the software has no cold start function so it just floods the motor till it heats up then last night i went back to Turbo EDIT and still nothing so tonight im gonna try and change the coil maybe it just has weak spark or somthing also im running a walbro 255 fuel pump its still good u can hear it before start up when u turn the key on but i got some starting fluid also so if it dont start now then i dunno but ill keep u posted

well its been a while but i got the situation figured out it ended up being the fuel gauge went bad on the cluster.. pretty stupid but i discovered it after i pulled the fuel line off and primed the fuel system and it was bone dry lesson learned... hopfully this will help someone out in the future. thanks...

 

lol that sucks man damnnnnnn
