hey couger I owe you a case of beer!, the fsm i had listed the disty wrong so the wires were reversed on the cas. yahhhhhhhhhooooooooooo im in buisness now. i suppose i just need some resistors for the injectors, hopefully i can find some. thanks guys.

hey guys i will try all of these ideas out soon, ive been away for the weekend so i'll get an update soon on any progress thanks!!

hmmm interesting, and that makes sense. i have checked the cas many times and it functions correctly, so what would make the ecu do this?

well ive got one more final observation, lol. with a test light on the - side of the coil the light will come on when the ignition is on the go out when you start cranking?, arg.

well i will see what i can do about an ignitor, ive got one kicking around off a toyata celica, more headaches for me!!

yep definatly grounded good, checked and double checked that. im so confused

the blue wire goes from the ignitor to the (-) coil and the black and white wire from the ignitor goes to the (+)

hmmm well i wonder if its the coil. im getting 12v to the - and 12v to the + when the ignition is on. but if the coil was bad then why would it spark once when cranking stops?? im gettin massivly confused on this, lol. thanks for the help guys

well i just used a multimeter on pin 37, my first ecu just hada constant 4v signal. the new ecu has no voltage till its cranked then its a pulse signal. the igniter has 4 wires on the connecter side it has 1 black/white and one white/yellow now on the other side it has a blue and a black/white. so do i have this wrong too!??

well the cas is working, and the ecu is from an 87 xt. i removed all other wiring besides the cas, power, ground, and pin 37 and pin 19. pin 37 is spitting out a signal. so that means i must have the ignitor wired wrong, but ive been over it 30 times!. on the input side ive got the black and white wire as 12v ign. and the white yellow wire to pin 37. now on the output side ive got the black and white wire to (+) coil and the blue to (-) coil. and then a wire from pin 19 to (+) coil. any ideas???

ok well ive got spark now, but its wacked out. i can turn it over for say 10 seconds then stop and it will spark once right when i stop. any ideas?

the amp appears to be ok, i checked the ecu again and found out that it bit the dust. im gonna redo some wiring and put in my back up. ok so i know pin 37 is the pulse, on my ecu pinout apparenly 37 and 43 are the same? so why do the both goto the ign amp? the amp only has a spot for 1 input unless i did that wrong too, lol. i wouldnt doubt it at this point.

thanks again skip, so if i put these inline with the injectors it will be a-ok?

any idea on the value of those resistors?

hey guys just wondering if it is allright to wire the fuel injectors right up to the ecu. so on the injector one wire is direct or switched? 12v and the other would run straight to the ecu. im having some big issues with a transplant and am going crazy. thanks in advance!

ok guys just got back from work and checked a few things out, i followed the fsm and determined that the CAS/disty is wired correctly and working properly, however the is no spark. i checked the voltage on pin 37 and found it to be constant, i can turb over the engine and it wont change? any ideas?

well i have the ignition amp hooked up, ive checked the coil, its getting power but is not firing. i will check and see if the amp is getting signal from the ecu. the ecu appears to be functioning as far as i can tell. im really stumped on this!

well as far as i can tell the disty is wired correctly, red power / black referance / white position / green ground so if that is correct then ecu pin 37 should be firing to the coil/igniter correct? is there anything else thats needed to be hooked up to make it spark!!

ive done that and it wont throw a code 11 at me, im all confused now. lol. well i will double check the wiring on the ditsy and then check and see if the ecu is throwing an voltage at the igniter for the coil

well i have no spark, so i believe there is a problem with the distributer/crank angle sensor wiring. i know i have the coil and igniter wired right, the coil has power. so the distributer must not be gettign the signal to the ecu/coil. any thoughts. its an 87 mpfi hot wire style engine (optical dizzy)

allrighty well i go to wait till my buddy gets here so he can tell me if shes sparking!, thanks for the help guys im hoping its just the 2 sensors. thats all the ecu is telling me so fingers are crossed!

the sensors are good, i probably just wired them wrong. so im assuming the ecu sees it as not there at all. there will still be spark though correct?

hey guys, still working out some bugs, would a code 21 or 22 (coolent temp sensor - knock sensor) cause a no start condition? if so does it just cut the spark?

ive got a blinking green light on the left hand side (looking top down with the plugs at the bottom)

allrighty guys heres my problem. first off how can you tell an ecu is turned on an funtioning?, i have all the power leads to a constant 12v, is there one or two that need to be an ignition source?. im having a little trouble with my swap and i thiink the problem is the ecu isnt coming to life. now the final question is what pins need power, ground or a switched source to make the ecu work. thanks in advance guys
