Car Won't Start after FMIC install (yes i've searched, gone thru the fsm, etc)
#28
Im gonna take out the plugs tomorrow just to verify they aren't soaked with gas or oil. Then after that Im not sure what to do.
How can I verify the injectors are actually firing without ripping the engine apart?
Is there a way to verify the ECU is doing whats its supposed to with out having the crazy mazda diagnoisis thing?

I'm still wondering why your fuel pump jumper doesnt activate the fuel pump. It doesnt matter if your injectors fire if you're not getting fuel to them. You sure you got a clean connection when you jumpered the plug with the key in the ON position?

You can look up the wiring diagram for your car and then check the voltages of the injectors at the ECU and also test the resistance of each injector.

Ok so today im going to check the plugs for gas/oil
try the big unflood procedure in case it is flooded (i did try the fuse trick and such already)
check the ecu that its sending voltage to the injectors
check the impedence of the circuit to the injectors @ the ecu
then remove the ecu and open it up.
What should I look for when I open up the ecu, if something is blown will it be obvious? I know what blown electronics smell like, but I've never opened the ecu before.

OK here are the results, really looking for some input here.
Car was not flooded, rotors were dry as a martini, no smell of gas, no residue.
Compression is good, over 100 on each rotor face front and rear
Plugs not coated with oil, had some carbon on them, but nothing major
There are three plugs I found that are not connected to anything. Im not sure what they are, maybe diagnostic or something. They werent connected before the car quit running
My ECU is numbered N333 18 881, this would indicate its been replaced w/ a remanufactured unit correct?
I opened up my ECU and saw some disturbing looking soldier joints on the back of the board. Could this indicate my ECU is fried?
Thanks for any input you can provide!

Just curious.... post some pics of yourr FMIC install, like the pipe routing and such...
However... A three position mounting spot like that usually means a power transistor.. and it looks like they got hot or were re-soldered.. I don't have one at my disposal anymore to confirm that though..

its the old school trust kit, so everything runs on the passenger side. Im at work now, I'll post a pic when I get home.
the code on the ecu according to rotary resurrection, its a remanufacturered ecu, so I dunno.

The injectors are SUPPOSED to show voltage all the time until they are pulsed. Have you checked all your under the hood fuses/etc? Sure you didn't drill through something or knock something off as you were installing the intercooler?

yea, the ecu pulses the ground to get them to fire. i dbl checked every fuse, short of stripping apart the wiring harnesses to check for breaks, everything looks good, everything is connected, and nothing is damaged that i can see. The only thing I can think of is that maybe a wire inside on of the harnesses was brittle and split.
and reading other threads about ecu/injectors not firing, i dbl checked to make sure that the ground for the ecu was connected to the rotor housing, which it is.
