silvertop with blacktop ecu

[Toyo81]

no sure if i got all b+ connected, i have battery on ping 1 of 22 ping plug, the +b is 12 but that one goes positive when i turn the ignition, i trace the wire looks like goes to ground, or to power some sensors. disconnected the cable from the plug and connected another cable then i apply +12, and nothing. i check with a noid light the injectors, no pulse. if i put fuel to the intake it tries to start., If i put power to the injectors then ground the positive with a test light they pulse. Igf pulses but no igt. and the wires for the injectors goes to ping 26, on less the blue plug feeds the ecu for the injectors, that would make sense. I what location is the +12 ignition? not able to run codes..

u cant use ressitance to test wires when all the sensors are plugged in
it will give u false reading

efi relay power goes to ecu and the idle motor power and to o2 sensor power

ignition switch power goes to coil and injectors power

u need to have power when on run and crank

anyway sounds like yr wiring is in a bit of a mess

wire it up porperly
power to all places
wire up check light
then u wont fk around for 3 days going round in circles

i dont know what exactly u have wired up or what parts u have used as u havnt given us a proper explanation
anyway best of wire up original ignitor and coil
this way u can rule that out
a silvertop ignitor has big number 201 on it
a black top has CDH1 or something similar

sounds like your setup up is like a mongrel dog
a Bitsa hehehheeheh

i wire a black/white cable on the white connector, i have power to injectors now. car tries to start but dies stays on for few seconds.
The ignitor i have is from toyota #195.
I have the o2 connected, water temp, map sensor is connected in the last intake, knk is connected, vvt is connected and ignition body, STA is also connected. Battery power goes to ping 1 on ping plug 26, not sure if there is another power going to that plug.
On the schematic said that the ping 12 on the same plug goes to +B, but that goes + when I turn the ignition. looks like powers the sensors.
The only thing i don't have connected is the speed sensor, iscv and evap, there is also alot of wires cut. got the loom like that.
Don't have EFI. Will try to got a different igniter to see. this is a mess..

Is your fuel pump running? The circuit opening relay may be closing only with the key at STA, meaning the signal from the AFM (silvertop) or FC pin on the ECU (blacktop) is missing.

Easy to hardwire the pump to check and get things running, but fix it properly some time if this is the problem.

Come on no one on these forums fixes things properly. Hehehehe

Hen,
i have the pump separate from the ecu. pump runs with ign. Not using circuit opening relay.

I want thank you guys for the help...

I still got issues with my conversion.
The engine start but dies after few seconds. when i try to rev it dies faster, not sure if is vacuum related or igniter.
The vacuums should be all block off or what??
thanks
