Is this the correct ecm

[PaulRV6]

To be clear about this I didn't want to bore everyone with info that I might have thought was not pertinent but here goes.
This is on my 84 hot air motor that is on my test stand. It had an accel dfi stand alone system on it but never really ran good so I swapped over to a stock 87 computer and harness. This trying to get it to run on my stand with a stock chip and no calpack. The electronic components are all 87 components.
I don't know if this helps or confuses things.

With all that said I am still trying to get the noid test lite to come on.
I don't have the MAP sensor plugged in, do I need that? Thanks guys

dont need map , whats plugged unto the c100 firewall end of harness that attaches to fuse block
you dont need much on that end but do need to supply 12v to the fp/inj wire at C-6 pink/ blk and 12v to D4 and B4

Correct and I have that and also G6 to my fuel pump. What I am wondering is it doesn't even get fuel to the injectors on cranking otherwise it would pop. So what tells the ECM it is cranking (RPM) to fire all the injectors simultaneously on start?
Earlier when it fired it must have been some remains of the eather.

cam sensor signal needed to determine 25 after tdc#1 compression , then it looks at the three windows at crank sensor events to fire correct injector and to advance to the next ign coil , then repeat and resync when the cam sensor triggers tdc again
if it looses the cam sensor after run it will batch fire the injectors

what about ses lamp.. is it steady at key on ,
scanmaster data connected if so whats the readings

I don't have the ses lite connected but I'm sure it would be on. I have a turbo link program that reads off of the ALDL connector but for some reason that isn't working.
So I am still trying to figure out why the noid lite isn't working when I crank. I am going to check and reset the cam sensor cause I'm pretty confident the wiring is all there. So it doesn't get an RPM from somewhere to send to the ECM or is that what the crank sensor does?

look at steve woods no start tree
i posted the link ..here it is again

No Start Tree

..first step is confirm the ses lamp is steady with key on
you can connect a bulb between A5 and 12v
get past all in step 1 then post back

Ok I will work on that tomorrow. But what will the ses lamp being on tell me?
I just want to figure out why I don't get the noid lite to work. Thank you
