Hello guys
I could really do with some help.
Finished putting in the new injectors started the car and drove up and down driveway for about 20 mins to warm up so I could set IAC and TPS. Backed in shed hasn't started since.
I thought it may be loose wire so spent considerable time checking that but no good. I thought the signal from the dizzy might have gone bad so changed the module still no good.
Using the ecm pinout 1227165 down loaded from site and put up by Brian--Tuned.
The injectors have plus 12 volt but don't appear to be firing D15 AND D16 connect to the earth side of the injector. I have put back the old ecu and prom.
a6 Ignition was missing but hooked that up.
The fuel pump wiring appears different without signals on B2 or A1.
Put a noid light on the injectors and it doesn't light up
What else can I check and what tells the injectors not to fire. I assumed it was only the signal from the dizzy module
1988 305 TPI Iroc Z
Thanks in advance

Are you getting fire from the coil?

 

I think a 1 is relay control b2 monitor line if I recall.
does the check engine light come on ? Fuse next to battery good ?

 

yes check engine light on
Fuse ok

 

Have spark at plug
Checked with inline tester

 

What code(s) is it throwing?
