car: 91 Dx Hatch
motor: Jdm D15bvtec
problem: so i did a dpfi to mofi swap and then used a jumper harness to convert to obd1
i have spark, fuel pump works, timeing is dead on

my problemb is that i am not getting injector pulse.

i have traced all wires and double even tripple checked them
is there anything that i could be missing that i am over looking a ground or power wire that i forgot. any ideas would help im lost.

p.s
if i take a wire and ground it then splice it to one of the enjector wires off the ecu then the car will start .

any ifo would be helpfull

 

Make sure u have the right ecu..the one im using is a pm6 the 91 crx si ecu to pop da vtec

 

i got PM6 from 91 crx si, and that ecu can't handle vtec by itself, so if you have vtec engine its possible that wiring is different

 

Do you still have the resistor box?

 

You have to change between peak and hold and saturated injectors to use or lose the resistor box.

 

x2... if your using obd1 injectors you have eliminate the resistor box and tie all the wires together. give that a try.
