Hey guys. I just did a zc swap in my 91std. I already had the mpfi done with a mini me in it. Still on the PM6. I got the zc in an it wont start. I have spark but no fuel. The pump is woking and I have 40 psi of fuel. I did a voltage check on the ecu and im not getting any power to the injectors. So I ran 12 v to the main power into ther esistor box and the injectors still will not fire. I dont get it........ I need help bad. Also, the motor was an obd1 motor. So I rewired and repinned the dizzy. As for n e thing else Im clueless...... Thanks....

 

anything???

 

are the injectors obd1 ?

 

they are 330 cc injectors and are saterated. so im not using a resistor box. but still no power even coming out of the computer. im totally stumped.....

 

since your said you are still running the pm6, which i believe is an obd0 ecu, they wont be able to run the high impedance obd1 injectors

you say you are not using a resistor box but yet in your first post you said you ran power to your resistor box, can you explain that, it may help

but i thought i read somewhere about using obd1 injectors with the obd0 ecu, i thought it was something like tie up all the resistor box injector wires together and run them to each injector. dont quote me on that, i was just thinking i heard that somewhere before

 

i have a question?????? i have a 92 civic vx can i put a 1991 civic crx zc engine in it with out changing wire harness?? computer?? trannys mate?? i have a turbo to put on as well whats the cheapest way to set myself up with an intercooler?? i have an intake that came off a 93 or so dohc1.6 bigger injectors fuel rail?? will all this work together??with nos??? lol alot of questions i know but i really appreciate any help or were else to llok for more info.. thanks again!!

 

how in the world did the obd1 harness even plug into the si 1 ?
