i recently did the mpfi swap on my d15, i got all the parts i need such as distributor, complete manifold, wiring, ecu, i did everything all the wiring and stuff, now my engine cranks
and everything but it doesnt turn on, fuel pump is good, also ecu (i tried many ecus just to check if it was the ecu). with a power tester thing i check if the injector wiring was getting any power and yes it was, but just for like 2 seconds then some clicking noise clicks and the power on the injectors go out, the clicking noise comes from the main relay, or maybe some other relay close to it [i tried several main relays and i still get the same thing.
at first i was using the pm6 ecu but my friend burned it by accident, so now i have a pg7 auto and manual most likely im going to use the manual one but some people say auto is better, is that true?
thanks

 

does anyone have any idea what could it be?

=[

 

How were you testing voltage on the injectors?

 

I've never heard anything about anyone using an Automatic ECU on a Manual transmission car.
Always, always, always check all your fuses. Check the power that is GOING to the main relay. Check all yellow/blackstripe wires.

 

i was testing the injectors wiring with this screwdriver looking thing
and i checked all fuses and yellow/blackstriped wires
