Hello got a little question I've got a 1993 civic with a d16y7 in it with the d15 manifold on it I've put a turbo on it got the ecu socketed and ordered a basemap for it wired in the resistor box put the ecu in with the basemap chip put in dsm blacktop injectors and now it won't start and no power to injectors with key on where should I start? Thanks in advance.

Check PGM-FI Main Relay, common problem and an easy/cheap fix most times.... AWARDSPACE.COM - Free Web Hosting, Domain Hosting, Professional Web Hosting, Domain registration, Affordable, Reseller Program, PHP, MySQL, Ecommerce

With that said check at the resistor box, make sure there is power going too it AND out of it.

If no power going to it, [resistor box] then check PGM-FI Main Relay, the fuel injector power relays output may be bad, even if the fuel pump relay is working.

FYI there are two relays inside the PGM-FI Main relay
The fuel injector power relay, supplies power to the injectors, IGP1&2 at ECU and some engine sensors/valves/solenoids, [depending on MM&Y] it also powers up the fuel pump relays coil, [internal]
The fuel pump relay only supplies power to the fuel pump. 94

Okay thanks I'll check the relay next I know there's no power at the resistor box but there was when I installed it

Do you hear the fuel pump prime when you turn on the ign. ? 94

Yeah it's definitely coming on every time I hit the switch and making fuel at the fuel rail.

Then check for power at the fuel injector output at the PGM-FI Main Relay, [#3 yellow/black I think].94

I checked for power at the main relay and most of the wires had power specifically the black and yellow one.

Then there is a connection problem between the PGM-FI Main Relay and the resister box plug, you will need to trace that lead and check all connections between the two. 94
