Well my 91 civic will not start. I went to work fine but when leaving I got nothing. It turned but no ignition? I checked fuel to the throttle body (DPFI) and I checked spark. All was fine. I tried replacing the injectors thinking that was the only place left. Please help, I checked the led under the pass carpet and only 1 blink and nothing else. What else could it be?

. Check all under-dash and under-hood fuses with a test light or multimeter:

Test each fuse carefully and thoroughly; otherwise, you can waste a lot of time and money. Pay particular attention to the ACG (S) (ALT) fuse, which is likely Fuse No. 12.

. Perform tests in Sections A and B:
