Hi b20 I have a turboed 1996 honda civic dx I put the motor in myself and the turbo, it has a p28 chipped (not tuned yet) . I think the turbo is a eBay turbo but anyway all was fine at first. Ran and droved fine for about two months till one day I was cruisen wit my system blasting till I seen the check engine light popped up then the car died I thought it was the fuel pump so I replaced that still no good then I replaced the battery and main relay. I still get no spark or fuel and now I am clueless I was going to jump the plug to read the diagnostic codes but I remembered I replaced the battery so now there's no code so iono what to do any help would be aprecciated

I checked the main relay with a brand new one still no good and fuses I looked through them all unless you know the exact one? I even put on a syock ecu and a spare distributor today same problem no spark or fuel so dats..

New batter
Different distributor
New mainrelay
I tested two fuel pump both working
Two different ecus
Tested fuses
Tested ground for ecu... all that still; no spark or fuel

Since you have an OBD-II car, attach a code reader/scanner to the Data Link Connector, located under the dash, and read the codes. Disconnecting the battery may or may not have erased the codes. If that doesn't shed any light on the situation, check all under hood and under dash fuses with a test light or multi-meter:

Pay particular attention to the ACG (S) (ALT) fuse in the under dash fuse box. If all codes were erased, try "forcing" a code, by cranking the starter for 20 seconds.
