People I have a 1991 Crx si. when i bought the car it had a d15 v-tec swap bolted onto the si trans. drove great for a while then i ran into some issues. Went out one day and the car wouldnt start. I checked FUEL PUMP, FUEL PUMP RELAY, DISTRIBUTER, SPARK PLUGS AND WIRES and prob other things i dont remember. so its getting fuel and spark so i dont know if its down to a wiring problem or what. it also threw an injector code and a O2 censor code one night when i was driving it hard and went off within 5 mins. Yet the car drove for a month after this happening. thinking maybe i am getting fuel because i can smell it but maybe an injector is plugged up??? the car cranks and when you give it some gas it sounds like its grabbing to turn over but then continues to crank. PLEASE HELPPPPP

 

Check your ECU, make sure your wiring connections are clean, and please, double check your main relay.

 

Starting to think its a wiring or ecu problem but idk what to do, the guy rigged the d15vtec to run off the stock ecu that was made for non vtec and stock wiring harness and jumped wires but idk what to look for.
