Hey, just recently bought this car from a guy, and I was driving down the road, I got on it and it boosted to about 5 psi and right as that happened, the check engine light came on and the car died. I can turn it over , but Im not getting any spark out of the distributor wires and my fuel pump isnt priming. I have a brand new main relay in it, so im guessing its not that (altho when i turn the key on, it doesnt click like it should). I had a guy look at it and he said that I have power to the main relay plug, but no ground. I have a hondata s300 / p28 ecu tuned. I dont know alot about what could be wrong, if anyone has had this problem, please let me know.
