sr20det not getting fuel or spark!!!

[Kali Slidn]

okay so before anyone asks yes i did search for this topic but no one shared a similar problem to mine.. so here is whats up

so the other day i was driving down the street and hit a bump in the road and my whole car shut off and wouldn't start back up again. upon further more inspection i have so far realized I'm not getting fuel or spark. i have checked the fuel pump its good and i looked over the body harness and fixed what i rubbed through and still same problem. also the engine control relay was blown so i replaced it and still nothing changed any help would be appreciated.. thanks

Your ecu is not getting power. Is the light on the ecu on?

Not sure how hitting a bump would kill the whole car... Although I have an idea lol

Sounds like you need to check all of your wiring in the wheel wells & everywhere else a bit more closely... to include your ECU connection... Depending on how you had the ECU mounted and the severity of 'the bump'... you may have cooked the ECU.

Also, how is the battery mounted? Was it secured? If relocated, do you have a CB mounted close to the battery? You could have shorted out all kinds of stuff if not.

Yeah sounds like it's time for a new wiring harness. First thing I suggest on any car with a swap that is trying to run a hacked up engine harness that came with the engine set. Just save yourself months of headache and get a new harness...then go from there.
