Main Relay?
Hey guys i've been having problems starting my car when it's hot, plus my ECU is throwing a code 16-fuel injector. First, i was wondering if the main relay has anything to do with the ecu giving a code 16, or could it be the injectors themselves. Second, i removed the main relay but it only took like ten minutes. It just seems odd because everyone on here says it's like a bitch to get it out.
I wanted to make sure that this was the right relay so i took pics, see attachment. I need help with this ASAP because i have to go to school and run errands today so i need my car to work, and i can't return this relay if i open it and it's the wrong one so anyone please help. Thanks in advance.

Cool, thanks for the reply! Actually, tested the car without the relay in and the fuel pump does not activate, and CEL light does not go away, plugged it back in and car starts up, so that's it!
But i'm still unsure about the ECU throwing code 16. Does anyone know if code 16-fuel injector has anything to do with the main relay, or could there still be something wrong with the injectors?

It's not so much a biatch to get out as it is to get back in. It's hard to get back in simply because you can not see if the bolt hole is lined up if yours is like mine is(was). Anyway, while you've got it out, resolder all of the solder points. Re melt the solder and add a tad to each point, and it should fix the main relay. It did mine. Be sure to do all of the solder points. Mine threw a fuel injector code, and i added fuel injector cleaner, and it fixed it.

sometimes you get that from a faulty injector....the injector could be leaking......or not spraying correctly.usually when code 16 hits.its means what it says..are you running Dpfi or Mpfi?

your code 16 is probably being caused by the main relay, since it also powers the injector resistor box thru pins A13 and A15 on the ECU, in addition to controlling the fuel pump
