2G My 1997 GST wont start

[Cotye]

I have a 1997 Eclipse GST i recently just bought 500cc injectors for it and when i put them in the car. The car ran than we shut it off than when we went to start it back up it just keeps turning over. Im new to all this and need help.

Thanks in advance

What did you use to tell the ECU it had bigger injectors? SAFC? ECMlink?

Otherwise it thinks you are still using stock injectors. I recommend putting the stock ones back on if you dont have a way to calibrate the 500cc injectors. It wont run well on 500ccs if you dont tell the ECU that is what is on there.

Seems like it would be able to start with them though.

Have you checked your fuel pressure?

 

[Cotye]

Yes and the fuel pressure is fine. I didn't think 500s would mess anything up.

Check spark on all four plugs, then compression, then injector pulse, after you pull the plugs and check to see if they are simply fouled.

You need management to get those 550cc dial in, otherwise you will be dumping to much fuel and it will not tart or it will run extremely rich and risk to trash your engine.
