Fueling & Injection - car wont start after fuel injectors install

alright i know i have to get a tune for my car just cant do it right now. but i got a 402 and was running it on the stock injectors just to move the car around here and there. but now i put in new 42 pound injectors i know thats not what the motor calls for, its a little much but im planing for the future. (just incase)
and now the motor wont start. i pulled the number 1 plug and it was completey black so im guessing i fouled out the plug. but my question is should the car at least start without a tune just so i can move it around ?

Well I just changed my fuel pump and installed new injectors. All I know was my tuner told me not to even try to start the car. I went from 28.8 to 42 pound injectors. He came an put a new tune in the car that scaled the injectors! We then started the car right up with no problems.

You need to change the tune as soon as you install the new injectors. Most likely you fouled the plugs.
Phrased differently, don't install the new injectors until you are at the tuners or have the ability to change the tune.

You damn near doubled the amount of fuel you had and you're wondering why it won't run?! :lol:

It probably won't start without a tune. Even if it did start you wouldn't want to run it like that. You are dumping a lot of extra fuel into the cylinders. Put the old injectors back in if you need to move it around. You need to have the injector scaling changed before you can run it using bigger injectors.

ok thanks guys ill just put the stock ones back in for now and wait till i get my custom exhaust done so i can go get it tuned.
