CEL on after fuel injector replacement

[Maverick0007]

Here is the deal, I replaced the stock fuel injectors today with Accel 24lb fuel injectors and now the CEL comes on and I can smell a burning smell. Any ideas?

What code/codes triggered the CEL?

I don't know, I don't have a code reader, I just thought someone would have an idea.

You need to have the code/codes read.

Good luck ....

lol, makes sense. I am going up to Autozone later this afternoon to get some permatex gasket maker. I am installing the supercharger this evening. I will get back to you on the code reading.

One idea, maybe I'm off but: You are now running 24 lb injectors. Your truck's computer thinks you've got 19 lb injectors in there.

How do I get it to think they are 24lb injectors?

Why did you put 24# injectors in?????

You need a new MAS calibrated for the larger injectors.
19# should be good up tlike 275 HP or somthing, forget the exact number but unless you are boosted or heavily modified the stock injectors are fine.

Also when you need larger injectors often you need more fuel pressure a bigger pump.
The MAS is calibrated to the PCM based on the injectors in the intake manifold.

Burning smell = better check your wiring job.....
