Will not start, no signal to injectors

So I replaced the head, and now the engine will not start. It does turn over, and is getting spark, and fuel. But the injectors are not getting the signal to spray fuel. I have trouble shot the problem a little. Is their anything I could be missing, like some hidden relay or fuse, or maby something I over looked.

How do you know the injectors are not getting signal?

Cam sensor not plugged in? Module. ECM fuse?

Re: Will not start, no signal to injectors

It may not have an ecm fuse, if it does it would be with all other fuses. The module i'm referring to is the ignition module.

Re: Will not start, no signal to injectors

There are a couple different modules, I think they all have to do with the spark. There is a fuel injection control relay but that is good. There is also a ignition switch that goes behind the ignition lock cylinder. but I dont think that has any thing to do with the repetive pulse to the injectors. What do you think.

Not sure what you mean by scan tool, sounds like I need to buy one. Could you please explain.

Re: Will not start, no signal to injectors

A good scan tool is a VERY expensive piece of automotive equipment. What I'm interested in is if there are any codes being saved in the computers memory.

Re: Will not start, no signal to injectors

Nope checked that earlier today. The only code was the coolant temperature sensor. I was hoping that would help me out but sence there was not a important code, I am at a dead end. Unless their is something I am mising or maby the wires got cut some how. I am trying to look up diagrams right now.

Re: Will not start, no signal to injectors

How many injectors? MPFI or sequincial? or throttle body. Sorry eagle talon is a little off my memory. Been a while since i've seen one.

4 injectors, throttle body. If it were to help it is the same car as the Mitsubishi eclipse everything is the exact same.
