I have injector questions if anybody can fill me in

[Johnbalderas90k1500]

If any body can share some great wisdom with me I would like to know all the components that turn on and control the injectors. I have a few problems with my vehicle and I just need to clear things up.

On a throttle body injection vehicle there are several thing's that control the injector's, the main ones being the computer behind the dash, and also the igniton module in the distributor, and if the ignition module fail's the injector's won't spray.

Thanks what if they shut off intermittently. Ignition module?

 

[DRAGGIN95]

It could be that or maybe wiring, I would inspect all the wiring really carefully for break's.

Cause it won't stay running longer than 5 seconds and my injectors cut on and off. So it idles rough and I can't drive it. It only runs smooth and stays running for a few seconds when I pour gas down it. It chokes and automatically stalls when I hit the gas

That could also be a fuel problem, have you checked or changed your fuel filter?

I blew through it and it had no restriction and it was pretty clean which surprised me . Already changed the pump. It does not look like it's getting low pressure it just the injectors will pulse after it's started than stop and it will start to die and they will pulse one more time and it will stall. Mind this happens all within about 5 seconds

I would definitly have that ignition module checked out!

Thanks for the input I am gonna try to test it. Is there a procedure?

 

[DRAGGIN95]

I believe there is, but I would take it to a parts store and have them test it, it's usually free.
