I've never working on one of the EFI truck engines...but is it possible to remove one of the injectors and see if will fire (pulse) quickly?
Not really. The Ford dealer has a tester they can use to test them individually, but the fuel rail holds them in place as well as feeds them fuel, so it would be hard to see if they are spraying. You probably could put a stethoscope on them and hear them clicking.

I would imagine that the firing happes so rapidly that you would not see any fluctuations in rail pressure either if you had a gage on there? You would probably have to have a very sensitive pressure transducer and track it on a chart recorder
Trying to think of a way to see if they're firing or not, or if they are just firing at the wrong time.
THANKS EVERYONE IT RUNS!!!!!
It was the PIP i changed the distriutor and roughly put it back in. It stared right up .
I have to set the timing (its not even close) runs ruff but at least it runs...

Cool!
I just spent several weeks dealing with the distributor on my 1986 Tempo with TBI and EEC IV. Looks like the distributor just needs to be stabbed in the general area of where it belongs, the computer handles it all (assuming you've got the plug in that yellow/green wire down by the electrical connector at the dizzy).
I also figured out these PIP sensors are not all the same.
Thats true but i would not have gotten it yet, if some one had not said that the module is not the pip....lol
Oh well working on the positive grounded points cars are roghting my brain...lmao

I know what you mean. These guys have saved my butt more than once. My trucks run good, and it's because of the tips and tricks I learned here.
Even the best of us (which ain't me) can learn a new trick every now and then.

Since you are new to this EFI game, I am not sure you know this, but to set the timing on these things, you have to take control away from the computer. You do this by pulling the jumper plug out of the SPOUT connector. If you follow the bundle of wires leaving the dist, one of them will separate out by itself, and it will have some sort of connector in it. You get the engine warmed up, turn it off, set your timing light up on #1 like you would do on a older engine, and take the SPOUT jumper out. Then start it up and set the timing to the the sticker on the radiator or the valve cover. Before you do that you might want to crawl under the truck and take some white out and mark the balancer in the correct spot. You might have to bump the engine over, but I find underneath is the best place to white out the balancer so you can easily see it from above.
After you are all done, don't forget to plug the spout back in. You will get a error code if you leave it out, and no timing control. What I have also noticed with these things is you have to drive them some before they sort themselves out. After about 3 days of driving it off and on, you will notice it will run different, as the computer learns and adjusts itself.

That was me back in post #10. Glad you got her running.

How it works with my Bronco is, after any kind of work on it, I clear all codes. I usually disconnect the positive battery cable for like 30 minutes or so. Hook it back up, and take a nice drive around town. By the time I get home, the computer has relearned most of it's stuff. Gotta go through a couple of heat up/cool down cycles to nail it completely.
Seems I really need to do some reading up on these sytems myself....several terms I'm not familiar with.
PIP? SPOUT?
Welcome to EFI.
oldfuelinjection.com (used to be called Ford Fuel Injection) is a great site to learn from. I am not at all ashamed to say I learned just about everything I know about EFI from people here on FTE - along with some web sites and a book recommended by Franklin2.
