Yes. They all came from different places so those are ok. For sure.

So i have
high flow walhbro fuel pump
19# injectors
E7 heads
HO plenum
Stock mustang throttle body and egr
TPS
and the DA1 computer is still in.

I know those are all correct

Update! Thank you for everyone's help! BUT... I was duped! I was sold a non HO cam. Which entirely explains why 3,4,5, and 7 were not firing. All that work!!! UGH!!!!

For future reference: if this question ever comes up again then they got the wrong cam too.

3,4,5,7 no fire wrong cam
1,2,6,8 distributor backwards.

I realized i got the spark plugs for E6 heads not the E7s. There is a difference between them.

Spark plugs 3,4,5, and 7 were black. Coincidentally these are the spark plugs that you switch when doing an HO conversion. The others were normal.

The correct spark plugs and wires helped with throttled firing a little. Couldn't take it out for a test spin though. Will update tomorrow when I drive it.

You need only measure the volts at the tps green wire with the key on.  Look for between .4 and 1.0 with the throttle closed.  Probably not the problem, though. I can watch mine bouncing from 15 (my base timing) to 26 or sometimes 28 at idle in gear.  I think you're chasing balloons.  You did swap the EEC with a HO EEC, right?  How does it drive?

I got the DA1 which is for a manual I am reading. But I step on the throttle and it won't move.

Apparently a 30 year old starter does not like to be jostled around to get headers in! I put her all back together.... turn the key.... and CLICK! I am like... wtf... So I cooled down for the night and told myself I would come back to it today. I already knew my starter went bad so I replaced that and the solenoid. After I replaced those it fired right up! I couldn't be much more proud of myself accomplishing such a project on my own..

BUT LAST QUESTION.

When doing the timing you
1. Let it warm up.
2. Remove the sprout.
3. Advance or retard the timing mark to 10° BTDC.
4. Tighten down the distributor.
5. Plug in the sprout.
6. Let the computer do it's magic.

My question is does the timing need to be readjusted to 10°BTDC after the computer fixes itself or do i leave it alone?

It's running at 26 BTDC now.

The first pic is the charcoal canister, look for a port under the upper toward the front.  The second is the MAP sensor, VERY IMPORTANT since you're staying with speed density.  It connects on the back and you can connect it pretty much anywhere it fits, but it must have full vacuum.  The vacuum hose labeled S on the tree stands for "Source" which means it supplies vacuum to all the accessories on the block, you'll want to find a large port on the back of the intake, I can't remember if it's on the upper or lower, but you can bet that only one will be large enough. It may be a couple inches in under the upper.  If the upper is tightened down, feel around with your fingers under the back.


Sweet! Thanks! The HO Plenum hooked up a little differently than the stock one. The charcoal canister is hooked up on that side so it just goes to the upper intake. And the MAP sensor goes there too. There is plenty of hook ups down there. Lucky me...

Now i just have to get exhaust hooked up!

Thanks for everyones help!
