Let's begin with Setting the timing by Ryan M @ http://www.fuelinjec...com/page71.html
Yes, you are correct, pull spout off and then set the timing.
Check it out & compare to your process.

Next is try a Self Test for Diagnostic Trouble Codes (DTC)s by my pal, BroncoJoe19
A helper can assist you by counting the codes. Some use their smart phones to record them.
BEWARE OF FAN, BELTS, PULLEYS, HOT HOSES, IGNITION HIGH TENSION WIRES, AND ENGINE COMPONENTS
The engine temperature must be greater than 50° F for the Key On Engine Off (KOEO) Self-Test and greater than 180° F for the Key On Engine Running (KOER) Self-Test.
Run it around to heat the engine up and shift thru all gears including Reverse.
Make sure A/C is off and transmission is in Park (automatic); or in Neutral for a Manual & release clutch.
Then turn off engine, all accessories/lights (close driver's door) , etc.
Do KOEO test First. Post Code(s) here according to KOEO & KOER.
Some no code usual suspects by Ford;
Vacuum leak, See my vacuum leak test in post #20 @ http://broncozone.co...de-44/?p=125535
One way to do a quick check is to grab a vacuum gauge. Bring the engine to normal operating temperature. Connect gauge to the intake manifold tee. BEWARE OF FAN, BELT, PULLEYS & HIT ENGINE.
The vacuum gauge should read steady between 15 and 22 in-Hg
One indication of a large leak is when air conditioned air flow comes out through defroster vents instead of dash vents.
Air filter, is it relatively clean?
Air inlet atop radiator support to filter box and to throttle body; look for obstruction; damaged tubing,
Fuel quality; Oxidized fuel often turns darker over time and may even smell sour. You can check stored gasoline by pouring some into a clear glass container and comparing it side-by-side with known fresh gasoline. If your old sample looks noticeably darker than the fresh gas, you have strong evidence the gas has gone bad.
Electrical connectors; inspect at coil, firewall, PCM, etc. especially those with broken locking tabs.
May need to test fuel pressure.
Bronco Fuel pressure:
Key on engine off: 35-45psi
Attach test lead to FP lead on self test connector. Make sure test lead is long enough to reach work area under vehicle
Grounding the FP lead at the connector will allow the pump to run continuously with the ignition switch on.
-Turn key to RUN position
-Ground test lead and read gauge.
