JD 445 no fire to the plugs and no fuel from the injector I tried another used A-1 coil checked all relays according to Tech manual all fuses good no broken wires

Does it have good spark at plugs, good fuel pressure to injectors and injector pulsing, good cylinder compression ?

Check fuse 1. If fuse is good, problem may be the PGM-FI main relay. This is a double relay. See diagram below. During start, one relay closes. After start, the other one takes over.

What make , model an year vehicle ? Could be a relay problem , power hold relay for ford , ignition 1 relay for GM vehicles or ASD - auto shut down relay for jeep , dodge , Chrysler vehicles . Asian vehicles have them too , Honda - main relay powers fuel injectors , coils etc.... Do you know how to do basic automotive electrical testing ? Check for voltage ? You would need to look at a wiring diagram for your vehicle , see which wire powers the coil an injectors etc...test for B+ voltage ! Videos on you tube showing how to test ignition , fuel etc..

Can you rev it up when its parked ?
Have you checked base fuel pressure with a gauge ?
Did you also replace the fuel filter ?

When you say you have fuel, do you have normal fuel pressure at the injectors ? Because Honda cars are known for faulty fuel pump relays.
The relay stops powering the pump when it gets hot but will start back up when the relay cools off.

This is a long shot, but maybe the fuel pump relay or pump is shutting down when it gets hot. It sounds like a fuel problem to me. Good-Day! Hope this helps! also check and or replace fuel filter, and air filter.

Check to see if there is power to the injectors. They are fed from the same fuse and relay. If there is no fuel pressure than the fuse would be the fist suspect sin the ASD and fuel pump relay are fed off the same fuse. The fuse is fuse 21 in the power distribution center.

If the fuse is good try swapping the ASD relay with another relay in the fuse block that is the same. If you know have spark than replace the ASD relay.

Normally we start with the basics, are the spark plugs firing and are the fuel injectors opening and providing fuel, and does the engine have compression.
Also, are there any stored trouble codes in the computer?
There is a relay that powers the injectors and fuel pump. You say you are getting fuel so we will assume that relay is ok.
The crank or cam sensor could have failed, or a list of other things.
You will need to figure out if you are lacking fuel or spark to the plugs to proceed.

Air - not likely the problem ! mechanical cable controlled throttle body

Fuel- make sure there is gas in tank! fuel pressure test at the throttle body or rails, if no fuel check power to fuel pump: ignition power to breaker or fuse, relay , power to pump at 3 pin connector near tank/frame rail on drivers side, - if pump is runniig but insufficient pressure, check for mechanical restriction: plugged filter broken or pinched line, plugged pickup tube in tank. if good pressure to rail or body, check ecm : diagnostic codes, fused power, ecm tells injectors when to open, dependent upon several sensor parameter inputs.

Spark- ignition - coil-distributor-ignition module (or coil packs)- wires-plugs-ignition module (signals coil to discharge, mounted beneath distr cap) work backwards from plugs.

Have you checked the cam sensor. It coincides with the crank sensor to tell it to fire . And it controls the injectors.
