Wire color on PGM for Honda Engine

My husband purchased a used Honda engine to go into a hovercraft, he was told is was a 1992 - however the wiring diagram doesn't match the wire numbers on the PGM.  also the wiring on the schmatic  doesn't match what is in the interior of the manual. 
Problem:  no spark.  If he turns on the fuel pump manually it will work but if its connected and is turned on with the ignition key it doesn't work.  When he turns on the pump manually you can see the fuel thru the line but no spark.  We are trying to figure out the problem and trying to find a correct wiring with correct color wires.  Can you help?

    Thanks, that didn't do it.  Because the schematic doesn't match the PCM, is there anyway to be sure of the engine year that we have?  There are two numbers on the side:  D15B8-1608477 and NP09A102.  Also is there a wire color code chart for the 1992?  Thanks ever so much for your help.

Chances are you have a relay problem. generally in normal operation when you turn the key voltage engergizes a relay that then closes the circuit which allows current to the fuel pump. now as far as no spark what do you have as far as ignition? is it coil packs or a distributor? have you checked the fuses to make sure they are not burnt. if you have a distributor lift the cap and crank the engine. make sure it's spinning. if it's not chances are it's a broken gear or tang on the distributor/ or a broken timing belt/chain or gear on the front of engine. now if you have coil pack it's the pack that is bad. make sure you are checking all your wire connections and the plug wires as well. hope this helps. please rate this solution.. Thanks and good luck

I have honda 91 and i get difficult to start up the engine when the weather is hot

the first thing that came to mind is the PGM-FI relay. These are really common in older hondas. It supplies power to the fuel pump, injectors, and ignition system. What happens is the solder joints crack and when the vehicle sits out in the sun all day the inside temp of the car is enough for those cracks to expand and cause an open circuit.

The relay is located up under the dash on the drivers side of the vehicle to the left of the steering wheel and almost right above where your left foot would be. It will ba a large relay and I think it is brown in color on that year. It will say PGM-FI main relay (or something simular) right on it. It will have a single connector will 6-8 wires coming out of it.

Once it is out of the car you can pop the plastic cover off and inspect the solder joints. You will be looking for what look like faint rings in the solder joints. I think I have a picture of a bad join. If you want to see it let me know and I'll post it.

What color wire should I tap on the distributer for a tachometer? 1992 honda civic cx

If that engine has an old dist with a coil, try one side of the coil, if that doesn't do it, try the other. If the coil is not present, but a coil pack, you will have wires coming out of it, besides the plug wires, one of them will do it, try the red one. make sure the tach is grounded and just check it with a test wire. It should go. Hope this helps.

Have a 1992 chevy g20 van. the van has a tv/vcr

you'd have to find out what colored wire is behind the plugged in vcr wire theres gonna be a black n red , or black n yellow ( something like that) the black is ground ( frame/body Connected) the colored wire will usually be the powered side. , then follow that colored wire to the fuse box and relocate that powered side wire to connect to another wire , down at the fuse box that powers up with the key on. just connect it to the appropriate wire. stereo shops or car dealerships can fix that issue real quick. normally for a few dollars.

My honda civic 1998 model fuel pump failed and I changed it

The PGM Main relay is outboard of the glove box. You can see it if you get the glove box out of the way, but to remove it, you need to pop the triangular shaped plastic trim off of the end of the passenger side of your dash. The relay is held in place with one 10mm bolt and the electrical connector.

1988 honda civic 1.5 l engine turns over but will not spark or run,new spark plugs,roter,and cap still no spark

well if this is the model i think it is you have pgm ignition. you have an ignition coil , ignitor unit, ground wires all(corrosion) left to check.
coil testing
  1. With ignition switch OFF, remove the distributor cap.
  2. Remove the two screws to disconnect the BLK/YEL front terminal A and WHT/BLU from terminal B of the coil.
  3. Using an ohmmeter, check resistance between terminals. Replace coil if resistance is not within specification.
  4. Check that the primary winding resistance between terminals A and B is 0.3-0.5 ohms.
  5. Check that the secondary winding resistance between terminals A and the coil tower is 9,440-14,160 ohms.
  6. If not within specifications, replace the coil.

unit testing
    1. Check and service any Honda engine codes before proceeding.
    2. Check the No. 32 50A fuse on 1985-91 models, or the No. 39 50A fuse on 1992-95 models in the dash fuse box before testing.
    3. Remove the distributor cap, rotor and the leak cover.
    4. Disconnect the wires from the igniter.
    5. Turn the ignition switch ON.
    6. Check for voltage between the BLK/YEL wire and ground. If there is no voltage check the BLK/YEL wire and ignition switch.
    7. Check for voltage between the WHT/BLU wire and ground. If there is no voltage check the WHT/BLU wire and the ignition coil.
    8. Check the continuity between the WHT wire and body ground. Service the wire or connectors as needed.
    9. Check for continuity between the BLU wire and body ground. If no continuity check the wire and connectors between the igniter unit and the
tachometer or the A/Trans control unit.

after these things let me know if problem persists
    1. If any tests were not passed, replace the igniter unit.
