I HAVE A 1993 750 ZEPHYR AND NOT GETTING ENOUGH VOLTAGE TO THE #2 SIDE COIL CAN YOU HELP

If your saying number 2 spark plug coil is getting no ground from computer when cranking, I'd have to check wiring connectors on both ends and do continuity test of the ground wire to computer. If everything checks out, check computer.

I suppose you swapped the coil from one cylinder to the next, to see if problem followed the coil?

You do have primary voltage going to coil, correct?

Schematic is included.

Did you do it like this? Voltmeter: black lead on negative battery terminal, positive lead on one of terminals on coil side- turn key to on, and see if there is voltage for about 2 seconds. If yes, check negative terminal of relay's coil side. If no voltage, move positive lead to other terminal for coil side. Turn key to on, and see if you have voltage for about 2 seconds. If yes, test negative side of relay's coil for good ground. If no signal at either terminal, the signal may be lost from the pcm.

When you turn the key to on, this will prime the fuel system-pump will turn on for only 2 seconds with key in on, and then if no crank signal, pump will turn off (the relay will not stay energized, so no power will go to pump). But when the engine is cranking over, the relay is energized, the coil side will stay powered as long as engine is cranking. After the engine is running, usually an oil pressure switch is tied into the fuel pump circuit, so the relay is no longer needed to put power to the pump. The pump will always be running when engine is cranking, and when engine is running, but the relay no longer is needed when engine is running. See?

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day and Merry X-mas.

onee of you carbs needle and seat is not closing all the way if you leave the gas on and remove the overflow tubes from each carb yuo should see this one leaking make sure bike is sitting up right so fuel isnt just running to one side

focusing on the coil packs but no mention of changing or checking the injectors or wiring to those injectors

Most likely the driver in the computer,that means the computer will have to be replaced,just check the connection at the computer to make sure it is good ,and tight,if it is,the computer will have to be replaced to repair the problem,sorry,If this was helpful,at all please rate,thank you.

hello,ok your fuel pump is working,hoping fuel pressure is also good,how about your ignition system,try to start your engine,then remove your spare plug,determine the condition, have fuel in plug?if yes try to check your ignition side,first check your excees voltage protection,located in fuse box(with aluminuim housing with fuse on top) ,,ty

check for presence of ac voltage coming from stator coil wire w/ a multimeter when you crank motor. also check pulser coil continuity.a service manual w/ schematics is recomended.

Hello Scott, remove the food from the freezer side and remove the rear freezer panel. You will see a coil and it should be completely frosted over. If not then you have a sealed system issue. If it is froze solid in frost where you cannot even see the coil, then you have a defrost issue. You should have a little frost on all the coil, the defrost is what clears the frost so the evap fan motor can circulate the air thru out the unit. If frost is good, push the light door switch to start the fan. If it isn't running check for 120 volts. If it has voltage, but not running, replace the motor. Hope this helps.
