bike is in mint condition with 17000 miles, I will try all those you mentioned 1 by 1. Only thing is 1 was watching the voltmeter as bike was running and threw the code plus battery icon. Charging never dipped below 14.1 volts. Mind boggling.

 

Hopefully mechanical connection like the two switches or a contact pin on a plug.

Be sure to post back you fix.

I have s 04 Tacoma 4X4 with low milage purchased new. Once in a blue moon, I would get no fuel pump signal while cranking and a no start.

This year, it did it 3 or 4 times in a week. I took lower dash off both sides and the kick panels. It doesn't have a timer on crank side for fuel pump. It has two relays system.

Went through everything including frame grounds. Still don't know just how fixed it is however. I found the ignition switch off just slightly on the resistance side.

I pulled it apart and it's just a stamped plate of copper for the contacts. One was dirty. I cleaned it. I can only assume Toyota built it that way since it only controls relays.

However the want $180 for it. Ebay clone is 30.

 

well did a bit of searching and checked all ground wires, i did find a broken exposed wire on the hand control kill switch.. do you think that was the problem. Will ride it tomorrow and see.. fingers crossed.

 

Fingers are crossed.

 

If it wasn't the broken wire, I suspect RIPSAW is on point. Since you verified proper voltage, and saw it throw a code with proper voltage, it is probably a mechanical connection that is causing the ECM to see low voltage and throw that code...

Did you just inspect the grounds, or remove and clean them....??

If the broken wire you found isn't the issue, then I would start with cleaning grounds, and then I'd go to inspecting/cleaning the ECM connections...

Good luck and post back what you find....

 

I don't do this for a living but I just ohm the grounds to frame from the copper wire to the frame with my meter set to 200 ohm.

If there off any, then I pull them. Same for moving connections. I was surprised to see that the bar off was the first call out.

I never use that. Mine probably has not been moved in 18 years. Maybe I ought to flip it occasionally.

 

well fixed the broken switch wire and started bike twice and held my breath no code given. Took bike out for a quick spin actually covered speedo do i don't see it. 😁 after 15 minutes arrived home removed cover from speedo, checked for errors. NONE . MAN WHAT A RELIEF. So the exposed wire was actually affecting battery or was shorting to frame.
Whatever that's a relief.
Thank you all for your help.

 

Too cool. I added you to my friend request. Accept it so we can keep in touch.
