Tldi no start

[rcl700]

Well I just finished rebuilding lower unit and placed the motor on the transom of my pontoon. Hooked everything up ( fuel,batt.,tac. )

new 12 gal fuel tank and new gas from the station that day. Battery fully charged new plugs (autolite)

Turned the key first time > fired up and ran for about 1 1/2 min.(with muffs on) Then cut off
after that it will not restart

I don't know what's up.

Can the fuel be bad? (it came from BP that day)
I was thinking it may have run on the fuel that was in the lines and pump ( old fuel that was treated with sea foam before motor was removed) then when it got to the new fuel it cut out. Does this sound likely/ or possable?

How can I clear the fuel system of existing gas and start with new fuel agin?
Do I need to put sea foam in all my gas?
How can I tell if all cylinders are firing?
What else should I look at?
thoughts please. Spring is just around the corner.

Thanks guys.

Re: Tldi no start

You don't mention your model. Is it the 90 that you were working on earlier? What is the exact model?

Did you follow the start procedures in the owner's manual at http://www.tohatsu.com/tech_info/own_man_pdfs/Toh_40B_50B_70B_90B_115A_TLDI.pdf ?

You do need to force feed the oil (bleed the air) and fuel to clear any air that is in the lines. That may do it for you.

Re: Tldi no start

Update:
I drained all the fuel from tank & filters. Replaced with new fuel an still mo start.

I pulled out all spark plugs and cleaned them using a propane torch and a wire brush. Reinstalled plugs and gave it a crank.

Poof. It fired up and ran for about min. Then out and will not start agin

I removed and cleaned plugs agin put them back and it started agin.

I guess these plugs just can't hang.
I have ordered the ngk plugs. I hope they will solve my issues.

Re: Tldi no start

Are you flashing any codes from the tach?

Re: Tldi no start

no codes

I followed the manual on resetting after a bolted it up. it was beeping every few min. that was before i had a fuel tank so i had not started it yet.


after clearing, no codes.

pugs seem to get covered in oil and stop sparking.

Re: Tldi no start

That's a puzzle then...The tach will pulse a trouble code for virtually anything that is out of wack. So, it might be non DFI oil, incorrect sparkplugs, etc. Just to make sure:

You have a 1000 CCA battery
You re-set the TPS
You force fed the fuel pump
You purged the oil lines

Re: Tldi no start

put in the NGK plugs in about 20 min ago and they seem to have solved my problems

started it up an ran for about 10 min without dieing. it does have some sputters and small RPM fluctuations but that will hopefully go away after I can open up the RPMs on the lake.

Thank you all for your help!!! (pavnv & TOHATSU GURU)


until my next issue/problem

I will finally get to test out my new prop soon.

Re: Tldi no start

Plan on pulling those plugs out and cleaning them in 2 or three hours. If the old pluigs were fouling out you may have some debris on the top of the pistons that may shake loose.
