NAS 110 woes

After driving my 110 for months with a very soft start (It would start after a 6 second crank, of if i gave it gas about 4 seconds in, or on the second crank) it would start. Now it a non existent start.

Fuel is running through the lines at least past the filter (no idea about the pressure). I thought it was the pump due to the soft start. I am focusing on the fuel aspect, but it being dead could be totally un related (still Cranks). I could have it towed to a mechanic. but want to exhaust my options.

I place great faith in this forum since getting the advice (after failing emissions) to just use a fuel additive, IT WORKED.

Any thoughts would be appricaited.

One more piece of info, The 110 was running/ warming up, I went inside for about 10 min, when I returned it was not running and would not restart. Still thinking its a Fuel thing.

Friend of mine is having the exact same problem on his 95 NAS. We replaced the ignition coil seem to fix it. Worth a shot for only $60

You can get a fuel pressure gage from an AutoZone for free. Hook it up to the schrader valve (same thing as a bicycle valve) on your fuel rail. If you take your bonnet off, you can see the gage as you turn the engine over to see what pressure your pump is putting out.

Have you checked fuses, relays, the easy stuff?

replaced all fuses with those one that show a led when a fues is blown (tiered of always checking fuses when trouble shooting) and Crank is strong. But it would not have turned off once it was on.
I thought the same thing when it was just the soft start.

Check the fuel return to the tank. If there is fuel returning to the tank then it should have sufficient fuel pressure. There is a valve on the fuel rail that regulates the return. That valve is pressure activated to open when fuel pressure to the injectors is optimal.

If there is fuel coming out of that return valve, fuel pressure isn't likely to be your issue. I'd look to ignition then.

Sounds like symptons I used to have with my 95 Disco.

Briggs gave good advice.

Are you getting spark?

Here is my 2 cents. Pull cap and rotor. Gently clean all contacts and rotor tip with emory cloth.
Mine would fire right up.

Keep us posted as I never dove to deep into the problem because it always started. When I first bought it I sent it into my guy and mentioned the soft start and they replaced plugs fuel filter and some other much needed things and when I got it back I was looking forward to not looking like white trash at the gas station when filling up and having to crank it so long but, but still had the soft start.

Ok, to keep responders posted it was the distributer rotor!! And un related to the soft start which I still have.

BUT I just replaced this not 300 miles ago. Whats up with that. Did I do something wrong when installing. (no because it worked at least for 200 miles). I will keep an extra in the truck just in case.

Would appreciate any thoughts on why that would happen.

Some, or maybe even most, of the available "distributer" rotors are said to be cheap crap from China. Which/whose rotor did you use?

I ahd same issues, as I stated. Even the LR Genuine part failed.

Store some emory cloth and your old cap and rotor (already burnished) as spares in the truck.

Just for fun, now you have cap and rotor reinstalled, with truck off grap cap and see how much you can twist it side to side. Don't break it, but you will prob see a ton of play.

Ensure timing is set as this will def affect start.
