NAS 110 Won't start after snorkel

I just installed a RN snorkel under the driver side wing, under brake booster, over tranny and up to air box and now it won't start. The engine turns over no problem but just won't start. I checked all the wires on alternator, coil, distributor, under wing, all over...I feel like I must of tweek a connection while I was running the snorkel hose through the engine bay but did not find anything loose. Any thoughts of what else I should check. I also noticed that when I turn the key the tach stays at 0 and doesn't move...is that normal?
Thanks in advance,
Ed

Wild, wild guess. Does a NAS 110 have an inertia switch?

Inertia switch should be on the center of the bulkhead. You may have bumped it or knocked a wire loose running the tubing.

tach reading zero could mean in your fidling you pulled the signal wire on back of alternator.

This def sounds electrical. You missed something..

Check the electrical connections to/from the coil and ignition module/distributor

Mike I checked these multiple times.

I will look for the inertia switch. I am not sure what that looks like but hopefully it looks like the one on my DI. I think this may be the culprit. I will report back.

Thanks and keep the suggestions coming.

Didn't disconnect the MAF. I could not find the inertia switch anywhere. Anyone have a picture showing where it is?

Step 1 is pull a plug and see if you have spark.

The inertia switch on a 1994 (3.9L) is near the fuses inside the cab. You can see the button on top of the unit. I don't know if the 110 is the same as the 1994 or not but I assume so.

Rovertrader has confessed to having a laminated NAS 110 parts manual. You can check with him.

Rudolph Diesel is my damn hero. I don't miss this ignition BS at all.

Before you go chasing your tail..see if you've got spark...if no spark it's not your inertia switch..

If you have a remote ignition coil my money is you unplugged it while routing the under wing hose

What? And then remove the rag he put into the hose to keep foreign objects from getting inside the engine?

As people suggested back to basics. See if you have fuel and spark. Works even with EFI.

Did Mantec get around to introducing a snorkel for the Rover V8? Last time I looked (a while back) they only had snorkels designed for the air requirements of a 2.5L engine For a 3.9 it would be restrictive. And since air likes to go down a tube in a straight line your bends might just cause a little turbulence and slow the air flow down.

That's why I got rid of my Mantec and switched to Donaldson air filter system. Filters really well and has plenty of airflow for my engine.





Anyway, as people suggest, first the basics then get out the error decoder to see if the computer can tell you what went wrong.

Found the problem...it was a plug that goes from the coil to right below the disturbutor see plug 1. It has 2 white wires and split loom tubing in pic. It's slightly loose and when the engines is on and you wiggle the wires the engine shuts off. I need to replace that wire connector. Anyone know what that is called?
Thanks everyone for your help in trouble shooting this. I found out after I checked for spark.

Glad you caught it. Mine was loose on my Classic. A gnat could have landed on it and shut the car down. I just squeezed the contacts together to tighten them up and haven't had a problem since.

That is the plug for your ignition amplifier module.
