No start only click 2.5na

Help, please!

My 86 2.5na is not starting. It will click only once, but no crank. Push starting works. Connecting directly to the starter works.

Have a new Lucas starter installed, to no avail.
Battery was holding charge just fine. Have charged to 100% just to be sure.


Suggestions?

Do you have a remote solenoid or one on the starter?

Make sure that the ground strap / wire from the chassis to the engine is making good contact.

I have one on the starter, so it's new as well.
The ground wire is a thick gauge mesh wire that is clean and connected well on both sides to clean contacts.
Thanks,
Ridwan

And the Battery Ground is good too?
I am assuming your battery is under the LH seat and grounds to the chassis.

Yes, both connections to the battery are clean, and the wire and connectors in good shape

------ Follow up post added October 12th, 2015 02:45 PM ------

I am assuming it is what I hear clicking, but where is the starter relay for the 2.5?
And does this have a "starter inhibitor" or is that just an automatic thing? (Mine is manual transmission)

You should have the + lead from the battery going to the starter solenoid attached to the starter. the small wire on the solenoid should go to the ignition switch. If you take off the small wire and make a jumper from the solenoid and touch it to the battery + it should start.
I am not aware of a relay for the starter.

@TRG: Have done this successfully.
Does this mean the solenoid is faulty?

Anyone have a photo of how the solenoid is wired? I wonder if I have out wired incorrectly.

Bridged the brake check relay, and she starts. So, no starter relay, but yes brake check relay in starter circuit to cause similar havoc. Bonus, new starter and I'm off to find a relay.

Been following this thread as I have a similar intermittent problem on my 90. Every 10 starts or so, I get a click (which I believe is the brake relay), but no start. A few turns of the key and all is well. I cleaned and/or replaced ground straps & battery cables, replaced the starter and the problem is much less frequent, but still occurs.

How could the brake check relay affect starting? According to the schematic, on my '85, the relay is parallel to the start circuit from the start/glow plug switch. Thanks.

Some trucks have start relays, some don't.

The brake check relay is also powered during the cranking by the start wire. It is designed to simply turn on the brake warning light so that you can see it is functioning. I guess if it shorted out or something, you might lose enough voltage to prevent the solenoid or start relay from engaging.

Attached is the civilian 2.5NA wiring diagram.

74 - Ignition switch
64 - Starter
54 - Brake Check Relay

WR (White/red) is the wire to teh starter solenoid that turns on the starter.

Thanks John. I was looking at that diagram last night after reading this thread. Good point that the relay may be pulling enough voltage to affect the starter solenoid's operation. I'll have to bridge the brake relay and see if that helps.....need to find it first! It is not with the fuses on mine and I think it is under a plastic cover on the engine side of the firewall or behind the instrument panel. I am installing a new panel and binnacle this Winter so I will get to it eventually...

When you find it, just pull it out. That should stop it doing anything bad. It is only there to allow you to see that the light is working. I'm not sure where it is on the earlier trucks.

I wonder if this is why the military truck have a start relay as well, to ensure the solenoid gets full juice.

Location in mine is behind the interior fuse panel (inside passenger compartment, behind the plastic cover) it was the second one in, just next to the flasher relay, which is furthest outside.
About it being parallel--yes, that's why I didn't check it earlier either! But guessing that it's happening because of reasons mentioned above. I actually didn't try to start without it--will let you all know results when I do.

Does the 2.5 have the same key tumbler assembly as the 95's. If so, mine did the same thing,*but it was only because that tumbler was not completely apart yet.

Rick, explain a bit more, please?

Anyone know if it's the same tumbler?

Ps. No start without brake check relay present.

That does not make sense. Are you sure it is not a start relay? Some trucks have a start relay.

If there is a start relay, what would out look like/where?

@red90: It doesn't make sense. Tried bridging red/white and black/white again, and no start, only click. Must've been a fluke that it worked last time. That's happened three times so far--truck started, that is-- in the last 50ish tries.

Only flashers and brake check relay behind this fuse panel.

I had exactly the same issue on my ex-mod - it started after media-blasting. I switched relays over and it worked so blew compressed air and some contact cleaner into the non-working relay behind the fuse box and it's been fine ever since (touch wood).
