My '88 ranger 2.9, manual, has been suffering with a cranking issue.
I turn the key, the lights go out like they do when it starts, the starter does nothing. If I leave the key on in neutral I can jump the solenoid and it fires right off.
This started last spring, I suffered with it for awhile, changed the solenoid, bat terminals, etc. Out of the blue it started working with the key, went that way until I parked it under cover for the winter. This spring, same deal, won't turn over with the key.
Everything in the column works correctly, I cleaned the main loom connection under the hood, pulled and checked the supply wire for the starter and it tested out fine. Cleaned all the connections I can think of.
Once it cranks everything works as it should.

What am I missing?
Thanks
Rich

Manual or automatic?

Both have a "neutral switch" which must be CLOSED to pass "key in START voltage" on to starter relay(solenoid)

Manuals have a Clutch pedal switch, clutch pedal must be down all the way
1988 Automatics have an NSS(neutral safety switch) on the transmission, shifter on transmission must be in Park or Neutral

I assume you have a manual from the "I put it in Neutral" comment
Clutch switch is on the pushrod on the clutch pedal arm, could just be loose

You can also bypass the switch, google: Ford ranger bypass clutch pedal switch


Power path
battery---------ignition switch in START(12volts)------------clutch switch-------------------"S" post on starter relay(solenoid)

Lol Ron, its a little of both...
Its a converted manual with an auto brain, so it has both the clutch and neutral switch.
The interlock has crossed my mind, that thing is a p i t a. I'll have a look at that :icon_idea:

Thanks,
Rich :haha:

I went through the YouTube stuff, did the bypass for the clutch switch, no joy there. I have a new solenoid, will put that in and a main wire to the starter since I have one of those and go from there.


Thanks

New solenoid was just a new part, no change.
I've jumped the clutch switch, neutral switch.

There is power from the switch, none at the clutch switch.
I put in a button to the solenoid. At least now I don't have to get under the hood every time I want to start.


Strange coincidence?
My neighbor just had the same problem arise in his newer Dodge after a clutch rod issue. He installed a button too as we couldn't trace the issue there either.


I'll bet this is silly stupid to fix, I just ain't seeing the solution.
Any other suggestions are welcome.


Thanks
Rich
