Neutral safety switch/no start

[ssommerfield]

Ok, been reading threads all night while working on the bko. Have done all the checks, good starter relay, good ignition switch, etc. To make my question quick, does anybody know if a bad neutral safety switch will prevent power from going to the starter solenoid. Ignition switch is functioning, but i am getting no juice at the wire. I am hoping I don't have a break in the wire itself. Truck will start by jumping with a screwdriver, will not start in neutral or park with key. Tried to keep it brief, thanks guys. P.S. (5.8/c6)

That is the job of the neutral safety sw. If its not in N or P it will not power starter. Check the plug(may be loose), check the shifter rod going into the switch. Try adjusting the switch(2 screws mount it)

[ssommerfield]

Ok will do, read a good thread on adjustment, will try in the morning. Ive been doing what we refer to in the aviation world as shotgun maintenance, throwing new parts at the problem looking for a hit. Should have done more diagnostic before buying solenoid and switch. Thanks for the two cents.

You're SURE it's a C6? That would be rare. Read this caption:



Once you know for sure, edit your profile to include it. You can delete "19__" and "Bronco" since those are assumed here. Use that space for things we DON'T know, like miles, mods, damage, repairs, tire size, gears...

Then read these captions:

We call that "wasting time & money". I hope you kept all the old parts - they're probably better quality than the replacements.

A simple 12v test light works well. It will require a second person working the ignition. I think they are Red w blue striped wire one feeds into the trans and if not in the proper position (park or neutral) should prevent current from getting to the starter solenoid.

[ssommerfield]

Ha! yes wasting time and money is one way to put it. Crawled under the truck with a multi-meter and got 12 VDC going in and none coming out. Going to look at the adjustment procedure tonight and see if that gets me anywhere. If not does anyone have a source for a replacement NSS. No parts house in town can get them. I have found them on E-bay but the manufactures are foreign to me.

Unplug NSS and try it. Mine fell apart, ordered a new one with the wrong connector, drove it for a week waiting for the right one to come in. Mine starts in any shifter position without NSS plugged up.

Why would a 5.8 with a C-6 be rare? ....an AOD maybe....

[ssommerfield]

Yes it is no doubt a C6. I dont believe AOD was even an option for a 5.8. Tried the adjustment as outlined with no results. Bypassed the switch and back in business. New switch ordered and on the way. Have to have the rig for the beach this weekend. Thanks for the input guys.

Because the E4OD came out in '89.

Did you read that caption & look at the code? Is there an "O/D OFF" button on the dash beside the steering wheel?

Most every '89 Bronco w/ 5.8 that I have seen and read on here has a C-6.
Might have been offered in the '90....but I don't have a sales brochure. I was thinking it wasnt until '92. E4OD was for sure offered in the larger trucks in '90.

[Steve83]

It for sure was - read the bottom of this caption:

OK, but it wasnt offered in the FSB in '89. Bronco line seems like it always lagged behind the other lines in new stuff.

[Steve83]

AFAIK, it was, but I can't find anything that shows it definitively. This site (which is NOT authoritative or error-free) suggests that it was available both years:
89 http://www.fordpartsgiant.com/catalo...-18886685.html
90 http://www.fordpartsgiant.com/catalo...6-1900103.html
It correctly does NOT list it for '88, which suggests some level of accuracy:
88 http://www.fordpartsgiant.com/catalo...-18886685.html

[j. r. Nice]

I looked it up in the Ford 1989 Truck Light Duty Specification book FPS 12137-89 BOOK 2. January 1989.
The E4OD wasn't listed for the Bronco, only the 3 speed auto is shown for 5.8 vehicles.

[Steve83]

OK, so NOT rare. But I'd still like to see his door sticker, or trans.

[cnemo42]

can you adjust the cable shift linkage on a 1995 Bronco?

Need a little more help here. Have my problem figured out, bad NSS. Now, I have the old one bypassed so I can still drive the rig, but am having problems finding a replacement. No shop or dealer in town can get one. Found them readily available on e-bay, ordered one up and the connector was wrong. The original has 6 wires and a larger plug, new one has small plug and 4 wires. All my search for 89 with 351/C6 has returned the same four wire plug connector. Am I missing something? Is it possible it has electronic shift? I didn't think it was an option for a 89 C6. Thanks for the help!
