97 5.0 No crank

[banginheep]

I pulled the cluster out and the radio bezel to replace some blow or week lights. Through the cluster back in to check to see if the polarity was right on the leds and it wont crank. I was thinging the theift system, but its fine, only comes on when i lock the truck, no blinking theift light.
The only thing i can think of is the battery went dead while i was working on it, but its charged up. i even tryed a known working battery out of the wifes car, so its not a battery or the terminals.
So maybe kicked a breaker out or something. every thing lights up like it will just start right up fuel pump primes just no crank.

Drove it into the garage so the starter should be working.
So what do you guys think?

Isn't there an inertia switch? Or does that only turn off fuel?

There's a couple things that might have gone south.

Think I'd begin at the starter, jump power to the smaller of the two wires from the terminal of the larger wire -- id the starter turns over, the problem is not with the starter itself.

From there, move upstream to the starter solenoid mounted on the inner fender near the battery. Same thing, try jumping power to the smallest wire from the largest -- that will energize the solenoid and should then energize the starter.

Pretty sure from there, the next possible is the neutral safety switch -- if the PCM does not see the transmission is in Park or Neutral, it will disable the starter. Try holding the ignition key at the "Start" position and move the shift lever between Park an Drive. Be sure to have your foot on the brakes! If the engine turns over, perhaps the shift cable was knocked out of adjustment while doing the dash.

Lastly, verify the ignition switch energizes the wire to the NSS when you turn the key to start.

when you say shift cable are you talking about the cable for the shifter it self or the cable for the little pointer on the cluster?

I pulled the cable off from under the dash for the cluster, I dont know if the ecu looks at the cluster for park for some odd reason.

My own personal experiences working on my rigs is that when theres a problem its almost always the most difficult, frustrating, or complex problem lol so i completely skipped the obvious like the starter, starter solenoid, or any relay or fuse.

ill check them when get home hopefully its somthing simple.

ok have no power to the signal side of the solenoid when cranking so.
i tryed cranking it while moving through the gears back and forth nothing.

Ill try the nss this week end.

the nss wires are what color? i found a diagram that says its w/pk (white pink stripe?) and r/Lb (red light blue stripe?) dont know if thats right.
