How to jumpstart a starter if there is no crank

Yup, but may not work on newest trucks.
My last truck with a DD15 would not fire the injectors unless the ECM was sending a start signal to the starter. Although if someone hit the start key at the same time you hit the starter with the screwdriver it may work.

 

Did you boost cars for a living, (or for that matter, a hobby,) before you became a trucker?
There is, or at least was, a Graydall in this area that has been used on more than one job site to unload trucks, when nobody else was using it.

 

That's fine as long as the issue is not in the solenoid or shift lever causing the gear shaft to not engage the fly wheel.

 

Fords "Better Idea" was to have a door keypad, key, and fob to operate the door locks.
Battery is dead, and key, with the fob, is locked inside.
Now what???
And did I say you can't get into locked hood to jump it?
You can't reach the starter easily, so I made up a rig like that and hung it inside wheel well - out of sight.
Had a alligator clip on one end to clip on hot terminal; jump from another vehicle battery to get juice
to the keypad to get in. Fooled me once; then my kid called with same issue.
So no worries, walked him thru it on phone and all good. He even put it back where it belongs. Amazing.

 

Here's something I do
I bought assorted plastic pipe splices and assorted clamps
About 10 bucks
Blow a water hose or airline and you can be back rolling in 10 minutes
A couple Winters ago I found a driver and his dog freezing at the Pilot outside St Louis at midnight
He had blown a water line the day before
I sent him in for anti freeze, by the time he came out his truck was fixed.
For less than 5 bucks.

 

had a plastic 3/8" air line melt thru - from the hot braided line directly from air compressor.
moved and secured braided line, but couldn't use truck without repairing tubing that was leaking.
Found a Lowes; and they had push in couplers that fit. Like you I kept some, and extra tubing, in truck.

 

Yeah, ya gotta be mcgyver out here
I'll take a taxi to Lowe's if need be to ad lib a fix.
Like I've told before, trailer blowout pulls your flap bar into the tires.
Can't move, 20 minutes left on your 14, a tire shop a mile away
Slide the tandems way back, tie a two inch strap from the bar to the Dot bumper, slide em forward
Flap bar good as new
Drive to the tire shop.
You do what ya gotta do.
