93 350 TBI - Does it have a crankshaft position sensor - or just a camshaft position?

Not to argue, but a 6.5 will run all day long with the fuel pump not working. Killing the fuel pump on those ******** just make them LESS powerfull.

And x2 about them not working properly LOL

Ding! We've got a winner.. I took a closer look. It *is* in parallel.

I *suppose* you could say that, but I'm guessing it was more a penny pinching move so that the fuel interrupt circuit for accidents/fires had the same wiring runs for gas and diesel. You can oil-starve a 350 and spin a bearing long before it has zero oil pressure and shuts off the fuel supply.

Just sayin

As far as what I'm trying to do - just looking at my options. My truck faceplanted Saturday while towing - total power loss, random popping from the throttle body, etc. Cycling the ignition switch got it firing again, and it ran great all day yesterday (200+ miles at 75mph).

There are a million things that can cause the above problem, so I find it comforting that I can take CPS and CKPS off the list of possibilities, at least in the sense that the *function* CPS and CKPS would normally serve are taken care of by the ignition module/hall effect sensor on the distributor.

actually funny story you can spin all the bearings and snap a crank in 3 places in a 350 and still drive it home and it wont shut off.

By the way, lol, I figured out what caused the "faceplant" Saturday. I went to the auto parts store to replace a sketchy looking vacuum elbow. I was chatting with the folks who work there, and they suggested I pull the ignition module and have them test it.


No biggie, right?

I pulled the distributor cap and the rotor looked pretty cooked. Then I pulled the module connector in the distributor and it literally crumbled in my hand. Then I noticed the reluctor shield was loose. Then I noticed there were chunks of the reluctor tone ring laying on the baseplate of the distributor. Then I noticed the distributor wasn't locked down...

Holy C*##%t... I drove this thing from Colorado to Texas two weeks ago...


So... One new distributor later (changed in the parking lot and timed), and the truck runs great! I wonder how long it's been like that?


Ok. I'm a believer! It was tons easier to change that distributor out than I would have believed. It took 35 minutes from start to finish. These motors are freaking simple!
