Running fine and it just stopped

I swear I posted this last night....anyway here we go again.

I had just finished installing my repaired radiator on my 1993 Range Rover LWB. The battery was dead so I put the trickle charger on her. The next day I went out and started her and let her idle. After a 15 minutes or so, I decided to take her for a test drive.

Everything was fine. Ran like I would expect her to. As I came home I guided her around one of the traffic calming devices and as I came out she died. No sputter just dead.

I got out and started looking for problems.

I have spark.
I tested the coil and have a nice strong spark.
I tested the distributor and have spark to the plugs.

I have fuel.
I pulled one of the lines on the fuel rail and have fuel there.

I have air.
I pulled the MAF from the air filter just to make sure I hadn't sucked a rag in the air filter.

I checked all my connectors and reseated them.
On the coil.
On the MAF.
On the temperature coolant sensor.

The last time I drove her I got an Error 17 (throttle position sensor). She still ran and I drove her once more after getting that initial code.

At this point though, she will crank but will not start.

Could the Throttle Position Sensor cause that? I thought I read that on a forum somewhere over the years.

How do I test the Throttle Position Sensor?

You might be onto something with the TPS. Mine was bad, and if I went past about 50% on the gas pedal, it would hit dead spot. The car would not die, but it would be as if I was not pressing the pedal at all.

I don't know any way to diagnose the TPS, and new ones are fairly pricey. If you do try to replace, watch out for the bolts that hold the TPS to the throttle body, these corrode and snap off, then you're left drilling them out.

Sorry this is not much help...

When you try to start, is the engine turning over?
