I have a 96 Disco it runs good and everything works okay. But when i driver around an 1 hour and stop turn it off and they turn it on agian it will driver good until it losen power on the gas and if i step on it it will backfire and wont move?

I need help to see what is wrong with it i already checnge the fuel filter.

 

Probably a good time to check the fuel pump pressure, there is a valve like a tire valve on the passenger side fuel rail, expect 32-34 PSI there with truck running.

If problem only happens when truck is warmed up, may want to check the crank position sensor, back of engine, driver side; you can pour cold water on it to cool it off. It will eventually get so bad truck won't crank.

Check engine light on? Time to read codes.

 

okay i will go ahead and try that. i will let you know what happens and i will see what codes it has. I so ahead and put cold water on the crank to see it helps.

Here's a pix of the sensor, this one is on a Discovery 2, but same area. The wire leads down to that box on the engine, which covers the sensor.
