I went out to get in my 2000 Disco and it would turn over but not fire a lick. Tried for 15 minutes. Got a ride home and had it towed. Went out to work on it and it fired right up. Any ideas?? I wish it had not cranked so i could have found the problem. Now i am scared to drive it.

 

do you run good quality premium gas? It could be your crank sensor about to go out. don't try starting for more than 20 seconds at a time or you'll burn up your starter.

 

How many miles on it?
When was the last tune up?

 

I run 89 and 91 in it. It cranked this morning and i drove it about 5 miles. Got in to go and would not crank again. It has 121000 miles. had a tune up about 3000 miles ago.

 

Sounds like a crank sensor about to die.

 

You need to be more specific in the future, your engine does"Crank Over", it does not start, there is a difference.
As AK has mentioned, it is most likely your crank sensor.
At your mileage there should have been a full service done,including new plug wires and 02 sensors if you plan on staying on top of any up coming issues.
As for your fear to drive it, you should be cause if it is the crank sensor, it will just get worse to the point of not starting at all.

 

Well it cranked up run about 3 minutes and died. this time though it set off the check engine light. Hooked up the code reader and there it was P0335. So with that said is this a part i can put in without needing the dealer to reset or program anything? Would like to keep the bank robbers out of the picture if possible. By the way THANKS for the help so far.

 

Sure, you can do it, order the sensor from a local auto parts store fpr $65 plus and one of use can walk you thru installing it.

 

you need to run 93 octane only

 

I am going to LR Monday morning and get it. So if you could go ahead and give me some help would be great so i can do it as soon as i get back Monday. Thanks so much for the help.
