Things that can keep a Disco from starting?

[DiscoEd]

Hi,
I thought I would try to get a concensus on all the things that could possibly keep a Disco from starting and the symptoms associated with each.

For example: Will the crank position sensor keep the engine from starting and what are the symptoms? No spark? no fuel?

I thought if I could get engough good info I could compile it all into one document and the circulate it around. It might be helpful to people when they are struggling with their Disco.

Thank you,
DiscoEd

I think you are talking about compiling a book as thick as the chicago phone book.

what you are describing is Kyles living room...and you are standing in it

You may be right, I may be crazy, but this just might what were looking for!

Thanks for the laughs Musky!

It guess what I'm driving at is that there are a lot of good bits of info floating around out there in cyberspace. The problem is that they are just that... Bits!

I'm not saying that I propose to write up some super detailed service manual (as nice as that would be) but just to collect up some of the simple (but effective) ways to narrow down and fix problems. Don't get me wrong the forums are an awesome resource, that I'm thankful for, but sometimes gleening info out of them is like finding a evidence of water on mars.

Quite often on the forums the questions are present, the suggestions are present, but the final solution is not. There are plenty of owners lurking around out there with this knowledge. So maybe it's time for them to pony up and give a little back to the community. I'd be willing to compile some of this info into a PDF, text file or whatever and make it available.

Thanks,
DiscoEd

Ed, You didn't get the truck running yet did you?

 

[DiscoEd]

Nope not yet...

Str0ud,
That's an understatement!

Truth is I've been so busy with other things this week I really haven't had much of a chance to continue my quest. I'm hoping to tear back into it this weekend.

Thanks for the smile!

Something like a New Owner Tips section that is easy to find. With the most common issues that new owners should check first before posting anything.

Sergie, oh Sergie where art thou??

Fuel pump, Fuel pump relay, bad 02 sensors, dirty MAFS, Coil Pack gone bad, Dissy, ECU, Spyder Box issues, bad ignition wires...Just to name a few

 

[Sergei]

Lots of stuff can prevent it from starting. Some stuff can prevent it from cranking
Which one you like?

Usual causes:

No start/no crank - MAF(?), coil, battery, bad grounds, starter dead or rotten wire to it.

Hard start/slow crank - no juice in battery, MAF, TPS, coolant or fuel temp sensor, leaky injectors, worn ignition components (wires, plugs), coil, bad grounds, fuel pump, fuel filter..

Then of course there is stalling with restart, stalling with no restart, blah blah..

Stuff like that.. Those are typical causes, of course. Other causes are much rare to list

My kids were playing with my keys the other day. Lost them in a pile of toys.
I'll be damned if that Disco wouldn't start at all without those things.

Since when would a bad MAF and/or coil keep an engine from cranking?

You are fucking kidding me right?? If I do not turn my key with the right amount of love sometimes the Disco will refuse to start.

It is all about the LOVE!

Exhibit A

I'd look at the coil. Classic symptom of a coil thats leaked coolant and overheats as a result but driving ensures "splash" lubrication keeps it cool

Exhibit B

the coil is working but is not working strong enough...

It was the ignition coil - it came up on the computer - the tech went out and pulled one off his 95 and she fired right up!

Exhibit C

Have you replaced the Coil? If so are you sure it's putting out the proper juice?

I had my amplifier go out on my rangie rover and following the book pinpointed it. I was in disbelief until i plugged the new one in and it worked. ALSO MAKE sure that the wires traveling from the coil to the MAF are plugged in and grounded.

OK I am done for now...I hope that I addressed your question accordingly!!

Wow! Such language from a pretty up and coming lawyer lady!
Have a hard night?
I agree with PT, a MAF will not prevent a motor from cranking, it may prevent it from starting though.

You are very protective of Sergei. Maybe you're dating the wrong guy?

That is nothing RoverHound..See me when I can't get the Rover to start...Now that is a sight to be seen!?! LOL ~ I am stressed about the Pageant gig today!

Name of the thread was "Things that can keep a Disco from starting?" Maybe I should have re-read PT's ?? more accurately. Nonetheless, no starts can be linked to ALL of the aforementioned.

For the record I am not dating anyone.... Sergie has more knowledge about no starts than RovaCom. Lastly, would I not be a law kid if I did not have a niche to defend??

Trust me. I've been talking to her on her cell phone when her Rover won't start, and it ain't pretty

The engine in a Disco is no different than any other gasoline powered engine. If your engine doesn't start it can be at least one of three things not happening.....compression, fuel, or spark. If you have all three, you have a running motor.

Cool, Big Ed is back.

 

[Sergei]

Yep i screwed it up, Paul. I tried to copy strings and didnt edit things enough. You right and i am wrong.

Of course coil cant prevent you from cranking. Nor can really MAF.. i just been thinking about few different things when was pulling that message.

Btw another thing that can prevent you from starting is inertia switch.. Another popular cause.
