HaVe TrIeD EvErYtHiNg ThIs 96 DiScO wOnt TuRn OvEr

[robbyn]

I replaced fuel pump, fuel filter ECU (Fuel computer) Plugs, cap / rotor, wires, battery, fresh gas, dry gas, Swaped tps, Temp sensor out of my classic, also switched and tested my Air Flow Mass unit on the classic and it ran fine.

Took it to a local shop - they looked at it for three hours $150.00 and couldn't read it (only 1996 or newer) so off to Rover for the big bucks.... they have already told me that if my check engine light wasn't on that no codes would appear????? I question that and my check engine light never came on so am I as they say S--T out of Luck???

I have spark (blue), Timing, Gas too much it seems to be soaking plugs and flooding truck, don't know about air that is a hard. Will not start with gas off - With Starting fluid - Nothing!!!!

This has happens same time each year.... seemed when the temp fell below 30 which happened on the night my truck died. My truck was running flawless until I was searching for my dog at slow speed for about an hour 5 miles an hour after the dog was hit - I pulled off to the side off the road to talk to someone and put the car in park and then it sputtered and died, it started again hard(wanting to stall) when I put it in gear it was hardly enough power to pull it into the garage and I had it floored if I took my foot off the pedal it would almost stall. Once off the street it never started again.

I am at a total loss and so are the local boys... Rover got pissed when I said I just wanted the codes - that I had parts from my two other rovers and have worked on my own rovers since 1995 - I just didn't want them putting $1000 IN new parts into a 10 year old truck.

I would appreciate any help you have to offer -

Kyle I tried your suggestion in an earlier post cutting fuel off cranking, turning gas on - nothing....

Other post have no way of testing Amplifier Sensor - hoping rover can tell in morning.

Thanks

THE DISCO IS NOT A 1996 it is a 1995

The truck is a 1995

almost sounds like your ignition timing is way off. Did you check the timing by yourself, or someone else did it?

 

[RoverChic]

Do you have a Dissy? I cant remember if they do. Yes, just checked you have a dissy cap. Robbyn I sent you an email about the cap. Also, battery cables are they ok? Try this as well..

"For your battery concerns. Check your grounds. There is a ground cable going from the top bolt of the starter, straight over to the frame.
Specifically, it is on a body mount bracket. Pull that nut and bolt, clean the
cable end and bracket where the cable end contacts it. You have to clean it
real well. So it's shiny metal."

That was given to me by a LR Master Tech ..Have you tested the MAFS? Also lets try making sure this is really clean..Codes are under the seat passenger side ( I am sure you know that ..Just double checking) Good Luck!! Melissa N

Clean around in the plenum as well:

 

[Sergei]

Robbyn - does it crank up eventually? Does stepping on accel. pedal helps to start? Or it just turning over with no results? Do you have nasty smell after it finally starts?

Also - how is your starter? If it was caught up with engine once - bloody thing can still behave like its doing something but its actually torn..

Just throwing ideas at ya.

If you getting tired of hunting for Snark around Disco, you can follow same steps as i am and start saving for Rovacom-lite

 

[GregH]

I agree with Peter in that it sounds like static timing way off. I believe Disco went distributorless ignition in 96 so you still have distributor, right? And you're getting gas and spark, right?

Sounds like maybe timing chain popped a few teeth, or broken camshaft, or?

What do you mean this happens every year?

Did you quick check crank at 6 degrees BTDC and verify rotor is pointing at #1 post on distributor? If it is, try a quick compression check to verify cam is OK (or pull a rocker cover, crank over and verify valves working).

 

[GregH]

BTW-Have you checked your cats? If one went catastophic and plugged that may also cause your prob.

 

[Andrew Homan]

Fuel pressure regulator?

 

[Joey]

There is always a chance that you just lost one or more fuel injectors...if it is flooding out, I would say the injectors are just pouring gas.

 

[Rocky]

Do you have access to another 95 d1? Assume battery and alternator are ok
Wondering if the ecu has crapped out on you. That would screw up starting, result in no codes showing (display is under the passenger seat no computer needed) etc

 

[Kyle]

Yeah , if its happened yearly with that one I am saying its the same shit as I got going on here. I would also take the negative battery cable off and let it sit for a bit. Then crank it to get the flood cleared without the inertia switch plugged in and the throttle open. Ofcourse you could have an issue with the MAF. I am doubting timing and all the other stuff as none of that was changed and the truck was running fine. Keep it simple and you will find the issue.. Make sure the battery is nice and hot as you need some good spinage to clear it..

you need to get a hold of the workshop manual and follow each step in the book for trouble shooting a no start. Then you keep narrowing it down.

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. I once had a corroded connection there and it resulted in a similar issue.

Rover Called The Verdict Is In!!!!

Believe this or not... 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!

$500.00 later all I need is a ignition coil - which I have a temp one out of my 1991 classic but would like to get without 140K on it - anyone know of a place where I can get good price on coils.

Thanks everyone for your help You'll never know just how much I really needed your advice and suggestion - I think my truck had the best overhaul tune up of its life!

Robyn: Must have been thinking about your problem this afternoon. Was about to write to you to suggest COIL...but you've done well....Good job!

 

[Kyle]

You may want to check the coil connections as Rob suggests. Sometimes those little slip ons arent making the proper connection and jsut need to be crimped down and cleaned up. Try the one off the DIsco on the rangie and see if it starts.

[Steve Rupp]

That's a good idea. If the truck does get started, DO NOT wiggle the connections. If the coil wire has a bad connection, it will arc to the coil and you do not want to be in the middle of that. Believe me, you will get lit up worse than sticking your hand in a light socket!
