I have serious engine issues was created by chewy
Hi, i have a 1999 jimny, a month ago it started to loose power, now all it will do is tick over.
it will not rev at all.
Checked:
plugs
ht leads
throttle linkage
cat

the garage say their diagnostic will not talk to it and they suspect the ecu.

can anyone shed any light on this before i spend a load of cash on it.

Cheers for any help.

Mike.

You say you have checked the CAT, but this problem really is symptomatic of a blocked CAT.

I would disconnect the exhaust at the manifold and see if it runs better (but very noisily!!)

The other issue might be the Camshaft sensor, these fail regularly.

Not sure why the ECU won't talk to the diagnostic system but I would have thought the engine would not have run at all if the ECU was stuffed.

When you say it will not rev ... if you try and rev it, does the rev counter / Warning lights / speedo go crazy ?

This sounds similar to the symptoms ours showed when we had a sensor breaking down.

Could be driving at 70 mph, all of a sudden, back fire, foot flat to the floor and nothing .. dip the clutch and it would idle no problem.. rev it up and the rev counter / warnings would go crazy.
Switch off and allow to cool / restart ... no problem .. until it got warm.

at 5mpg in low box it would go all day but as soon as you revved it ....

Replied by chewy on topic Re:I have serious engine issues
Just had the garage on the phone AGAIN, The problem is the crankshaft pulley bolt has sheared, the key way is so worn that even if they got the remanence of the bolt out it would still be loose on the shaft so the only option is to try and weld the pulley directly on to the shaft.

Unless anyone has a free engine on offer?

No i didn't think so.

Hope no one else has to go through this as it is a real ball ache.

And as for the engine management code readers , nope, most of them dont read jimnys, ive tried a few including Snap On and finally had to go to the auto electricians in Crewe and pay £50, they gave me the code, read the workshop manual, fixed in half hour for nothing, oil in pipe to sensor.
I couldnt read my last T reg one, cant read my current S reg one, and couldnt read Mavericks 54 plate one, just comes up with 'import' on one reader.

I have had two or three code readers and they all read the codes ok on my 03 plate. They didn't display the diagnostic reason, just the nummeric code, which you then had to look up in the manual. The Code Reader I currently have is permanently connected (see www.bigjimny.com/index.php?option=com_co...accessories&Itemid=2) and it works well apart from the US gallons issue.

Only a Suzuki code reader can read the Airbag and Immobiliser codes however.

Thats interesting Martin, the Snap On one which is near new and cost a small fortune just comes up with 'no codes found' on my S reg and my old T reg, and on Mavericks 54 plate it came up with 'import', referring to the manual it states its unable to read it as it has a foreign code in place... ??
My friend has a local garage and he has 2 code readers, ones a scanner, the other a full ODBC scanner and reader. neither of them work on any jimny thats been through the garage. the Snap On one belongs to another friend who works at the other garage in the village.
So, what model code readers do you have Martin, and what codes have you been able to read with them? have they helped or just come up with 'no codes' like my two cars?
I have done the 'short the plug out and count the flash' method which pointed to the right sensor on the fault i had on my old T reg one, but didnt tell me wether the code was 'high' or 'low' which means either sensor is knackered, or reading from sensor is wrong....

I currently have the Autel Maxitrip which displays the error codes..

Here it is telling me:

Fault 1: P0105 - DTC P0105 (DTC No.11) Manifold Absolute Pressure (MAP) Circuit Malfunction

Fault 2: P0335 - DTC P0335 (DTC No.23) Crankshaft Position (CKP) Sensor Circuit Malfunction




Before that I had a ELM SCAN 3.12 and we also used a "yellow hand held" that a mate had.

See www.talktomycar.co.uk for the Autel one that I currently have.

Thats pretty cool Martin (other than the errors its telling you lol!) Someone on SS just said that a lot of the cheaper scanners are known to read suzukis.

Its pretty cool telling me all sorts of stats, including temperature etc. its just a shame that MPG is in US Gallons ot Litres. According to "Talktomycar" (a UK company) there is no call for one that works in Imperial gallons.
