EGR (exhaust gas recirculation) valve helps to reduce the exhaust emission of automobiles. It recycles some gases discharged from the engine by returning them to the intake manifold, where the engine can burn these gases again, thus reducing emissions.
The exhaust gas recirculation valve is located in the engine compartment (under the hood). Most engines need exhaust gas recirculation to meet emission standards. If the exhaust gas recirculation valve is broken, the car will not pass the exhaust. My Suzuki Jimny has had such a question before, so I am more qualified to answer this question

sorry nat, its no jeep.. (closest match here is Samurai)
moved yah i did.
No year stated, hopeless, for sure.. that...
nor is Jimny sold in USA, and this is a uSA forum.
Means we have no books on Jimny here...for that fact.
forget that lamp CEL?, it glows telling you , PCM has power and as a self test on lamp on all cars.
but the IMMO lamp? that be #1 to see... if fitted. as some are.

what matters only is this.. see how far you can get.?
won't start means nothing unless you say it cranks and don;t start.
starter motor sounds ok, not silent.?
see, we can hear this or guess. and is KEY to the reasons.

all you can do is test fuse.
see if cluster immoblizer light is glowing funny or flashing wrong.

dont crank ,? clean battery lugs, and then charge battery
jumper cable crank it.
cranks ok, check for spark.
if dont know how get tow to shop that does.

we dont have this engine in USA< (this forum is USA forum.....)

now to answer in GENERIC Mr. Otto Cycle mode. (gas engines)
no spark, check spark.
never tuned up, ever.
low compression, find timing chain slipped or worse.
twin cam 3 cylinder.
with chain drive. if chain is/was quiet, the cam timing should be good. as is compression over 150psi.
if compression is good, and spark good, x3
then it will run on test fuel, does it?
of not clogged melted CAT?

bulb gone?

double posted, back up 1

After searching on the net we saw a blog that said in rrsponse to having the rattle to ring the suzuki customer service hot line so we did. Found out that our jimny had a VIN number that was part of a recall that is still current. We booked in to get the rattle fixed at no cost they said for 12 Jan 2015. However today as we were driving along the steering column broke completely. We got the jimny towed to the same suzuki dealer and will be fixed free of cost next week. Moral of the story is ring Suzuki customer care and don't put it off!

It should be about 45 PSI at idle.

sounds like an electrical issue possibly caused by loose terminals or a loose ground check your connectors might be a cluster issue

Will the leaver not move? Try reversing a little, the forward. This might let it slip in place. Sometimes you get transmission wind up, causing the 4wd drive not to enguage.
If it won't come back out try the forward and reverse thing again.
I don't understand the light being on and your still not getting 4WD!
