Question about 2000 Suzuki Grand Vitara

2 Answers

I Changed the harmonic balancer on my Suzuki Grand Vitara 2000 2.0l J20A. Why no spark now?

Changed the harmonic balancer on the Suzuki but in the process the key way piece fell out so had to put the timing cover and chains off to replace it and to set the timing marks. I followed the instructions that were given to me by other fellow fixya's thanks for that, although with the timing instructions it says that there are blue marks on the chain but there wasn't, but I am still pretty positive that the marks are in the correct places. Put it all back together and now there is no spark at all. Motor turns over but nothing. Any ideas on the problem would be really helpful as I don't really want to pull it apart again if possible. Nothing comes up on the dash to indicate a problem.

First off the J20 CKP (crank) sensor is buried deep behind the fly wheel. (so, if still plugged in, it will work) any SCAN TOOL tells you if its dead. and CMP, cranked for 5 seconds.......all do. but dont......
and the CMP on this twin cam, is at the left rear of head. left cam driven. (rear)
did you play with this cam sensor, i bet not. its not anywhere near the chain at all... so....????
and the engine is interference, and we never crank them
with out checking the timing for perfect correctness , the missing color chain, leaks may mean car has aftermarket parts in it... or oil when acidic and eat off the color (it's blued like guns are. those links, so.....) guessing here, is a travesty on most DOHC engines.

if you run this engine with no keys, you will bend over the valves.
proof.: (safe , the only safe way, keys in pocket)
do a cylinder leak down test. now, (by hand) i bet it fails.
hard. the tool needs shop air, got air?

Any one doing this should read every word in the FSM on topic first before playing
with any DOHC engines. or it might be a total loss..
read the engine ,page, read allsteps under, new chain.

sorry for having to state the truth of topic.
read up on DOHC engines.. I have one that is free running from Mazda. but is an exception to the rule.

good luck

here is a G16 getting done.

step by itty bitty step.

the good youtube link is there, most are not good on youtube.

    the crank trigger only allows the OBD2 spark monitors to work, the CKP sender allows car to start. (try this) the scan tool will in fact report all CMP errors 1 in 10. and a all dead ones. cranked for 5 full seconds, try it. and the CKP is behind the flyweel (trans must be remove) and not located at the chain he mis-timed.

Suzuki grand vitara (J20A) and error code P0340. What is it?

p0340 is indicating a problem with the CMP sensor .. thats "camshaft position sensor" ... the 340 would indicate that the sensor is open or shorted (not giving information) ... look for disconnected or defective CMP or CAMP sensor ..
