The Usual Post About Running Issues

[fixkick]

Hello Fixkick,

Great site you have here. I'll be around a lot more as I just traded my Samurai for a Sidekick. Mechanically savvy, but new to vehicle electronics.

I've been driving this 95 Sidekick JX 4 door 1.6 16 valve California Emissions for 2 weeks without a problem. Drives like a dream. Previous owner (reputable member of the Suzuki community) also had no issues with it.

First day I had it it threw an EGR code for and hour and then went away so I didn't worry about it.
this is a thermal sensor inside the EGR main, called EGRT.but if need be we can fool it with a jumper resistor 10k ohms , ask.

The issue now is this: Took it to exhaust shop to get new exhaust. It's been welded and re welded 50 times over. It's been running without a catalytic converter for I don't know how long, so I was going to get one installed.
DID YOU>? EGR flow rates will not work with no cat. so... fixing EGR with no cat is a wasted effort.

The mechanic started the car the next day and got the engine warm to melt snow off the vehicle.
When he came back outside the snow was melted but the vehicle was off.
Now it wont start back up.
It cranks and fires but there isn't even enough to to give it the gas pedal to see if it will stay running before it dies.
so sparks ok, are the spark tips black or white. if black then its rich and fouling spark plugs
if white, then you lost fuel pressures, or MAP died, or air leaks to the induction behind the MAF


I personally think the EGR valve is clogged based on what I have read here and the fact it has been without a converter for so long. I may have wrote off the EGR code 51 earlier, but maybe there actually was an issue?
This is not it. The egr only your is dead, 2 ways, packed in carbon, long ago and CAT kills the rest missing.
Then engine can run fine with no CAT or EGR, but best is to fool the EGRT, ask. so the ecu does not go to limphome. (cal cars might)

Let me know what you think. A bit upset as I just wanted the exhaust to be done today, but now I gotta go and diagnose this thing in this guys lot after work instead.
sorry for you loss and pain, no fun stranded or working in field lacking a shop full of tools.

Thanks.

if it were mine like this
spark plug out. black,? put in a new set gapped at .028" and drive home
if it will not run at all, try test fuel, to see if the engines ok, i must run on test fuel. (spray)
may sure it flashes code 12, with the diag jumper in place, cranking for 5 seconds.
it must, 51s sure ignore. it will run on 51 fails.
thats it
good luck.
and happy holidays!

pS: keep in mind the EGR is not active at idle., and not at wide open throttle,
it only needs to clos s 100% at idle, (check it by hand, flex its diaphram) if not engine will run like near 400rpm then stall. shaking like mad.
