SUzuki won't run, what to check

on the side of th the throttle body.
and that is at the end of the throttle cable, bolted to the
engines main intake air plenum.

there were 2 engines used then and 2 EFI systems.
the down draft TB 8 valve.engine G16A
and the side draft. , 16 valve engine G16B

got a symptom?

have you checked the timing is ok , or even that the timing belt hasnt snapped !

the G16 engines all need a cam belt every 60k or will do that like clock work, G16B MPI 4 injector or G16A, TBI ,one injector engine.?????????????????????????????????????????????

compression is not OK, it\'s 150psi or more.

is it? good?, and to run a 4 banger, all 4 need to work. think, 4 engines.

sure the cat broke up, that can clog some mufflers. and cause huge back pressure. (the engine pumps air, if you put a stopper in the exhaust the AIR PUMP DIES)

all engines.

its an old car.

i cant tell you what order to do things.

but my tool box is full of tools , is yours?

the cat back pressure check at the 02 is 2 psi or less at 2500 rpm, but yours dont start, so dropping the exhaust solves that.

i just rack back the exhaust manifold on the bolts/studs.



mr, Otto cycle engine is not new ,nor has it changed.

it still plays by the book , compresson, spark, fuel, in that order.

so compress x4 is what tested sparks out, WIDEOPEN throttle

80psi is common reading x4 (dont be lazy do all 4 )

80 is retarded cam, timing belt never ever serviced, and is now slipped. or heck busted

150+ is good

next is SPARK got spark on all 4?

all are dead, or #1 timing is way retared see slipped belt.

ok spark is good, and timing set.

so it runs on test fuel.

yes, , ok yes, IT WILL.

now we work fueling LAST.

cant burn fuel with no compression or timed correctly

no tools? , all is lost.



no tools , no joy.



(that means basic, meters and gauges, i assume every mech has wrenches, its a given)

To test fuel flow, have a 2nd person stand over air filter (air filter housing open) with a can of starting fluid in one hand. Don't give any throttle, then 2nd person gives 1-second squirt into air filter while you're turning starter motor (no throttle). When engine catches, immediately give one third to one half throttle. Just before it dies, 2nd person should give another short squirt of starting fluid to keep engine from dying. If throttle won't keep engine running and only starting fluid keeps it running, then yes, no fuel is going through fuel lines. Either its a fuel pump issue or maybe there's restriction because of clogged dirty fuel filter. If it starts but runs rough and has black exhaust smoke, then its clogged or dirty fuel injectors.

Check your PCM fuse

could need tuneup and may want to replace fuel filter....Thing i would do first....i hate starter fluid...really ******* rings in motor.....

sounds to me that the ecm is not telling the injectors to fire. is the check engine light on? if so, have the codes read.

does the engine turn over. If it does turn over, is it slow. If it does turn over, it could be the coil not firing, or no gas getting to the throttle body. Spray a little starter fluid in the throttle body and try to start the engine, see if it fires off at all with starter fluid. These are simply done, just hope it's nothing major. Give a little more detail about what it is doing.

If your engine is turning over and you are certain you have ignition fire then I would next check for fuel pressure and if you have fuel pressure then check for engine compression.

Having good fuel pressure is a plus (yours seems a bit high but I don't have specs) What you need to find out is if the injectors are opening and putting the fuel into the engine so it can work. Are the plugs wet with fuel or dry? Does it fire up if you spray carb cleaner into the throttle body while cranking?
