1989 Geo Tracker Questions & Answers
Idles@2500 rpm until engine warms up
old post
all do, everyone. but. the devil really is in the details with EFI.
this IAC valve does that,
to speed it up warm up , put in a 195F thermostat.
this assumes 800 RPM is hot.
most of these engines, do this. new. bewlow.
1: cold start, for 3 to 15sec, 2500 rpm , worse in alaska.
2: then the above DASH pot closes and IAC takes over, at ~1200
3: then as engine heats the IAC closed inch by micro inch a
its now 100% closed and the ECU not controls idle hot.
using the modulated ISC,
there is a fast idle feature on this year, 950 to1000 rpm hot
with these turned on.
1. headlights hot.
2: defrost glass, rear.
3: heater fan on.
4: a/c on if opted.
other wise 800 is normal hot.
My 89 geo tracker blows the 40 amp fuse
You will need to trace the wire to find the short that is blowing the fuse. It can be in the harness somewhere. Usually the harness will be rubbing against the frame parts until it gets to the bare wire. It does take years to get that far
1989 tracker. hard to start when cold but starts fine when warm.
89 has the old stand alone spark distributor.
the ECU is spark free, (no player here)
so here is the list for this engine 1.3 or 1.6L
the 1.3 has a carb. (last one) and is NOT EFI ,
you never said which engine it has. so ill guess at the 1.6L
This engine will have hard starting for the fooling reasons.
we dont guess at it we just do the tests.
- Bad fuel.
- Never tunedup this decade or every 60,000 miles per opr. guide.
- low engine compression 150 good, if all are very low the cam timing belt slipped., (they all do , ignored) and is 60k service point.
- CEL dead key on, bad ECU or lamp bad.
- CEL glowing running, its telling you what is wrong, get the flash codes (DTC's)
- Too high fuel pressure. (bad regulator in front of TB)
- ECT bad. the 2 pin engine coolant temp sensor is bad. test it.
- The injector leaks in the throttle body (look with eyes)
- You find that adding 5-10% throttle cranking makes it more easy that is a bad, IAC valve, the valve at the base of the throttle body is stuck closed and kills all cold start air supply. making cold starts very hard, unless tricked with right foot. yes?
- when any gas engine fails to start cold, i check for too much or too little starting fuel. and for very good spark.
- Good engine, good spark the good fueling, there are tests for each, ASK?
Need to replace accelerator cable for 1989 tracker
Suzuki and GM sell this.I buy mine from Suzuki, many aftermarket parts are low quality (or clones)The 89, was made in 2 places, in 89,CAMI (canada)Japanthe early 89s uses this cable15910-61a10 (suz, pn)15910-61A30 (new design starting at Vin K411nnnnnK= 89 code. this was a mid 89 year change. the vin also shows you what country made.VINJxxxxxxx means Japan actually made.... buying parts is not easy.here is the newer part, a link direct.http://www.oemsuzukiparts.com/parts/index.cfm?make=Suzuki&year=&searchText=15910-61A30&action=oePartSearch&siteid=214330
Idle up and down
First thing to do is check the condition and tightness of the alternator belt. Make sure that it isn't touching the bottom of the pulley grooves - if it does, it is worn out.=========================================
