Temperature needle stays on the hot and doesnt move even when the car is cold?


YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.

1992 isuzu pickup,2.6 engine , surges up and down after 10 minutes then shuts off


1992, PICKUP, in USA? what country , ? cars are not same all over earth. sorry.
engine surges, then stalls. correct.>?

nice testing , rare here, real nice !!!!
spark good as it stalls
so if engine is ok, compression, (seems cat is not melted with 20 " HG)
is flooding or starving for fuel,.
one or the other, you can find that out.
if spark timing was ok, then the belt did not slip. on cam)
leaving only fuel issues.
so DO the magic , WOT, cranking trick this trick (logic in ECU)
cuts the injectors dead, cranked, to unflood all engine with EFI.
do that?
check spark tips, for 3 to 4 hours dead.? be next
2.6L (is 4 cylinder.) is cam belt drive, i never fail to check it first
the fail, at 60k miles, all do. all rubber band engines do.,

if all this is ok, not flooding
one can start engine with test fuel, and even keep it running
even with (hint) fuel pump relay pulled.
if that works, the fueling is wrong.
injectors leaking,? ?
if only one spark tip is wet , soaking in fuel, Injector issues.

when it stalled pull all 4 plugs and look at the tips.
(if cam is timed right) be super super first thing, on this 4 banger.

I had the car in storage for 35 days. Upon startup, battery was dead. I took the dead battery out(only 1 year old) and put in a good battery which started the car, while the car was running good I took out...


You recycle the old dead battery

Have no idea why you even put that back in

Common sense & your friend is correct

You don't disconnect anything on today's
vehicles, even with the key on

Put in a new battery,start the car, warm it up
& drive it for awhile & maybe you will get lucky
& it will complete some of the drive cycles & run some
monitors ,you know nothing about & it will be fine

If not, your mechanic friend should be about to stop
by with the bosses scan tool & help you out

Check your ignition switch (located on the steering column under the dash) If this is working, you will hear an electronic switch click when you turn the key on - if you do hear it then replace your starter

Guages went dead, tranny not shifting from 3rd gear


Your transmission appears to be in "Limp Home" mode. This usually indicates an internal transmission problem that the computer has decided is too serious to allow regular operation. EVERYTHING, even your windshield wipers, has to get permission from your computer to operate. When the computer interferes with your operation of the vehicle, it sometimes gets overzealous and does other, more funky and entertaining things than it actually needs to do to protect or disable the vehicle.
The next place you need to go to in this vehicle is a transmission repair facility, attached to a tow-truck. They will confirm/eliminate the transmission as the problem. There are other things it could be, but it's telling you "transmission" and you need to have that confirmed/eliminated first, because it is almost always the most destructive and expensive fault a vehicle can develop. Don't drive it again, because it's cheaper to repair a transmission that has not grenaded.

Stalling problem


Possible throttle position sensor(TPS).Does the idle even out if you bring the RPMs up to say 1000?All engines spend most of their time at idle,that area wears out in a TPS first.By barely increasing the engine speed you can get past that dead spot and drive your car normally.Of course that doesn't fix your situation but it helps you understand why it happens and how to continue to drive your car until you can replace it.Duralast / Throttle Position Sensor Part Number:
TPS140 is only $33 at your local auto parts store.Good Luck!

I suggest you pull the battery and have it checked. Most chain auto parts stores will do this for free. It can take a while if your battery is dead. Another way is to swap batteries with another car. After you get your car started disconnect the positve ( red) battery cable. If the engine dies your Alterator is bad. If you have a bad Alterator it could have ruined your Battery too. If the engine continues to run it is probably a bad battery.

Replaced ignition switch, nothing happens now


You will have to take the switch apart again, and give the little shaft a half turn, or else it's not in all the way.
