Question From kellerjt7 on 94 isuzu trooper

replaced battery last week, died yesterday. had it on a charger this morning, and it started right up but our battery and engine lights are still on

Response From Hammer Time Top Rated Answer

The battery light doesn't mean the battery is bad. It means the charging system is not recharging the battery. Likely a bad alternator but it needs to be tested.

Oil Sending Unit

Question From derf22 on Oil Sending Unit

Year of Vehicle: 1992
Make of Vehicle: Isuzu
Model of Vehicle: Rodeo
Engine Size: V6 3.1ltr
Mileage: 188,248

I have a 1992 Isuzu Rodeo with a V6 3.1ltr engine with a bad oil sending unit, I also have a 1990 Pontiac Firebird also with a V6 3.1ltr. Can I use the oil sending unit from the Firebird in the Rodeo? Recently I put the Firebird alternator on the Rodeo and it works great, so would all the engine parts be interchangeable?

Response From Tom Greenleaf Top Rated Answer

I'm VERY surprised the alternator fit, wires and all! Just found two different part #s for the two cars for oil pressure sending units for use with GAUGE,

2002 Isuzu Rodeo will not turnover only headlights and dashlights work

Question From amandatapp_159 on 2002 Isuzu Rodeo will not turnover only headlights and dashlights work

I have an 2002 Isuzu rodeo 6 cylinder. Friday it kept loosing power to everything except motor no radio, power windows, no gauges worked, no a/c, and automatic transmission at first would work as long as you changed it manually then got to where it would not get out of 2nd and only go about 20mph. It had to be jumped when shut off, parked it for the night and next morn went and put a diff battery in it and it drove normal to auto zone they tested my old battery said it was good then checked battery and alternator in it and said the alternator was going out and it was already draining battery in it before I got back home everything quit working but motor. I went to take out old alternator and found wires that were corroded so I fixed them and reconnected them when my wife went to crank it, it arced bad out of old alternator then no longer would even try to turn over. Took old alternator to auto zone and when they tested it a red light came on there machine and then machine shut off so it was def bad. I went and put the new one in with no problem, but still nothing but headlights and dash lights work. There is no clock which is always on even with no keys, no radio, no a/c, no tail lights, no door or dome lights, and will not even turn over at all, battery is fully charged, alternator is new and tested good, and I tested all fuses on dash and in fuse box under hood and nothing was blown, but still only have headlights, and dash lights, and can hear what I think is fuel pump cutting on. Does anyone have any idea what might could be the problem and how I might can fix it, its the only car my family has and I do not have the money to take it to a mechanic

Response From Discretesignals Top Rated Answer

What do you have for testing electrical circuits?

Response From amandatapp_159

Just a test light

Response From Discretesignals

Did you check the 100 amp main fuse? If the alternator shorted the battery wire out, that would probably be the first fuse to go. Use your test light and make sure that the test light lights up on both sides of the fuse with the test lamp connected to battery negative.

It is in the fuse block under the hood.

Looks like this and should be bolted to the bus bar:




1995 Rodeo Isuzu won't start

Showing 4 out of 9 Posts | Show 5 Hidden Posts
Question From wrdavis on 1995 Rodeo Isuzu won't start

1995 Rodeo Isuzu 2.6 4 cylinder, Manual Transmission, 2 Wheel Drive, 180,000 miles
Had two problems.
1. Battery was not charging, so I replaced the alternator with a remanufactured one from autozone. This fixed the problem and I confirmed that it was working by starting the motor and measuring the voltage at the battery at 14.5 volts. At this point I was working on a second problem, which is the engine would bogg down when you accelerate. So I was re-adjusting the TPS, replaced the MASS AIR FLOW sensor (and cable, because the connector on the old one had become so bad that it needed to be replaced), and at the same time I was charging the battery, that was low due to the alternator being bad. Once I was done with these tasks I tried to start the engine, but it wouldn’t start. I started to investigate and found that I wasn’t getting spark to the spark plugs. I decided to replace the ignition coil, but still no spark. Upon further investigation I found that I also didn’t have normal voltage readings at the M AP, MAF. I checked all of my fuses and relays and fusible links and they all appear to be good. The only other information that I have is the blower, AC, and charge fuse circuits appear to be dead, both with the ignition on and off (not sure if engine needs to be running). I tried to trace through the schematics, but still no luck. Could this be the ECM or is there something else that I am missing?

I just had a look at my power distribution diagrams and I’m going to suggest having another look in the fuse/relay box. Test the fuses with an ohmmeter; late production had a 100 amp early production model a 60 amp fuse that protects the circuit(s) that you mentioned, along with portions of ECM & ignition system?
These are large amperage fuses and would take a dead short to ground from a high amperage circuit. Maybe something like an alternators main terminal; could it have touched ground while replacing the alternator?

I checked the 60Amp Fusible link for continuity and it was good. I just noticed that the check engine light is not coming on when I turn the ignition on. I believe that indicates I am either not getting power to the ECM or a bad ECM. I can't remember if the check engine light use to come on, but it definately is not coming on now. A new light that is coming on when I turn the ignition on is the RrABS light.

Response From DanD

The check engine should be coming on; the ABS light should come on when the ignition is first turned on; for a bulb check and a state of health of the system check, then go out.
With the lights doing what they are; I’m still thinking a power feed problem; it’s not likely those two different computers crapped out at the same time. You said you had wiring diagrams; check what pins of the ECM & ECBM connectors are power feeds and then make sure they have power at them? Either constant or ignition feeds.

The RrABS light does go off after a few seconds, so that is a none issue. I checked the power to the ECM (Red/Wht) and it is showing 12 volts, so it is getting power. I have a feeling what happened is when I cut the wire on the MASS AIR FLOW it might have shorted out the ECM. According to the schematics the MAF has 3 wires and a braided wire connected to the AIR FLOW SENSOR SHIELD. I reconnected all of the wires and the braided wire. The thing that I don't understand is the braided wire ends near the connected end and doesn't appear to connect to the MAF. I do see this same braided wire connecting into the ECM.

Response From DanD

This braided wire is a shield to prevent interference produced by other electrical devices from entering the MAF return signal wire.
It is only connected to ground through the ECM.
Have you checked for ignition feeds, connector C210, terminals 1 Lt green/red &14 Lt green/black should have power via the ECM relay with the ignition on?
The ECM relay is found in the fuse/relay box and is protected by a 15-amp fuse in the same fuse/relay box.

Response From wrdavis

Still concerned about the braided wire and shield. I don't want to blow another ECM. Could this cause the ECM to act this way? On this vehicle the MAF wires are enclosed in a grey taped bundle. When I cut the wires to splice on the new connector and wire, I noticed a copper type shield where I cut. Is it imperative that the shield be in a certain location and be perfectly intact, or is it just used for reducing electical signal noise? Again I have reconnected the ground, hot and signal wires and the braided wire. I had to replace the connector and wire because the old one was falling apart and needed to be replaced. My current plan is to get a used ECM today and try it.

I previously checked the ECM relay and it is working and the ECM fuse is good. I haven't tested the power at the terminals that you mention yet.

Response From DanD

It's just a shield and as long as it's not touching an exposed insulated wire it'll be fine.

I replaced the ECM and now everything is working great again. I would like to thank everyone for their responses.

Question From 97trooperhelp on Power steering problems?

1997 Isuzu Trooper, 3.2l V6, 158000. So the alternator is fine for my Trooper. My next question is where is the power steering unit located on the Trooper, and what are all the parts that are belt driven. thanks again

Response From Hammer Time Top Rated Answer

Just follow the belt and you'll see all the belt driven parts.
