Question about 1994 Toyota Pickup

5 Answers

I have an intermitant problem with my 89 pickup with 22re. It starts fine, runs fine about 2 miles to my destination. About and hour or two later it won't start; engine turns over; check engine light is on and there is no spark at the plugs. Sometimes after 5 min or so it will start; sometimes not. In hot weather it didn't start for a day until morning when the weather was cool. A few times it stalled at a light after about 2 miles; check engine light; turning over; no go, but started in a few min. I put in a new used coil and a new EFI main relay. Apparently something somewhere is turning off the spark. What could it be.

    I have an intermittent problem with my 89 Toyota pickup with 22re. It starts fine, runs fine about 2 miles to my destination. About and hour or two later it won't start; engine turns over with full power; the battery is strong and the check engine light is on. I checked for spark at the plugs and there is no spark. Sometimes after 5 min or so it will start; sometimes not. In hot weather it didn't start for a day until morning when the weather was cool. A few times it stalled at a light after about 2 miles; with the check engine light on; turning over fine; no go, but started in a few min. I put in a new used coil and a new EFI main relay but the problem is exactly the same. Apparently something somewhere is turning off the spark. What could it be? While the problem is intermittent, it is not random; it happens pretty much the same way every time. Because it has been happening more frequently over the last few weeks, it seems like whatever is causing the problem is getting worse. Are there any sensors, relays or other things anywhere in the system that would stop the spark, while allowing the starter and all other electronics to work?

    I have an intermittent problem with my 89 Toyota pickup with 22re. It starts fine, runs fine about 2 miles to my destination. About and hour or two later it won't start; engine turns over with full power; the battery is strong and the check engine light is on. I checked for spark at the plugs and there is no spark between the spark plug wire and the plug. (When the car is not working there is no spark between the wire and the plug; when the car is working there is spark)I also tested for spark between the coil and the distributor and found none, although I didn't try this when the car was actually running to make sure my test was done correctly. Sometimes after 5 min or so it will start; sometimes not. In hot weather it didn't start for a day until morning when the weather was cool. A few times it stalled at a light after about 2 miles; with the check engine light on; turning over fine; no go, but started in a few min.

Because it has been happening more frequently over the last few weeks, it seems like whatever is causing the problem is getting worse. Are there any sensors, relays or other things anywhere in the system that would stop the spark, while allowing the starter and all other electronics to work? So to recap: whatever the problem is causes the "check engine" light to come on AND prevents spark from reaching the plugs, but does not effect the cranking of the engine or other electronics.

    Are you sure that this engine has an ignition module? I can't find anything about one in the Chilton's manual, nor do I see one on the car. Maybe it's the secondary coil, you're talking about? Chilton did say that there shouldn't be continuity between the neg terminal on the coil and the igniter body. Do you know anything about this. The Chilton manual is very bad and I'm not sure I trust it.

    The check engine light always comes on when it stalls or won't start and is never on when it is running.

    It has stalled 3 or 4 times; each time after driving about 2 miles. Each of those times it restarted either immediately or after several minutes. More often, after driving 2 miles and letting it sit for several hours, it won't start at all until after the engine is completely cool; usually the next morning. It always starts in the morning, but one day I waited until the the afternoon of a very hot day to try and it wouldn't start until the cool of the next morning.

    I've been checking the ignition components according to the 1993 manual and the Chilton's manual for the 1989-1993. Chilton has different specifications for many parts of the 89 22re as opposed to the 22r and the other years. Chilton specifies that there should be no continuity between the neg terminal on the main coil and the body of the igniter on the 22r, but doen't mention the 22re. I have continuity. I had continuity when the car wasn't starting and also when the car was starting. So I don't know if that's a problem or not.

    This seems to be a heat related issue.

    With Chilton in hand, I am unable to locate an ignition relay, the ECU (whatever that is) or any capacitors. Maybe these things are called something different? I need a better manual but there are none localy.

This is actually a rare problem with these engines. This sounds like an ignition module. This will probably be located either in the bottom of the distributor or on the outside of it on the bottom. Shouldn't be expensive. about 40 bucks or so. Give this a try, it can't hurt. Hope this helps. Good luck.

Did the engine light go on before it acts up weird?  
This did happen to me a couple of times with a Toyota 4AGE engine.  We found the cause of this is the wiring.  We re-did all the wiring of the engine to the ECU.
On another car, this also happened but it is due to a grounding cable of an engine which was loose. 
The mentioned above issue also has stalling as one of the symptoms.  Please confirm if you experienced any.
If you never had issues with the car stalling then you may want to check the loop of your ignition.  Check the capacitor if they are ok and the ignition relay.  You may also want to check on the brushings of you starter.

Spark plugs are the one who burns the gas. If there's no spark on the plugs, the engine will die because there's no good contact. The burnt CARBON is the reason. You have to take the spark plugs out and clean it. On the spark plugs, you will see the carbon that's wrap around it. Use a pointed tip and sand paper to remove the carbon. Then, put everything thing back and it should run smoothly.

Please try it first.

Good luck and have a great day!

Hi

Hi!
Check the battery. If you do not have sufficient voltage and cranking power, the car simply won't start. Have someone attach booster cables to your battery if the engine seems to be turning over slower than normal. If the battery seems charged, and the starter motor still doesn't turn the engine, the problem may be in your starter motor itself, or the battery cables. Changing the starter is not too complicated, but if you decide to attempt this, try to find someone who has done it before to help you, or buy a do it yourself manual that has a description and pictures of what you need to do. You can also test to see if the voltage is going thru to the starter motor, if not some times you can cross jump the solenoid and start the car.
Remove a spark plug wire from your spark plug and use an insulation handled screwdriver to ground the metal fitting inside the spark plug boot to the engine, and have someone turn the engine over while you watch for a spark. You should have the metal screwdriver shaft about an eighth of an inch from a clean metal surface on the engine, and be careful not to touch any un-insulated parts of the tool while testing the plug. If you do not have a spark, you have an ignition circuit problem, and depending on the vintage of your vehicle, you may have to replace anything from a coil wire to an ignition CPU, or computer.
Please do accept this solution and revert for further assistance.

Thanks
Rylee

First step, see what is missing when it wont start, fuel, or spark. Is it carburated? or fuel injected. (22re should be injected.)

89 toyota pickup electrical problems


Sounds like you have an intermittent electrical problem. Check your positive battery wire going into your fuse box the connection becomes loose. I have seen 2 or 3 Toyota pickups have the a similar problem. Also check Battery connections and the ground cable.

If your pickup has a loose battery cables and/or wires it can not charge to it full potential no matter how new your alternator or your battery. Try turning on your head lights and wiggling your battery wires if the lights go dim or flicker, chances are that wire is loose or has a bad connection.
