1989 Toyota Pickup SR5 - Answered Questions & Fixed issues

My friend is a part time mechanic he gets his solutions from www.reliable-store.com he gets from their every single detailed info, instructions, diagrams, error codes, troubleshooting, transmission etc. everything on all vehicles, and factory manuals for service, repairs, parts, owner's, operations, maintenance etc. U can get help from there there is a girl at chat she can help you

Best Manuals That's an old model. Save money from mechanics, try these online books if you can. Very useful, really I have attached link of the website I've used frequently

Proportioning valve divides pressure among lines. See pic below and follow link for more details on your truck. An easy test you can do on the hoses is to remove the front two hoses that go from the frame to the calipers and blow thru them. These hoses can decompose and block flow like a reed valve. Blow from the frame end of the hoses and see if the left one is restricted. http://www.autozone.com/repairinfo/repairguide/repairGuideContent.jsp?pageId=0900c15280061362

The diagram shows a capacitor between the regulator red wire and ground on some models. If your truck has that cap, you may want to check it or replace it. I don't see anything else on the diagram that could cause this behavior, unless there is a bad connection somewhere. If that red wire powers the field winding, a bad cap could be pulling down the voltage.

The suspension components need to be checked for excessive wear on the front also the steering track rod ends for play Jack up on axle stands and try to wobble the wheel for play

You can push in on the switch with the door open to get a feel for how it works. Push it in and your dome light turns off. The same thing happens with your brake light switch. When you push on your brake peddle it is the same as your truck door being opened. When the brake peddle, is in its home position as in no pressure on the peddle pad, the arm of the brake peddle pushes the button in which, breaks the circuit to the brake lights.

The switch could be bad. It is easy to spot the switch look at the arm of the brake peddle and see if you can see a bracket that holds the switch against the brake peddle arm. Use a flashlight.

You might be able to tell if the switch is bad by only removing one of the wires and see if your brake light goes out. If your brake lights go out with one wire removed, the switch most likely is bad.

I have also seen where a driver caught there shoe string or shoe on or under side of the peddle and when they pull there foot up they bend the bracket that holds the brake light switch. By bending the bracket they move the switch away from the peddle arm and the switch no longer gets pushed in enough to break the circuit.

A bent bracket can be an easy fix just bend the bracket back to its original position. Please be very careful the bracket can be sharp. In addition, the bracket can crack, to help prevent this let your truck heat up inside if the A/C has been on etc.

You can take all of the wires off the switch and remove it. Take the switch to your local auto parts store they should have one and will be glad to test your existing one.

If there are more then two wires draw your self a diagram, tag the wires with masking tape, and number them. Please be aware that you could blow a fuse if you touch the wire ends to any metal parts of your truck.

If you do not already have fuses in your glove box, you should pick up some while you are at the auto parts store. Please put the fuses in your glove box. I run into many people who say yes I have fuses, at home in there garage! I do not know about everyone else but my truck never breaks down in my garage. I think it is scared of all the tools around it. LOL.

I hope this helps.

Take care and stay safe

Thank you

-What do you need to put back together...? A car, motorcycle, boat...? Good Luck Mai

Start with the basics.... 1-Scan and/or Preform manual code retrieval 2-Test for spark 3-Test for fuel pump running /Fuel PSI 4-Test fuel injector pulse If you need further help, reach me via phone at https://www.6ya.com/expert/ralph_2f0886b7d6af32ce

i think your better of changing the whole engine to a turbo powered one as not possable to convert normal aspirated engines to turbo aspirated unless your a magician , sorry mate can't be done

Your fuel pump could be week or fuel filter needs change.

They don't work off the same unit. First check the fuse, then the turn signal unit . If that is ok the problem may be the signal switch.

when it is lit it means you should shut your engine down and check your oil level before driving any further unless you have lots of money to pay for engine repairs.

I believe that the TSP on your Toyota is adjustable. Follow the manufacturer recommendations to adjust the position of your TPS, and MAKE SURE YOU PUT THE RIGHT TPS ON THE VEHICLE.

check the width of the chassis rails for starters . If the same width then check the cab mount distances . With 9 years between chassis I would think that the chassis will be different

Ryan, Do not put a used cam in your engine.. 1983 cam is 30 years old and probably has a lot of wear on it. The R22 engine was one of the best engines.. if you must change the Cam.. look to the after market or a cam grinder for a replacement cam. Orielly Auto parts sells 2 Performance Cams for your truck.. Check this out.. Don't cheap out. install new cam bearings and lifters if you expect an improvement in performance. http://www.oreillyauto.com/site/c/detail/MEL1/27101/02244.oap?year=1989&make=Toyota&model=Pickup&vi=1277715&ck=Search_02244_1277715_3038&pt=02244&ppt=C0364

I had check the spark at sparkplug because the crank and cam sensor send a signal to the computer who trigger the coil driver and injector driver. check voltage at injector wire and ground. One wire on each injectorshould have 12volt ignition on. The computer trigger the ground. For the spark use a SST225 it is cheep

set the timing at 10 Degrees advanced

bring it to the auto parts store they will check it for free

no photo , no joy. which screw, a mounting screw, some have mounts and calibr. screws. the mount ? remove the other screw, go to any hardware store or auto store and match it, hint its metric. as them for help. diameter and pitch and lenght must match. or any toy dealer. show screw, he matches it.

why not post a full question. above are all nouns, devoid of even the hint of a question.
