1989 LANDCRUISER WILL NOT ATART?

insufficient current to run the electronics in the ECM
have an accredited auto electrician check out the charging system, voltage regulator and battery with a load test

sounds like a alternater problem. with car off battery voltage should be at least 12.6 or better. less than 12 volts battery is bad. when running at battery, voltage should be at least 13.5 to 14.2 or better. take negative battery cable off while running, if car dies its the alternater. Good-Day! you can take alt, to any auto parts store to get it tested. advance,auto zone, etc.

stabilitrac is from balljoints prob on tire rods of sway bar and altonator runs at 14v and batt runs 12. for it to be dropping to 12 you need to run to auto zone n they can check your alt. or while its runnind take your batt post off batt n if it keeps running your alt is good and if it dies out rite away alt has to be changed

fram TG5 or a PH5 or a PH13,, depending on what you wanna spend ,, auto zone or any parts store will have them, Just tell them its a 5.7 motor

even thow alt is new it could be bad,,,the fan runs off a temp sender,,if it is bad it will not turn fan on,,,on fan runs off temp sender one run off your a/c or defroster,,if u get a chance to go to auto zone or advance auto they can ck out your charging system for free,,,, hoped it helped,,

test and check battery and or connections to and from alternator also check the connections for the abs sensors may have a loose or damaged connection if looks good than have car scanned for trouble code [even with light out compute still stores code] some auto stores such as auto zone / advanced auto scan for free check ur local area the code will give u a start point towards fixing ur problem good luck

You named the three items I'd look at first. get a manual (chilton or haynes are fine for this) and a digital multimeter. Run the tests on those and likely you will find the problem. You can also remove and clean the IAC valve and passages but do not turn the valve while cleaning or it may not seat correctly.

Make sure its the alt. before you go to the expense of a new one. Take it to auto zone or some place like that and have it chk. out. They will do it for free.

ok the problem consists of your battery..........you have to have a full charge on the battery when you put a new alternator on or you burn out the regulator inside the alternator.....hope this helps!

when alternator warmed up it would not put out proper amps. replaced and works fine.
