starts out shifting very good after 15 or 20 min. I can not shift if the motor is running I had a mechanic help rebuild the clutch 2 times replaced master, slave & tubing purged as usual also pulled a vacuum on master I am losing no Dot 3 this problem is why I rebuilt the clutch I have replaced the master & slave 3 times in the last 15 yrs. never had this problem before

when I drive my truck for approximately 30 minutes; the radiator, and the big black hose are very hot I can even hear the noise of boiling fluid from inside the radiator. It sounds like that the thermostat is not functioned the cooling fluid
properly through the engine.

what ports do you jump to get diagnostics for 93 Toyota T100

93 T100 looses power at 3000 rpm drives almost normal up to 2500 rpm then I have to feather throttle to maintain speed .

What are the steps to fix this myself. Thanks..

oil pressure is good till engine gets warm,then gauge needle barely moves

Clutch is not working, how do I know what's needs to be fixed?

I had a starting issue with my 93 t100 3.0 v6 last week. Changed the fuel pump and then it started first crank every time. Ran great for a week and then yesterday it died on the freeway and would not start back up. Had it towed home, changed the fuel filter last night(thought it may have been clogged) and it still won't start. Went out first thing this morning to try to start it and it just turned over and wouldn't start. Crawled under the truck, hit the tank with a hammer, then turned the key over and it fired right up, ran good for about 30 seconds then died. Tried that process again and it will not start at all even if I hit the tank. Had someone turn the key over while I was under it and I couldn't hear the fuel pump. So I'm thinking maybe I have a faulty fuel pump or maybe a bad circut opening relay. Any input or advice would really be appreciated.

i can pull the battery cable and it will reset it.

I installed a DVMotorsport gas saver and after one tank of gas My truck stays in low gear , and the low gear is light up on the dash , and the seat belt light stays on unless I shift into low,. And the shifter still moves through all the gears, is it this part and is there a way to test this electronic box ? ? ? ? and I am thinking the gas save module I put on cause all this ,. I feel i should get my money back from them plus the cost of what ever replacement I find, What do you think

will it work

engine light stays on all the time

has 344,000 miles, runs great till this started. Shop doesn't know what to do. Is TPS the same as Throttle Valve (TV)? Any suggestions? Seems electric. Only does it when warmed up well.
Has error code P0755. Replaced solenoid and vehicle speed sensor harness. New fluid and filter too. shifts from 1st to 4th. Won't shift into 2nd or 3rd when warm, about 35 miles then problem starts. Let it cool down for a few hours and it is fine again.

Timing belt was replaced about 40k miles ago. In the past when I have tried to start it, it would crank for a second and then cut off but would crank on the next try. This time when I cut it off and tried to crank it again it ran for a second and then cut off. Now it will only turn over and not crank
