After replacing almost EVERY damn part in the fuel system, then replacing, the plugs, wires, cap rotor and TPS, the damn thing wont start!

Can anyone lead me as to what would cause this POS to do this?!

 

What engine are we talking about? Does it crank? Do you have spark? How about fuel?

 

22re, fuel is there so is spark and compression

 

What were you doing before it wouldn't start?

 

Cruisin down the road at 35 then she sputtered and died

 

Check for ECU codes.

Then check the 80-amp underhood fuse.

 

Codes are 51 and 71, amd I have thw see through top big fuses amd the 80 is unbroken but kinda purple

 

You need the FSM. You can get it here: http://www.ncttora.com/fsm/

Codes 51 and 71 are switch sensor and egr system. 71- two things can cause that. the engine reaches operating temp and the ECU tries to open the EGR valve but the temp sensor on the EGR valve isn't up to the right temp, or the engine reaches operating temp and the ECU tries to open the EGR valve but the temp sensor on the EGR valve isn't up to the right temp. the first one could be a faulty temp sensor on the EGR valve and the second one could be a restricted EGR passage.
51 is a "switch signal" meaning, IIRC, the TPS is not signalling IDL to the ECU, the clutch switch was on or the a/c was on.

Here are the common codes for Toyota vehicles 1988-95:

Code 11 Momentary interruption in power supply to ECU (electronic control unit or computer) up to 1991
Code 12 Engine revolution signal missing
Code 13 Rpm signal to ecu missing above 1000 rpm
Code 14 Igniter signal to ecu missing
Code 16 A/T control signal missing from ecu
Code 21 Main oxygen sensor signal fault
Code 22 Water temperature sensor circuit fault
Code 23 and 24 Intake air temperature signal fault
Code 25 Air/fuel ratio LEAN
Code 26 Air/fuel ratio RICH
Code 27 Sub-oxygen sensor signal or heater circuit fault
Code 28 No.2 oxygen sensor/heater signal fault
Code 31 and 32 Air flow meter circuit or Vacuum sensor signal fault
Code 34 and 36 Turbo-charging pressure signal fault
Code 35 Altitude compensation sensor signal fault
Code 41 Throttle position circuit fault
Code 42 Vehicle speed sensor circuit
Code 43 No starter signal to the ecu
Code 51 AC signal on; DL contact off (in trany shifter with diagnostic connector jumped)
Code 52, 53 and 55 Knock sensor fault
Code 71 EGR system malfunction
Code 72 Fuel cut solenoid signal fault
Code 78 Fuel pump control signal fault
Code 81, 83, 84 and 85 TCM communication fault

 

thanks for that list TNR it's a little different then the one I was looking at for " OBD I " vehicles.

 

got fuel, spark,compression,air....only leaves timing. have you checked it?

 

The TPS sensor was replaced yesterday aswell....

 

Just because it's a new TPS, doesn't mean it's adjusted properly.

Also, I have learned the hard way just because you replace an electrical part on a vehicle doesn't mean the new one you got was good from the get go.

 

Thats true, how can I test it and how hard is it to adjust to spec

 

Procedures are listed in the fsm.

 

downloading now Thanks

 

Sounds like the timing chain jumped. Have you checked valve timing?

 

no, easy way to check? lol

 

nothing easy about doing things the right way.

 

breakin my balls guys! haha, I have dumped over 400 in parts because of what I have been told/read.. I take it, checking the timing is in the fsm?

 

yup, go find yourself a paper clip too. I try to test everything before I start replacing stuff. But then again, I don't got much to test since I have a carb'd truck and it's gonna stay that way. lol. As long as I got fuel, spark compression and the correct timing, nothing else in the way to tell the engine not to run. LMAO.
