Why she no run?!!? =[

[2JZmx83GTE]

lol SOLVED

Power at the injectors
Sparks
and motor is getting fuel

Engine Codes 14, 24, 31



1991 Cressida mx83
jzs161 2jz-gte

errrrr just tried to change the title to something helpful but I can't =[

[wa5]

are you sure the engine is getting fuel?

[wilbo666]

I'd try running it with the AFM unplugged as opposed to a GE AFM to be honest!

Pull the codes is the first thing to check (Tc to E1, then a light bulb between +B and the W pin in the diag box...)

Also you haven't given a whollllleeeee lot of details in your post here (i.e. 2JZGTE VVTi from what engine, in MX83, stock everything? etc, etc) :S

Cheers

Jigga the fuel pump so its always on and see if it runs?
Sounds like the ECU is not powering the pump when its seeing a RPM signal - AFM fault etc

[cresslux]

make sure the fuel lines are the right way around, and check earthing. the ecu uses a ground from the engine to fire the injectors, if its loose or has a bad connection it wont start,or show any error codes. just had the same problem with a mates 1jz ra23 conversion!

If i undo the connector and hit my fuel pump switch it pisses gasoline everywhere

JZS161 in MX83 all stock

Fuel pump rigged on a switch.

Yes.
It feels like the ECU is telling the injectors to start but not to flow while running, not sure if that is even possible but... ya.

Sound like something with the COR or main engine relay?

^hopefully these are representative

14 - Ignition Signal Circuit
24 - Intake Air Temp Sensor Circuit
31 - Air Flow (or MAP) Meter Circuit

This is with the MAS/afm unplugged

[dumbass]

how the fk is the going to run right with no power to +B and +b1
also pretty sure they r semi fly by wire so check for power at the ECTS or what ever it is at te ecu
get a noid light and a spark tester so u can atleast test the very basics of any internal combustion engine

also test for 5v at the tps as this will tell u if ecu is turned on

sounds like your over your head but final test is get some aerostart and spray it down throttlebody and see if it starts

[dnegative]

I have no power at +B, +B1, nor BATT. ( should've mentioned this at the beginning )

That's like trying to start a car with no battery lol

[dumbass]

hehehe
I have seen a 20v run without the small 3rd plug which powers the ecu
so that's y I didn't say it wont start without that plug

anyway he needs two wires that need battry
and then mrel hooked up
and igsw hooked up
and +b +b1 hooked up

[2JZmx83GTE]

Well, I had COR trigger grounded as stated on another forum but if I give it power then I get power at +B +B1 and BATT...
