I agree but I am not getting injector pulse at all so weather im pumping gas water or rust I stile should get injector pulse

1styota4X4

and the cold start was working good? did you clean it? The pulse is from the coil/ignitor to fire the injectors. are you getting good spark?

dparker

Yea getting hot spark

weaselman

gas goes bad after 30 days. it varnishes and turns to a honey like substance

i would go through the whole fuel system. specially if it ran great for 5 min...means it was getting fuel, then it stopped. so its partially clogged.

and if the injector is clogged it wont pulse.

I agree but I'm testing injector signal from ECM injector harness unplugged using noid light no signal , I've already checked injector screens an filter, I'm having a no signal from ECM, checked wires 10 an 20 from ECM there good replaced ECM with known good ECM no diff , so I guess it's rime to trace the igf wire to ignitor an the swap ingnitors , any other ideas???? Anybody need to buy a 4runner on 32's lol

How about the ground that goes to the intake? Took me a while to figure that one out. So if your getting a reading at the ecm side, but not at the injector side of the harness, could there be a broken/pinched wire somewhere?

dparker

I am not getting a signal at the ECM so I'm defiantly not going to get on at injectors, if there's a ground on intake off I haven't found it

dparker

No ground problem even added more there is no ECM pulse at or around the ecm

dparker

I found I found it!!!!!! Dint no what the crap it's called but sum kind of sensor connect to coolant an two big vacuum lines pretty much under num 1 injector two wire plug in the two wires were touching killing power to computer some how . Need a new connector what is that sensor called?

eric924run

Chck your ground wires for your ecm. also check ground wire from body to battery and engine. make sure all have good clean and tight connections.

dparker

I said I found it just would like to no what that part is called

Can we get a picture of it??

Yip but b a bit can't upload from my iPhone

Mine sat for longer. The gas was varnish. You have to pull the tank out and flush. Also your pump may have siezed from varnish forming ( mine did). The fuel filter maybe plugged with varnish too.

You may have hurt your cause with bad gas and trash that is now up in the injectors and fuel rails.

The injectors work by switching grounds in the ECU. Make sure everything is grounded properly including the intake manifold. Check the ground under the ignitor to the fender well too. must be zero ohms. Also the ECU case must be grounded too!

dparker

Again I found the problem with this two wires touching killing the computer it starts an runs fine but need to get a new connector for whatever the he'll that sensor is big vacuum line that goes to idle screw an coolant lines it's rite below number one injector

gorillaman2012

ya picture would help..sounds like a pressure regulating valve. the screw is meant to be adjustible

toyotacharles

sounds like cold start injector time switch or ect for ecu, those are ther two sensors just below the tstat near #1 cylinder,

DirtyOregonKid

where are you? perhaps a local user can ID the part for you..

Numbers on the diagram are Toyota PNC. Numbers with "Refer to Fig" in the front are No. for other vehicle categories.
Is this it?

weaselman

its probably the theromstatic switch for the computer..

is it the green or yellow one. is it the right or left?

if its the sensor im thinking of, there are two of them next to each other...

but again, a pic would help...hahah.
