im getting fuel and spark but for some reason im not getting gas past the injectors, im really lost i tried cleaning all the ground and the the thermostat ground, tried switching with a known working ecu and main relay, i even switch the engine harness and body harness. yes the motor works this is the third motor i tried and still nothing can someone help me out

 

nobody knows?

 

Have you tried switching injectors?

 

yep i tried tha too

 

I've just come across the same problem with my car and its hurting my head thinking about it.

Nothing is working!

 

have you checked all your fuel lines and cleaned them out and the fuel filter? fuel rail? how much gas is in your tank?

 

did you check to see if your injector clips are getting a signal

 

Im getting fuel to the rail no problem but not coming past injectors. Half tank showing and a fuel filter replaced about 4 months ago.

Im going to try and test injector signal tomorrow.

Is it just a case of putting a multi-meter to the clips or is there a specific way to test as this is not something i've had to do before.

Any help would be great!

 

sounds like it has something to do with your injector clips. you said you tried different injectors and still not all 4 would go bad at once. might have something to do with a fuse.

 

Just checked the clips for voltage. Getting 12v all across and it drops when cranking over.

I checked the fuses and took each one out and checked individually. None gone.

 

how much battery life you have in it?

 

The battery was dead but connected to another car via jump leads and cranked over well.

 

Bump

 

this happened to me before. i ran power across each injector individually to see if i heard a click. two of them did not click. i replaced the two and it started up instantly. if your getting power to the injectors at the harness and checked to see if they click when energized with 12volts across contacts. then i would think it may be ecu related since the ecu is what grounds out the injectors

 

I checked the injectors and they all click when 12v is put through them.

Tried an ECU out of another car too and still nothing.

 

i dont remeber what the ecu use to fire the injectors there has to be some kind of input. it maybe something in the distrubtor if i remeber right. if you have a spare distrubtor you may wana try to swap that out. but im not really sure about that tho

 

Tried a working dizzy too!

Going to go over it all again testing everything again and see if i have missed something.

I appreciate the help

 

yeah im getting gas but im not getting any voltage from the injector clips but the thing is i replace the engine harness multiple times and the body harness

 

did you ground the wires that attach to the thermostat housing.

 

yup i did that and i cleaned it

 

I'm still having the same issue.

Taking the car over to a buddies in the next few days so ill let people know whats going on.

 

Found my problem - broken wire in the harness.

Joined it back up and fired straight away!

 

where at in harness , where injector clips run or further in ?
