Here is the story I had a coolant line bust and my 4runner overheated. Once I replaced the line and added coolant it would not start. I have replaced the COR, spark plugs, and ignition coil. I then put a noid light on my number 1 injector and I am not getting a pulse. Any ideas I am loosing my mind, I hope it is not the ECU.

 

Also I tryed shooting starter fliud through the intake. Nothing happened.

 

So, you are not getting fuel?

are you getting spark

do you have compression?

If the ecu was bad, the CEL would not come on when you turned the key to run (it should for a few seconds).

 

I have fuel, compression, and I am getting spark. I do not think that I am still getting a good spark though. After replacing ignition coil and spark plugs I would think I would be getting a blue spark when I ground it to the block. It is not blue and it doesnt look real strong. Is possible that it could be the pick up coil? I read somewhere that the pick up coil sent a signal for the injectors.

 

put 3 or 4 tablespoons of marvels mystery oil in the cylinders and let it sit for 8 hours and try again, even though you have compression your rings may not be working correctly

 

Ill give that a try. Still shouldnt I get something from spraying starter fluid. Notta, nothin, wont even try.

 

checked the 15amp EFI fuse in the box under the hood?

you never know

 

Thanks. I have checked the fuse. I have checked all the fuses and done all the resistance checks associated with the system. At this point I am really at a loss. Keep all the advice coming. What would keep the injectors from getting power and the spark plugs from getting a blue spark?

 

Cleaned all the grounds that I could find. Seems to have a just a little bit but still I am getting the same out come.
