Sorry, this isn't really ecuflash related, but i usually hang out in here and know there is a lot of smart people in here as well.

I have a problem with my number three injector where it dumps an unlimited amount of fuel into the cylinder.

I tracked the problem down to excess voltage at that injector. At key on it has about 12 volts, and under cranking it has about 8. On injector 2 it has about 6 volts at key on and 4 volts under cranking.

It dumps so my fuel that with the spark plug out it will shoot liquid gas out of the hole. When i look down in that cylinder i can see a puddle of fuel on top of the piston.

I have swapped ecu's, as well as injectors (not the problem as it does not happen with that injector unplugged, i also swapped the resistors (both sets that are attached to the firewall by the abs pump), and still have the same problem.

I am going to do some testing with a voltmeter today to check continuity and resistance, etc., between three and other cyilnders.

Any other ideas?

 

I am now posting the resolution.

It turns out that one of the grounds from the exhaust cam angle sensor overheated and burned off its insulation near the valve cover. It burned through that injector wire which ground it out.

I think the cause of this is that i had the external sensor (the one that bolts on hear the plug on the sensor housing) disconnected for a bit and that overloaded the other ground.

Make sure you bolt on the secondary ground!

 

Without a ground it will eventually find one
