Why wont it start?!

[Nik Barber]

No start issue. Possible coolant temp. sending unit. Plug only has .26 volts. No fraid or bad wires to be found. Car i dumping too much fuel. Won't start at all. Does anyone know why that plug has low voltage? Could it be the ECM?

Is it a random no start? Was it running and then one morning didnt start or where you working on the car and it didnt start afterward?

Will Not start. Everything else is good. Spark, compression, fuel, fuses, timing belt. Dumping fuel into combustion chambers. So i checked volts and ohms plug is only showing .26 out of what should be 4.5 to 4.9.

.26 volts means that the coolant temp is 70*F. Hardly a reason for it not to start. Look elsewhere.

Dumping fuel? Do you mean that when attempting to start the spark plugs get doused in fuel?

 

[Nik Barber]

the .26 is straight from the plug when it's not plugged in. The plugs got soaked but i cleaned them and they should be good to go.

I've checked everything else. It just won't turn over. The engine is running super rich. I pulled out the computer and checked for any burns or that kind of thing and it looks fine. The spark plugs were soaked but after cleaning them they should work just fine.

So i just hooked uo my pda to the car through mmcd software. I am getting no trouble codes through the computer. I tried another ecu. same unit and still nothing. accasionally I get a little fart out the exhuast when I having been testing stuff. Nothing really noticible. I read the vfaq on the voltageto the computers temp sensor and they say it should read between 4.5 and 4.9 volts at the plug while the sensor is unplugged. I have spark, god plugs, the injectors are working the compression is good The pda allows me to test the fuel system and other stuff but I am not getting any trouble codes. My friend tells me that when it happened was when he stopped at the gas station and put unleaded in it by accident. he said once he fired it up something was wrong. he drove it to the house while it was running shityg and syphoned the bad as and then put premium in it with a gas can. It hasnt started since then. It seems like it has everything it needs to start but it will not. I believe the problem has to do with the lack off power at the coolant temp sensor plug. I did notice that while I check the power at the plug another sensor or something seems to twitch. i can hear it every time I move the volt meter lead around the power side of the plug. Does another sensor tie into the power otput of that plug or run together. i am losing it. Anyhelp would be great
