1G my 1g gst will not display codes.

I tryed jumping the connector and I get nothing from the cel. Can someone give me a hand.

Sounds like the ecu is bad if your not getting any codes, you get a cel.

I just got it working. Will report back

code 21 25 and 13 note the mass air was unhooked

Hook all of these sensors back up to the codes assigned. If you still get these codes, either the sensors assigned to these codes are bad, or the ECU's drivers that runs these sensors are blown, which curtails a rebuilt ECU to solve these issues.

13-Air Temp Sensor .. located in the MAF
21-Coolant Sensor (this is a common sensor that loves to fail causing major operational issues)
25-Barometric Sensor.. located in the MAF

-Good luck-DSM

if I ground one of the wires and the gauge jumps to full hot that means its the coolent gauge. Am I correct?

Coolant sending unit connection wire.
