Reply To: GM 3400 crank no start except with ether after head gasket job

[Adam Singer]

Things I’m suspecting:

-Poor ground/weak spark of some sort?
-I didn’t check the actual voltage to the fuel pump at the pump but all connections were looking good. No corrosion at all. I’m not sure what spec the fuel pump pressure should be.
-I did not check cam sensor signal

What else?
