So my friend has a 350, with a Comp 270 cam (224deg at .050) and a TPI with hi flow runners. He's running a custom bought harness, with a 730ECM, and has an autoprom with AUJP loaded. He has 30lb injectors that are new. This engine has zero miles.

Problem is- it wont start... It'll try, a little.

Running $8D mask, TunerProRT

Disabled VATS.

Set injector size to 30. Actually reads 29.xx something

Tried setting the mask to AA to disable checksum, then just let the checksum update at every load to make sure that wasnt the problem.

After a few tries if you pull the plugs theyre pretty wet with fuel.

Not every cylinder generates heat (IR temp gun on header tubes), but every plug is firing when checked.

Plugs are new and gapped at .040. All ignition is new- dist, coil, wires, etc

IAC cycles at key start, as does the fuel pump. Fuel pressure was 45 key on, I believe.


I was looking at the crank fuel setting in the mask as a possibility, not sure if these scale when you change injector sizes or not.

Im looking for opinions and things to check or change, please
