Read post 6 in my signature. MAP and other critical sensors share the same ground. MAP is the biggest player in regards to flooding.

Fuel pressure checks out too

Sure the CPS isn't just weak and it's not flooding?

We have three different cps sensors and none of them change a thing

Do the stuff suggested then. Known issues.

Fired up now. Idles but backfires and stalls when hit throttle

Sounds like a fuel delivery issue. Ever have a fuel pressure gauge on it while it's acting up?

Bypass the resistor real quick.

Ballast resistor bypass didnt change

Fuel pump may be dying.

Is it whiny sounding?

Sounds normal. Would that cause it to flood?

Read post 5 in my link. You'll see that 3 things in the same circuit, all affecting mixture to a different extent, share the same ****ty ground circuit.

I'm awake now....

Bought another cps and it worked. Thats 4 of them. It still has trouble starting but it runs awesome once you getit started

Do the test and mod.

All of the other stuff I suggested, when combined, has a benefit. free and easy.

Yes we will go over it all asap. We just needed to get it running for a trail today. Ill give you an update once we thoroughly go over it.
