Ok guys, I'm at the end of my rope. I have a 94 bravada vin "W". It started running rough a couple of days ago. When I would try to acceclerate it would jerk until it got up to a higher RPM or unless I babied the gas peddle. NO SES or trouble codes. It got steadily worse until finally it would stall and not start until it cooled down. Then it would drive fine, but after I turn it off it wouldn't start. I replace the fuel filter, no joy. I replaced the fuel regulator and still no joy. I can hear the fuel pump running and if I pour gas into the intake it starts, but I have to pump the gas to keep it running. It seems like a fuel delivery problem, but I don't know where to go from here because it seems to be related to temp too. I've had the plenum off so many times, I can do it in the dark.

I would start with a full fuel pressure check.
Cold warm and hot and after you drive it 20-30 minutes.
Watch for low pressure or high pressure or a fast leak down.
Post back pressure readings.
