If i try to crank the engine it starts, but the fuelpump doesnīt run, so it getīs lean and dies.

I tryed to scan for codes, but when the fans start, the computer disconnects.
No SES light.

When I jump the fuelpump by the testconnector, the engine starts and runs, both fans still running.

What can cause this kind of problem, bad PCM, VATS?
actually that could be a bad ECM, bad flash, or a serious wiring fault preventing the ecm from booting up properly. when the fans run full time and you can't connect to the ALDL, that's bad news.

just for fun start pulling fuses and relays (everything except PCM BAT and PCM IGN) and see if you can keep the scanner connected?
