2000 gmc savanna, Van starts up fine but when I get to a stop it will stall sometimes and the other times it will act like it wants to stall when I give it gas, runs great when it gets going


The first thing you need to do here is have the computer control system scanned for fault codes and an have a engine running test done to see what is going on in the automatic idle speed control system.

My gmc 4.3 stalls when warm and wont start without ether. then it runs fine


I had the exact problem with my 1993 chevy c1500. I found that the IAC was sticking so the engine would die at idle after warming up and the ignition module was pulsing the ECM intermittently after the engine warmed up so the fuel pump wasn't being turned on after the engine died....I replaced the ignition module and the IAC valve and all is good. I don't know if testing the ignition module reveals that it isn't sending pulses to the ECM.

Truck would not start, gave it a blast of ether, it started


get your self a fuel pressure tester, hook it up to the fuel rail, you should get at least 30 psi with key on, 30 to 45 psi with engine running.
