I have a 1987 G-20 Van with a 5.7 TBI engine. Recently, it's
began to stall when you make a right hand turn. It seems to do this
more when the engine is warm, but that's not true all the time.
The one thing it DOES do consistantly: Restarting the engine always
requires the key to be turned off before it restarts. Leaving the
key in the on-position, and cranking it, it won't start. Turn the
van off, and then restarting it is no problem, and it starts within
a few seconds.
This leads me to believe that it's a relay problem, or a problem
with the ECM. The engine produces no fault codes before, or during
the event, and everything the computer displays looks OK before the
event, as well as after.
Any help would be greatly appreciated.
(just remove the nospam. from the address... Thanks!)
