Quote: Is that a tbi? I had a 90 tbi equipped ramcharger with a bad sbec (computer) that would die when I hit a nasty bump, took a while to locate that prob. The bummer was, that the computer available at the dealer is only rebuilt and not available new. Still cured the prob. for me.
'92 should be the SMPI Magnum motor.
Definitely, check fuel pressure and for any codes.
