rapid flashing ses
« on: August 06 2020, 04:25:00 PM »
so my sis light rapidly flashes with key on,   so I unplugged the ecm power wire   then reinstalled it an it went away.
my question is. this happens randomly   the ecm is a modded one. an the chip is a tt 5.7    I looked at the socket it appears ok. an I didn't see any bent prongs on the chip,


on a side note the car also randomly. dies like the ign is turned off while cruising or coming to a stop


ya think this is related an. what do you recommend I do to fix this?   
thanks

Make sure the bolt that holes the wiring to the ignition module is backed out about 1/8 turn.

If it's ran down tight, it can cause really odd shit to happen.  (like randomly cutting off from time to time)

Normally a chip/ecm problem...or if you have PL, a problem with it making good connection on the end of the ecm.

what codes does it report?

A lot of broken parts does not make you a racer; it makes you a slow learner.

Battery cable to the starter is rubbing on the frame. It's hard to see.

Chip isn't in the socket correctly.
