88 Camaro TBI Keeps Blowing Hei Module

[Carter Pasch]

Now this should be a pice of cake but it's not. I have put 4 Gm modules in it and a GM Pickup coil a GM coil cap rotor wires ect. It's my GF car so you know what Im up with. The car will run just fine for about a week
with no problems at all ! Then out of the blue and only whe you go to start it just like it blows the HEI module. I have checked all grounds + added a few all diode's eg a/c clutch alt, purg,lock/up solinoids . It has good B+ and good currant to the coil and ecm. good fuse links ect. I was wondering if some how that the starter when disengaded (please excuse my spelling) and the solinoide magnetic feild could spike the Hei ? Sounds like a long shot ,couse you would think the ecm would be poped also...
Any help on this SOB would be very greatfull
Thanks in advance

Can the ecm kill the modual all the way ? Or will it only take out the est part of it and still leave a trigger to limp home ???

i wonder if this is at all a common problem? ask on the chevy camaro forums, they may have seen this before.
