91 ignition problem - The 1947 - Present Chevrolet & GMC Truck Message Board Network

i know i am new here but i hope you guys could help me out. my 91 suburban was starting to miss a little bit so i decided it was time for a tune up. so i put new wires, plugs, rotor and cap on. now i have no spark at all. i then put a new control module on and then a new coil. i still have no spark. what should i do next. the engine is a 350. any suggestions would greatly be appreciated.

are you sure it is missing spark? have you checked to make sure it is getting gas in the TBI? it might be something as simple as a loose 12V wire or ground going to the distributor or the coil..

also our burbs were known to have a "wear spot" on the distributor assembly just above the gear... it is best to replace the whole assembly if this is the case...
