Hello out there. I'm rebulding my 1971 K5 Blazer and thought a 454 would
look good under the hood, so I bought one. Tore it down, did the mandatory
things to rebuild it, put in a Summit HEI distributor along with a Painless
wiring harness and a Holley Street Avenger 770CFM and Hooker Headers.
Well, it ran last year- 2003- and towards the end of the year- Oct- it
started to develop a backfire above 25 mph and under acceleration, so I
parked it until yesterday.
Charged the batt, turned the key, engine cranked, sputtered once, and just
kept cranking. So I check to make sure fuel is there, it is. Check for 12v
at BATT on coil- ok, ohmed out coil per book, ok, ohmed out green and white
wires to pickup- ok, had Advance auto check the module- ok. Still no spark.
Rechecked timing- the old fashioned way (thumb in #1 hole, crank motor)
rotor correct under cap, timing mark at TDC, still no start.
Any thoughts on what my next troubleshooting steps should be? Am I missing
something blatantly obvious?
Thanks in advance.
