Crank backfires won't start

that was the phone number to Southwest Middle School here in Gastonia when that song came out(but with a 704 area code)!! you talking bout ringing off the hook!! Yep,they changed it.was getting calls from all over the US.

Yeah, that numbers been used in a lot of places.. I'll bet on one thing though, 'IF' that Chevy van has the 4.3 vortec engine .. The distributor cap is cross-firing inside and causing the problem .. Can't look at it and see anything wrong but pull out the DVOM and do ohm test, it will show up then .. Done fixed too many of em! .. Reckon we'll never know though.. Just as well, ....... I'll know!!!
