Had the spark plugs and plug wires changed on my 1994 GMC Safari minivan, and now it runs very rough. If I stop, the engine shuts off. Backfires a lot also. The whole van shakes bad going down the road....


If your Safari did not expecience these systoms prior to you changing the plugs and ignition wires, then you may have crossed two or more of these wires when they were repalced.

We changed spark plugs & wires on our 1991 GMC & seem to have the order wrong on the distributor cap because truck won't start. need diagram


Here is the firing order diagram for the 5.0 liter (305), 5.7 liter (350) and the 7.4 liter (454) V-8 engines (note position of locking latches/screws between the 3 and 6 and the 1 and 2 terminals on the distributor cap). Let me know if you need the 4.3 liter V-6 engine diagram (hopefully not in a 2500 series truck) or if you require any further assistance.

I need some explanation on the firing order on the spark plugs and how to properly install them. Because my husband changed them out and now the van starts but won't turn over and go!


Hi,

To my knowledge the firing order is 1 6 5 4 3 2.

Perhaps this may be of help for a 2002 GMC Safari Van 2WD 4.3 liter V-6 VIN "W
