    Firing order on all chevy 350/5.7 liter is 18436572 regardless of year of vehicle

    On the engine drivers side are cylinders 1357, passengers side of engine is 2468 the firing order on the cap is 18436572 and can be position of number1 found with the cap off the distributor and the crankshaft timing mark at 0. This will point the rotor toward the front of the engine to begin engine location of number 1 on the cap. This applies to all engine with a distributor.

I can't figure out how to change my spark plug wires to the right fireing pattern on my Chevy exspress 2500 5.7l 1999 van


go to a parts store and open a book called specs for that type engine or call the dealer and they will give you the order of firing you need free also ask for distributor firing order this will allow you to match the distributor to the spark plug order on engine

My husband did a tune up on my car yesterday and now it wont start it will turn over like it wants to start but it wont he said that its miss firing we have bought 3 new coil packs and still will not start...


If your car is miss firing and your husband changed the coil packs,the wires leading from coil packs to sparkplugs must have got crossed.This will change car timing which will result in the car miss firing.He needs to go over wiring and correct problem for car to run right.You can go online to autozone.com and type in Info about car to get the correct wiring layout.Your problem isnt the new plugs n wires.Its the wiring layout.
