[john walker's workshop]

have the injectors been tested for proper function and a good spray pattern? how do you know there's fuel getting to the cylinders? are the plugs wet? are they black? neither will fire easily. you need hotter plugs with MFI, so they stay cleaner. something like a bosch wr8dp platinum, maybe a 9 even. what color is the spark? orange doesn't get it. general rule of thumb, if you have air, fuel and ignition source, fire will result. you must be missing one of them. does the starter crank quickly or does it drag? put some gas in a squirt can and with the throttles open, give each stack a little squirt. don't do it when you're cranking. some potential for a small stack fire, but if you keep cranking, the vacuum will pull the flame down, or just plug that stack. no air, no fire. with the stock cold start injection system, stack fires were a normal occurance. just keep cranking.
