Ive had a problem with my rx7,i cleaned my K&N air filter and put it back on, i turn the key and the moter just spins no spark the tach dosent move at all like it usually does and no smoke coming out of the mufflers so i know its not flooded, it seems that the ingnition isn't working i did a post a week ago and tried all suggestions none worked, as i was taking things apart and putting them back together i got in the car and tried to start it, the car started and then stalled i was happy for a sec i got out the car and saw that the MAF was disconnected i must of forgot to put it back on, anyway i put it back on and nothing now the tach doesent move like it does with the MAF disconnected it off i can't explain it? does anyone know whats going on does the MAF effect ignition at all????????

You didn't say what year, but the S4 models will kill the fuel pump if the AFM does not see air flow or is disconnected.
