Not sure what the mechanic was trying to accomplish there . Start by checking for engine codes . This will eliminate a lot of things or point straight to your problem . Also listen for the fuel pump does it hum when you turn on the ignition on without turning the motor over . You should hear a humming sound for about 3-5 seconds coming from the rear of the car when you turn the key on without cranking the engine . If you dont hear this then your not pumping fuel and your car wont start. If can hear the pump and you didnt get any codes then pull a plug after cranking the engine for a while, maybe 30 seconds of cranking . Is the plug wet or dry. If its wet your getting fuel this is good if its dry your not getting fuel . If not then we should change the filter first to ensure were not dealing with a plugged fuel filter. Try starting it if theres no joy then move on to checking pressure on the fuel rail . There could be an issue with the fuel regulator . Next check the injectors . if you have access to a stethoscope then check the injectors while the cars being cranked over if there working you should hear a clicking sound from them . If there not then look for an electrical problem in the wiring harness , check the fuses and relays related to the injectors.
If the plugs are wet then the issue is in the ignition and you would most likely get a code . either coil , or crank sensor or possibly cam sensor . Any one can stop you and are difficult to figure out which unless its casting a code . Best piece of advice that you can take from here is get the OBDII codes read otherwise your just going to replace a lot of stuff needlessly . Hope this helps

I have an rx8 shinka 6sp manual 05, the dam thing has been perfect until my clutch pedal broke so we replaced the pedal. Then the battery was fukd so new battry . All good exept it's been running weired so it has like shifting memory loss and rpms are lower than they should be but I drove it for 4 months and it got back to normal. Now when I drive it short distances I shut off and it wants to NOT START ONLY AFTER 5 times and waiting like 10- 30 mins it got worse now its sitting and wont start at all . Took back seat out and the line going into fuel pump has gas around it and on top of tank . Wont jump and idk wat the prob is after it did the slow start for months and now it's got gas on top of pump . Is it the pump or the line? My pump kot be here sat and my bf is not familiar with mazdas only AMERICAN cars . He built rally cars and was good at it. But what's my cars problem ? Any thoughts.
I'm having similar problems. The car turns over slow and take a while to start . I can drive it and it does just fine untill I turn the car off and it want start back . If I leave it sitting untill the engine is completely cooled down it will then and only then refire and run . Any suggestions ?

It's a 2005 skinko with 150,000 miles . Car has been sitting under carport for almost a year . The starter speed seems to be close to the same during each attempted start but it does take a long time for it to fire up the first time it starts but as stated will not start again if engine dies or if ignition is turned off untill it completely cools off . 2 to 4 hours or longer .
