I have a 2004 Mazda rx8 automatic with 57,000 miles and having a problem with it
it has a new battery, spark plugs from dealer, new ignition coils and swapped out new coolant and oil and oil filter

My problem is that is will not start back up when it shut downs until maybe 5 to 10 minutes and also my coolant light is always on but I swapped out the coolant and also has a small difficultly of starting it.

Please help me and thank you

 

Is white smoke coming from the exhaust? If so, the head gasket is going..thus why your coolant light may be coming on.

 

Are u still using the N3H1 Starter? (Stock Mazda 1-ish KW 11 Teeth)

Might wanna look into N3Z1 or better still N3R3 starters (2-ish KW 13-14 Teeth).

Good luck

 

Could have jumped timing.

 

How can an engine that does not have a head blow its non-existent head gasket? Maybe learn the basics about the car before dispensing advice?

Well, our dual timing chain / timing belt setup IS difficult to keep in sync!

 

OP, what you are experiencing is known as the "hot start issue". There are a lot of threads on this forum that cover the potential causes.
