[tkd rx7]

o.k i have a 85 rx7 12a hears my prob i turn on mr car it warms up and when i drive it anywere and turn it off it wont turn back on until the next day but now it wont turn on it sounds like it whants to but nothing . i changed spark plug ,starter,msd coils,i also check the fuil line is good filter is clean. im just lost and need some serious help ?

a motor needs 3 things to run
compression
spark
and fule
first run acompression testand if that checks out then
make shure the plugs are firing you can touch the plug to any groung and turn the car over and you should be able to see spark. or you could put a inductive timing light on it and see if it flashes when you crank.
if that checks out
then you go to fule
is the pump getting power?
is the ecu sending pulses to the injectors. it is 12 volts. and you can use a test light
. your problem lies somewhere in the above

well I had a 86 RX-7 One year ago I had the same problem when I took it to the dealship they told me that the car was flooding out and that it was a big problem for this car he had put a swich in to turn the fuel pump off what the idea was when the car flooded out you are able to dry the spark plugs out by turning the car over a few times then you turn the fuel pump back on and the car starts right up Trust me this DOES work !!!!!
I used this trick untell I rolled it over !!!!!!!!!

yea I told him in an e-mail that it was probably having a flooding problem, and after hearing your story, I'm pretty sure thats it

[STINKINLINCOLN]

Ok, so did he get it fixed yet are do you know

[Soyo]

not a clue

i just realized that was the same problem with my 87 rx7 because the ex-owner told me about the switch and i didnt pay attention unill the next day it didnt turn on and i shut off the pump and cranked it and when it felt like it was gonna turn on i just turned on the pump. is there any way to fix this problem????

[STINKINLINCOLN]

not that I know of this way works for you right
why mess with a good thing

[tkd rx7]

thanks guys for all that info but the weird thing is when i put oil into the carb it starts up evry time but then it shut off and it wont start could it be my compression and if it is that how much comp should it have more then 150?.

[MBTN]

Sounds like a hot start problem. How many miles on the motor? It could very well be a compression problem.
