Help me. I'm goin CRAZY!!!!!!!!!!!!!!!! I got a 2nd gen 86 13b. I tried replacing the coils. The car ran good this winter. Now that it is warming up, after driving the car for a while. Starting and stopping, etc. The car won't start. If I let it cool for a few hrs, it fires right up. I tried buying new coils, not new igniters, and it worked fine for the winter. Now summer is here and after it warms up and you shut it off... nuthin! Let it cool for a few hrs and it fires right up. Any ideas would be helpful!


Thanks,

Jim

 

leaky injectors/low compression

 

check for bad grounds

 

you could also try changing your plugs

 

I have replaced the plugs and have fresh wires. The injectors check good. Someone once told me about cleaning the engine by spraying some kind of cleaner in the air intake while motoring the engine with the fuel pump fuse pulled. You let it sit for about 30 mins and start the engine. This is supposed to clean out the carbon buildups.

Has anyone heard of this? Also is there a good way check the igniters before replacing them? I have a manual but don't see anything regarding this.

Thanks,

Jim

 

mine did the same thing ... then one day it would onlt run for 15 minutes and shut off ..... then I parked it and left it for a week .. after that it would only run for 5 seconds.. now nothing ... I did a compression test today with a piston tester .. it was a cheap one and I couldnt remove the check valve , but I figured that it would still give at least a shot in the dark.... it came out at 52 psi .................. I am currently drunk ..... I bought it in october and have only driven it a month .... when i bought it it showed 110 psi .... still havent even finished paying it off ...... .. supposedly it only had 60 000 km on a rebuild ... 9 grand , flush

 

could be a water seal :!:

Make a fuel cut switch as shown in these threads: https://www.rx7club.com/forum/search...archid=1949110
