Hard Starting Rx7
 

ok i have an issue with my 7 in the morning the car will start right away but when its warmed up and i let it cool down for a half an hour it has a hard time starting like i half to give it gas for it to start and im not hitting fuel cut off because i only give it half throttle. lets say i turn it off for about 10 minutes while its warm then go in and start it and it will start right away. i dont know what the problem is. ive been messing with the lean and richness for some trial and error but i am having a hard time with it. please help me out with this issue.

i replaced the TPS and i set it to 1 volt/ohm (wutever u call it) warm so thats not the problem.

let me know what you guys think the problem could be.

The lean/rich pot only adjusts the mixture at idle.

Hot start issues are commonly caused by leaking injectors. Another cause is low compression.

ah ok well thats good to know. i dont think i have low compression but how do you do a compression check? the engine runs very strong

the injectors are not leaking either could the injectors possibly just be bad?

forgot to mention the engine is streetported but i dont know what size port it is the guy i bought it off of just told me that. engine was rebuilt with only about 40k on it now. idk if the streetporting would have anything to do with the starting...

How do you know the injectors are not leaking? Have they been professionally cleaned and tested?

no but good point i will have that done asap then move on from there i will let you know when thats done

found out there was a fuel line that wasn't actually a fuel line i had to replace it with an official line for fuel and now it starts right up every time thanks for your help everyone. i actually have one more question. when i was driving last night my interior lights flicked once or twice im not sure what it could be maybe its just from the cold weather let me know what you guys think. thanks

it has been about 10 degrees here in detroit and my car is taking extremely long to warm up almost like it doesnt want to it only warms up about half of what it should be. do you think my thermostat is worn out? or maybe i need a radiator flush?
