240sx starts at cold but not when warmed up

[240sxHeadache]

Okay guys as the title states it starts at cold but not when hot.. but I can push start it when its hot after its warm all it does is crank and if i let it sit for a few minutes and crank it will turnover slightly and die.. I just got my 240sx so bare with me. So I did a auto to manual conversion so the clutch interlock isnt even wired in. Now heres what I've done so far....

-Battery Good
-Alternator Good
-Starter Good ( cold)
-fuses good
-coolant temp replaced and rewired connector
-Ground good
-no check engine

As I mention above when i let it cool down slightly it turns over barely and die. What I'm thinking is the starter solenoid gets heat soaked when hot and would not send enough voltage to turn over.. So i was planning to wire a relay to ignition to solenoid send direct voltage. Can anyone clarify What I'm doing before I do it.. dont wanna destroy my whole car.. Thanks ahead and Please Its my first nissan and first time on this forum.. so easy on the flames.

CTS may be something that causes the problem. For several days I didn't realize my CTS was unplugged and when I would try to start it when warm, it would just crank for a while. However, once I brought it to life it stayed running without dying. That's just my 2 cents.

Fuel pump.

Fuel pump.

I might be new to 240sx But im not mechanically incline.. If the car starts up fine cold and drives with out dying then the fuel is perfectly fine.. My situation is that when its hot it cranks but wont turn over.. But if i were to push start it when its hot it will turn over and go until i turn off then on again. (clearly not a fuel problem)


Miltoon I just replaced the cts because it tossed a code.. I broke the connector because it was brittle and bought a used one from the junk yard.. but I noticed the connector is kinda loose. is that suppose to be normal because the old one was the same. Check engine went away

No, your completely wrong.

A one cause of a bad fuel pump is over heating. Which jut happenes from being driven aka being hot or warmed up. Let it cool down and it starts right up. I know, I've had three 40s do this. New pump = no more problem

Oh and your reasoning to why its not is hilarious

Now you just sound 100% stupid bro.. If its a bad fuel pump how come You can drive it nonstop with out it dying? also If the pump Is overheating when the car is hot and thats the reason it wont start with the key... then What is so different about pushing starting it and key crank starting? Clearly you don't Know. common Signs of a bad fuel pump are dying while moving. you clearly dont know that as well. Also I have a full tank of gas and the ohms of resistance on the pump is within mitchellondemands Spec how the hell is it gonna over heat... People like you are the reason why People waste more money on DIY than going to a shop.. You sir are 100% incline in automotive.. learn the basics please.

Lesson 1 on a crank no start.. Always check Fuel pressure and Sparks (basics)

But clearly This forums doesnt have what I need so ima try Identifix.

This wasn't in my 240sx but in my beater Corsica. I had the same problem, would start cold and run forever but if you shut it off it wouldn't start. I wound up replacing the fuel pump and now it works like a charm.

But since you know so much you don't need help from us zilvians right?

Ahahaha. Your dumb. Simple test. When you know it is not going to start (warm) put gas or starter fluid and see it start. If it doesn't start then hey, me and ^ were wrong in diagnosing your car online. We tell you from experience and you get mad. Believe me I've been there done that. No bull shit I did it all because the car brought fuel pressure and all. So I kid you fucking not after a week of not being able to figure it out we swapped the motor to have the same damn problem. Then swapped fuel pumps and bam. Wasted weeks of time for a hour job.

EDIT: now I read your fucking essay, your a damn idiot and I'm with the guy above me. Shouldn't have wasted my time even trying to help. Your the idiot asking a online forum for help, were the guys who had our cars driving with our head, hands and some tools. Might have did it the hard way at first. But I learned more potential things about bad fuel pumps and only was helping you

You are just dumb as a rock waste more money on DIYs brah... Im already close to my master tech cert I do my diagnosing depending on manufactures spec.

Okay you dont take in to consideration that.. I can push start it.. its true if It wouldnt start even if i push start it.. But I can and it starts..

Also I found out the problem and it wasnt the fucking fuel pump you idiots... If you read my very first post suspecting the solenoid.. it was it..

VWVortex.com - Starter relay for heatsoak problems (http://forums.vwvortex.com/showthread.php?2593146-Starter-relay-for-heatsoak-problems)

Installed that and worked like a charm.

You wannabe techs just got schooled

Cool story, I volunteered my past experience to try and help you. But if you want to berate that's cool too.

I know right.

He is close to his master tech but goes and makes a thread on zilvia cause he can't fix his pos lol. Cool story

Whether it be right or not those who answered did so because you asked, and called them names and disregarded them. I'm glad.you found the problem, but you could have been less of a prick.

Just read the OP, I would guess your starter if every thing else is good and you have no issues push starting it. Take it off have it tested.

Just noticed last post talking about how you found it, and it is the starter. I already typed all this out so I am going to be a post whore about it.....
