I got a 1995 civic dx with d15b2 bottom end and a y7 after about 15mins of running it just dies I thought the fuel pump was bad so replaced that with a walbro 255 that wasn't the problem I put a reman distributor on bc I thought the coil or icm was bad but not that changed tps brand new alternator and battery all the fuzes are good I can't figure it out can some one help me block was rebuilt like 6 months ago new piston and rings arp head studs cometic headgasket new intake and tb gasket aem fuel pressor regulator new plugs and wires...when it starts acting up if u give it gas it just spits and sputters the. Just dies I can't figure out what it is any ideas

 

Are you using your stock ecu? Any vacuum leaks? Any CELs? Have you checked ignition timing and cam timing? Is it smoking? Overheating? Coolant leaks?

 

Yea stock ecu n

 

No vacuum or colant leaks timing is on it doesn't smoke I can't figure it out

 

Why is it built like this? It sounds like it's boosted.

 

do you happen to have the tps/map connectors backwards?

 

Yea it was boosted I took the turbo Off manifold broke...and the tps an map sensor plug are on the rite spots.it happend when I was driving it so that's y I thought it was the fuel pump... it seems like it's starving it's self for gas when it starts acting up but it's not has great fuel pressur. Do you think maybe a relay is bad when it gets warm it makes it act up

 

What MAP sensor? Stock? Injectors stock?

 

Stock injectors and map...it's basically stock rite now has just a header on it and straight piped to a stock muffler do u think maybe the muffler is plugged... You no how a car runs with a plugged up converter on it that's what mine does when it acts up but it dies I don't have a converter on it tho I'm going to check the cell on it later the car not at my house

 

The only cell that I no it has now is for an o2 sensor

 

Rough idle?

 

my guess is to much fuel.not sure what the problem could be if your saying it went completely back to stock.

 

Idles perfect...

 

main relay possible....

 

I am thinking coolant temp is broken and ECU sees cold even after it warms up causing it to flood,

 

I never even thought of that I'll replace that and see what happens thanks thid92

 

So it wasn't the coolant temp sensor any other ideas

 

I guess I'll try the main relay now

 

sorry to hear, hope you find the problem.

 

I still can't figure out what the f is wrong with the pos I checked the main relay and that is fine the only cel I get is 41 but I've had that ever sence I owned the car it had a iat cel but put a new one in and it still just dies I changed the ecu and wasent that what else would cause this I'm sick of wasting money on parts

 

Does anybody no what would cause this ?

 

You said you put a re-manufactured distributor on it?

OEM Honda??

 

Yea I got it from a buddy I don't no were he got it from tho It's only a month old

 

These cars do not react well to non-OEM dizzys.

 

It sEems likes it's fuel problem when it acts up but it has a brand new walbro pump in it and I had the main relay checked by a buddy u think the stock injectors could be junk...it doesn't have any vacuum leaks but when it's cold and u first start it the gauge is only at like 14 but when it warms up it goes rite to 20 I don't no why never use to do that
