it fires up normally then dies after 2-2.5 seconds. if i hit the throttle it kills it even faster.

im pretty sure its a fuel issue but idk, i have a new walbro fuel pump, new fuel filter, aem fpr, and its tuned on hondata s300.

anybody hvae this issue b4? and how can i fix it?

THX!

no leaks right? hmm and its tuned for the injectors?

 

and cels? Did it do this right after you changes the pump and stuff?

 

did you swap the tps and map sensor connectors?

 

no leaks, except for a small oil leak, but its coming from the valve cover

no cels, only one it has is a throttle position sensor soft code, but its got something to do with the throttle body that causes it, no problems from that in 2 months though.

everything w/ the fuel upgrades was done prior to tuning, so the car worked great with them for a good solid 2 months.

car is tuned, to 285whp for the 550cc's.

running a motorolla map sensor, its worked fine since the tune.

 

bump for the cause!

 

bump again, side not the fuel pressure is right on the money at 40 with the key in the start position

 

What type of map sensor is the s300 set up for? What map sensor are you using?

 

map sensor is a motorolla 2.5, the s300 is set up for it... like i said the car has been tuned and running fine for the past 2 months.

 

lol, I didn't see that you had already posted that. Did you change anything before the problem started?

My brother's CRX did something similar when his main relay was going out.

 

did you check your dizzy rotor?

 

dizzy is new, so are its cap and rotor

main relay cant be going out because the car is holding 40 psi of fuel pressure and the fuel pump is turning on just like its supposed to.

nothing changed from the night before when it was running good... except it dropped down to about 5 degrees... previously it only got down to about 15-20. but temp wouldnt have caused a problem that persists like this.

 

did you check the wiring going to the map sensor and the tps sensor.. if you have them mixed up when u hit the throttle the car will die..

 

sounds like the fuel pump died. do you hear it making a whining sound in the tank?
