ok yesterday i drove to the beach with no problems whatsoever. then after staying there for a couple hours i try to start my car and it wont crank over. i check everything and all seems good and i try again and nothing. Then i try starting it while giving it gas and it finally started. then as im driving along on the freeway at about 60-65 mph im in 5th gear and all of a sudden it starts losing power and even though im giving it gas it starts to slow down as if its not getting any. Only when i floor it does it start to pick up speed. i had to be over 4200 rps for it to drive without flooring it.I think it might be the fuel pump since it is the stock dx fuel pump and i've never changed it since i got the swap. im gonna get a walbro 255 pump today because i've needed one but if anyone has any advice on what else it could be.possibly bad injectors? a bad fuel filter? any help is appreciated. thanks

you need to run a fp check with a good gauge
could be a dizzy starting to go out

 

what should my fp be at? and how do i check if the dizzy is going out? and if it isnt what else could it be

 

it could be wiring done wrong also or a ses
fp should be 35-45 but you must watch it during acelleration i personally have a really long gauge i put it on the hood and watch it from inside while driving
its very hard to test the dizzy its best to use a known good one and try it out

 

k im gonna check the pressure on monday cuz im out of town at the moment. i know the wiring is good because ive had the swap for almost a year with no problems whatsoever except the alternator went out a week after i got the swap. if it is the dizzy where can i buy a brand new obd0 one?? i saw a link on here somewhere but i cant find it anymore

 

very hard to get a dependable one i used distributor kings and i sent it back over 5 times in a year but carrys full warranty except shipping
i have used a ls obdo and cut off a sleeve where the vtec is at and only the top bolt will fit
word for the wise it will increase timing by about 5 degrees so always use the timing light

 

last time that happened to me it was my fuel filter....

 

ok i replaced the fuel pump with a walbro 255 and i replaced the fuel filter as well as a full tune up. car runs stronger than before and hasnt had anymore problems whatsoever. The original pump seemed like it had never been replaced. hopefully i fixed the problem!!

 

Did you replace the pump yourself?? I was thinking about doing it but never did one before.. wondering if it was tricky?

 

i think its your cps(crank shaft position sensor)that is located in your distributor.

pull the carpet up on the passenger side and look and the ecu and wait and see if it blinks.
count the blinks and the search for that code. really easy....

cause if its not letting you go past a sertin rpm, then your cps is was is causing it to stay in safe mode.

just change the dizzy and you'll be ready to go

 

well i dont thinks its the distributor because its not doing it anymore since i changed the fuel pump and filter. but it was letting me rev as high as i wanted as long as i floored the pedal. if i was at half-throttle thats when it was hesitating and not even accelerating. there was no check engine light and i tested the distributor and its getting spark every time. however i did order one just in case and if it does go out ill have one handy to put on.
