well i thouight id start a new thread more focoused on whats going on here.
starting facts the car ran a 17.3 best time at 5400feet elevation. was about 70-80 degress outside.

going through the rounds on the engine heres what been done.
dizzy that locked up has been fixed and timing is currently stock 15btdc
got the vacume lines hooked up corectly thanks to racer_smokin1 for borrowing his car as a reference.
new cap and rotor is on, got wires and a hi-pro coil on order.
about to get the fuel filter replaced here in a few minuts....
got a tru c.a.i. on there now.
this weekend i had a chance to check out the timing belt looks in decent shape, also verified the cams are in time with eachother perfectly.
my biggest concern all along about the fuel being off or the pump going bad and that i was geting 40+ mpg was brought into light today.
got a gauge on the fuel rail a few hours ago........the adjustable fpr on the aem rail was set an 29lbs...... i set it to 40 for now i think i remember reading that that was about where its suposta be........

Q is the fuel rail suposta loose all presure and 0 out when the engine is shut off? because it is a few people have said yes i am just seeking more opinions.....

its funny the car still dosent feel right its to jerky throught the powerband.
feels like fuel cuts and then the pressure comes back.
further more if im cruzing at a set speed with my foot on the gas not moving trying to hold an even rpm like say 3rd gear at 3krpm's and trying to keep the car there it will sparatically feel like it lost a little power and slow down a tiny bit then the power will come right back.

and its still taking more than 5 revoloutions but not more then 20 per say to start the engine.

there are no check engine codes no fuel leaks and i stil think the fuel pump is bad....

I was just gonna post about eCtune again, then I saw it was you and we had talked about it... good luck... every once in a while mine will take a bit to start, but just a couple times after the swap, I wait for the fuel pump, but I think maybe I just jumped the gun a time or two... hope you get some help.

but every single time the car sits for more than just a few seconds...

only way to make it start faster than 5 revoloutions is by priming.

again ectune or ecu tuning alltogther is the only way to go i just need this thing solid for 1 or 2 more track run before the money comes for the real tuning. and theres stil a few more mods to work out.

is it losing fuel pressure like an SOB somewhere?... maybe you were on to something with that line of thinking? you can still rep me for the ignition timing if you want ;)

that was a straight up gain...
not it runs smoother or "seems" better.....
before i poped the filter off i checked one last time the fuel pressure gauge was 40 dead on the money and when i reved her up about half 2 wot it would raise to 43 tops

replaced the filter and asked my girl to read me the gauge as i primed it she said the highest it went was almost 50
started the car and the pressure was at about 46 lbs and half reved just over 50
had to turn the pressure down
poured out some fuel from the filter....it was black
took her for a spin im gona get greedy here and bump the fuel up in 1 psi increments and see how it feels...

also shes been sitting for about 5 minuts now ..the startup test

good to hear, I would be tempted to tinker with some stuff like that if I hadn't been fully tuned...

ya dont mess up a good thing.
i just want to land a 15 before i get invasive in modding this engine.
if it cant do it it might not be worth it....

so i advanced the timing again in accordance with my elevation.
i cant get the timing nailed tho theres to much a fluxation in the reading and i know it is because of the worn out wires. so its pretty close ill say to where it needs to be but not perfect.

took that for a drive....couldent really tell, felt like it smoothed out.

took the fuel presure up 1 lb and realized im not going to feel a lb so i doubled it and went for a spin. the powerband feels like it wants to go higher no flatness like before. i wonder if it needs more i can play around with it but ill never really know until i get a wideband on it. lets be modest tho with just headers custom 2.25 exhaust and a cai the fuel shouldent need more than just a kiss of adjustment.

the best sign all night, ive been consistantly starting from a dead start to wot and shift at 6500 consistantly then back to wot and up through 3rd except this time the tires chirp when i droped second.


and the car starts right up!

somethings not right.
the chilstons states that the 95 <-"as high as my manual goes" h22 takes 24-31 psi.

at the same time my engine is not the 95 model.

according to the guy i bought it from its a 96 not the 97 i somehow got in my head. does anyone have the spec for fuel pressure for the 96 h22?

does anyone also happen to have the specs for the 97 and the 99?

did you say if it was loosing pressure or not when you turned the car off... cuz i dont think it is supposed to

my ride<----check it out
MY 240 project~~ 300hp here i come

are you measuring pressure with or without vacuum?

yes yes finaly this is the help ive been craving
lets get one thing straight

i am testing and tuning it with the vac line on....i have not removed it from the start.

and yes the pressure on the fuel rail drops to zero absoloute 0 within a second or two of the car being off. its a aem rail and adjuster with a areomotive gauge hooked right to the rail to the small 8mm hole just to the left of the f.p.r.

still looking for those presure specs guys i need the pressure suggestion for the 96 97 and 99 h22!!!!!!!!!!!

today with the almost 200 miles i had to drive some highway some city i spent the first half of the day runing on 42lbs the motor feels very smooth and pulls good.
i then droped it down to what the spec is for the 95 h22 (24-31) started at 24 the vtech engagement feels stronger it realy does but only that area amnd only at 5500-maybe 5600.
then i brought it up to 28 felt about the same maybe a lil more low end power then i brought it to 31 and it feels like a smoother overall but stil dosent feel right 42lbs feels the best!

again im going back to the problem lyes in the pump and not nessisarly presure at this point but volume am i compensating for this with pressure?

to many questions but please continue to contribute ideas!

i really need those specs tho guys once again the fuel pressure specs for the 96 97 and 99 h22a1

with the vac line disconected from the fpr the pressure jumps about 10 lbs on idle and of course dosent move any higher when you crack the throttle.
with the vac line on the presure drops about 10lbs on idle but jumps about 10 lbs when you crack the throttle.

i had to read that 2 times my self after writing it lol

without touching the adjustment...
conected:
30lbs idle
40lbs reved

disconected:
40lbs idle
40lbs reved

did i miss something about tuning it relating to the vac line?
looking back at it now all the years in my manual (up to 95) state a fluxuating fuel pressure. same as most other cars.
it seems it jumping about 10 lbs is why they refer to the fuel presure in a range not a set value. 24-31lbs for the h22 up to 95 (as far as my book goes)

~45 psi with the vacuum hose disconnected is the factory spec.

for what year?
your 100% on this?

every year.

yes.

hang around for a while longer and you won't doubt this guy ^

if hes driving a h23 vtech then i wont be due to doubt anything.
ill follow his advice mindlessley.

thanks guys

haha, good plan, and again, good luck...

form your own opinion. Please dont take everything i say as the bible. I don't know everything but i do have a lot of experience with preludes and the H series.

well shes runing alot better v-tech feels smoother after a good motor flush and puting her on a healthy diet of synthetic amsoil
theres a few loose end i gota tie up with the ignition system and get the stock muffler off after i had to go to cort oer the modified exhaust canon but the whole exhaust system i had replaced all on custom 2.25 with a cat size 1 step up. cant wait to get her back to the track!
