ok heres the deal i got the motor running good i took it to the shop to get the prob fixed and he said he fixed the prob he said all i need was a new fuel pump and it would run good. so i went and bought a new walbro 190lph pump and put it in and its still doing the same thing but worse. heres what its doing i can crank it up and it runs fine but i can give it gas and it will bog like its geting to much fuel and its not burning it ,but i can just eas into the gas and it will rev up i cant even drive the car it bogs so much i need to find out whats wrong with this car so help me out guys

 

recheck all the vac lines going to the map sensor and make sure its also hooked up. mine did the exact same thing its seems back asswards and it was just i forgot to hook the map sensor on the tb up.

 

my car did that when the timing was fucked

 

well i took it to the shop and the guy checked everything he set the timing and fix all the vac lines..........heres what gets me before i changed the fuel pump i changed the fuel fliter and it ran good for one day and then it started it agin so i changed the pump and its doing the same thing could the filter be stoped up, its just pissing me off someone told me it could be a bad ecu or im sucking air from some were

 

well what do yall think it is

 

Is this some redneck shop or someone that knows what they are doing? I only ask because I am also from MS.

My ZC did the exact same thing when I dropped it in with the timing off.

 

Is the check engine light on? Is the ecu flashing any codes?

 

no the guys name is lamar and he knows his **** and know theres no codes

 

my b18a1 did that when i first dropped it into my crx. the timing was off a tooth.

the way to tell?:
get a timing light. autozone has them.
hook it up and put the light on your crank pulley. if the lines don't match up or are very very close with the distributor set directly in the middle, then your timing IS DEFINATELY OFF and needs to be fixed.

 

he told me he set the time .................. after i got the car back from him i changed the fuel filter and it ran good for a few hours and then it started running like **** agin could it have sucked up trash and stoped it up i think im gonna change it agin and see what it does

 

well its not the fuel filter i changed it and it didin help so im lost now ...............i can press the throttle all the way to the floor and it will run but just pop and cut out like a sum bitch i can just eas out on the throttle till little less than half and it will rev and not miss or anything what cold this be could it be something to do with my firing or could it be my ecu im gonna try a zc ecu in the moring and a new cap and rotor and see if that helps yall think real hard the timing is set at idel it purs like a kittin and cranks with eas what could it be

 

hey i juss did this swap into my crx, and it runs successful no problems. I've been a honda mechanic for 2 years now, and ive seen this sorta thing...i can't really pin point your problem, but i can give you sum idea's...the main relay, controls the fuel pump, so if it is intermitant, it could be that. unplug the connector that plugs into the pump, and check the ground, and make sure it isn't faulty our nething. I don't know those are juss sum ideas, thats wur id start, but yea....since you already took it to a mechanic im sure he already checked that stuff...juss a thought.....
good luck man...

 

thats the thing i just changed the fuel pump to and i made sure everthing was right could the fpr be messed up not holdin the fuel back

 

I would check the tps sensor. Did you wire the tps correctly (reversing the outside wires)?

 

Perhaps you have some sort of injector problem. Use some known working ones and see if that solves the problem.

 

my crx wit b18a did that too and i took to shop cuase i was stumped he said fuel pump he replaced it ran for about a month then same prob, had a friend thats smart with wiren lok and it was the ground on the main relay we regrounded it it ran fine for bout a month than happed again and it was my dizzy so got a new dizzy and it works fine, sounds like ur timing but sharing my .02

 

i also have a question about b18a1, i have one in my 91 hf and i wanna swap it into a 91 si, do i have to get new wiring or can i use the same wiring? is your distributer good?

 

all the wiring will work with a si

 

would the distributor have anything to do with that at all?

 

DId you check your injectors? When you floor it if they are bad it will cause them to drip instead of spray like they should. Giving you the effect your getting.

 

what size are the stock inj in a b18a1

 

240s i think

 

ok i have another ? i took the car to this guy i know he works on all kinda cars and he said my prob was the valves ............ it cant be that i have them real lose right now or could that cause the valves not open all the way

 

im looking for a guide to swap my b18a1 into my crx si where can i find one

 

hook a timing light up to that bad boy STAT
