Default 99 ex needing assistance:)

I think my original post may be in the wrong section of this forum... if so i apologize.

ok first off I'm really digging this site. There seems to be a LOT of help and advice givin here and I really like how it seems like everyone is willing to back up each other too! Kinda gives a man goose bumps lol


Ok first off I have been fighting an on going battle with my car like you would not beleive!!

Here's how it started. I was driving my car down the road on day about a month ago and the car suddenly just died..... Luckily I was able to coast it into my driveway where I tried starting it a few times and all it would do was crank. I popped the hood and started looking for any reason as to what is wrong with it. I noticed my dizzy cap was cracked down the back. (At this time I had a MSD cap and external coil) I ordered a new msd cap and waited a week for it to come in. Once it finally came in I was thinkng "ok cool, throw this in and I'md riving again" Yea wrong!!

I also had a VAFC in my car at the time too and following the advice of many Honda "gurus" I took out my vafc and traded it for a stock p28 and a conversion harness. And the msd stuff I traded for a stock ignitor for my dizzy

The car after installing the new parts fired right up... but it reved really high and rev up and down and if you tried to give it gas would almost always die.

I then traded a password jdm front tow hook and my stock p28 to a buddy for his chipped p28 and he burned me a chip with all the knowledge of what's doen to my car. Installed this ecu and the car fired right up! Nice and smooth and everything!!! I'm thinking the nightmare's FINALLY over... But that was till I turned the car off. I turn the key again and once flippin' again the car just cranks and cranks!!!


So this is where I am right now..... The only thing I've found since then is I'm getting a quick one flash spark when I check to see if I'm getting any spark at all.... I took off my dizzy cap and everything appears to be fine on the inside. The only thing that's not there is the blue wire that snaps on the end of the ignitor (Tach wire I'm told)

And as for a check engine light it just stays on...But it just stayed on when the car ran fine too cause after turning it off and before firing it back up I jumped the check engine pins and got nothing out of it.

I have the virgin p28 here with me as well and I tried putting it back into the car and again the car just cranks and cranks....

I even installed the stock ecu thinking it would run but just like shit with the 310's and it wont even fire.

With all that said here's what's doen to my car

J.R. supercharger
310 injectors
fmu
aem fuel regulator
255 walborrow
msd plug wires
stock ignitor and coil
the car was once a auto but converted to 5 speed (if that matters)


I'm begging you guys... please help me with this. I've been on a couple other forums looking for help and advice and I really think they are getting mad at me cause of all the help I'm being asked...

you need to get chipped by someone that knows what theyre doing and can go in and reset the injector size

I have a p28 here that's already been chipped and tuned with complete knowledge of everything done to my car and I'm getting the same result. As for fuel pressure I'm getting 40-42psi

take out the FMU, that is garbage and a weak link, and could also be the cause of you problem since you have a base map on the chipped ecu...

well when I remove the fmu where am I supposed to send all the hoses from it to?? There's a black hose coming from the back of the engine bay to the fmu and then there's th braided line that goes from the fmu to the aem fuel regulator. Do I just somehow connect those 2 hoses? And as for the vaccum line I can just "plug" the end where it's t'd into another vac line so that wont be a biggie.

you should just keep listening to 5speed4life on ohiohondas.. but from reading that thread i think you need to take the car to a shop... youve gone through ALOT of things and imo it has to be something that being overlooked
5speed4life actually works at a shop in ohio.. maybe pm him and see what theyd charge or if he would even want to maybe come look at it on his own time

ok, the braided line is a fuel line, the FMU (fuel management unit) it a dummy unit that was created back in the day before ECU to up the pressure in the fuel line based on vacuum...so all of the hoses and whatnot connected to it, should just go right back where they came from, with the exception of the vacuum line, that can probably just be capped off...the fuel line of coarse needs to be hooked back up the fuel pressure regulator and you need to use the ECU to properly adjust the fuel be increasing/decreasing injection pulses depending on what you need/want...

for more information please conduct a search on FMUs and ECUs

thats just it I dont wanna let it go for a bike because I know how much fun this car is when it was running right at one point........



But I owe the school 758 bucks and need to pay it before my first day.... thing about that is I have the money but if I pay the school then I cant fix my car..... if I fix my car I can't pay the school.. It's a vicious circle I'm in.

can you ask to school to defer the payment so you CAN go to school? i know the university i'm going to be going to has already notified me of deferment abilities, i still need to talk with them more about it, but it is a service that they offer nonetheless...

also you shouldn't need much money to fix your car, like i said you need to remove the FMU first and allow the ecu to take over the fuel management...

if all else can someone tell me where I can find a diagram of the ignition module wires? There's obviously no blue wire and I need to see if I make one where I need to take it to. I was told that because there's no wire then it wont fire up and people are guaranteeing me that's the reason why...

I've been told that there's a blue wire up close to the windshield on the drivers side connected to a little box like thing that's kinda hanging out all by itself. Is that a tach wire? and can I possibly splice into that, send it to the dizzy and crimp a female connector on the ned of it and plug that on to where the tach signal wire should be?
