Ls vtec has spark and pump primes but only starts with starter fluid
I just built my ls vtec motor its an obd1 motor so I had to change my wire harness I changed it and, mad my dizzy from obd2 2 obd1 and my alternator it turns over has fuel pumping and spark but still wont start now when I spary starting fluid it starts but bogs out as soon as I stop spraying wat could b the problem oh and I only changed the engine harness ive also checked my ecu and main relay eat could it b

Re: Ls vtec has spark and pump primes but only starts with starter fluid
I know you can hear the pump priming but are you sure you actually have fuel pressure??
Reason I ask is I had a problem on my EG where I forgot to clip the filter sock back on properly and it fell off and anytime I would get below a half a tank the pump didnt actually prime and build pressure it would just turn on for the first few seconds when you turn the key...It would also occasionally die out on my after taking a hard left corner until the tank leveled out and it could pull gas back into the system again
Just something simple that may be worth checking

Re: Ls vtec has spark and pump primes but only starts with starter fluid
Ok my spark is orange yellow not white blue this could b cuz of my wireing cuz I did change my wriieng from obd 1 2 obd 2 mayb I got a wire crossed and as for the furl pressure and injectors I c dem.giving me signal cuz they r blinking but not sure of the voltage how do I check that and any wire diagrans to chane obd1 engine harness to obd2 big plug dizzy plug I.also had tajen out the filter in the injectors for the engine could get more fuel but figured day might b a problem so I put them bak but I put them how eva but mad sure they fell into place

Engrish please??
I tried reading your post 4 times and I still cant figure out WTF you were even attempting to say.
FWIW just a LITTLE bit of proper grammar goes a long way

KidEg8: "I just built my ls vtec motor"
Translation: "Good afternoon fellow Honda Civic enthusiasts. I recently completed a transplant of the engine in my automobile. I have a Civic LS which now has a V-Tec engine."
KidEg8: "its an obd1 motor so I had to change my wire harness"
Translation: "The engine I put into the vehicle had On Board Diagnostics version 1. This required me to convert the wiring to OBD2 as my vehicle was of the newer generation."
KidEg8: "I changed it and, mad my dizzy from obd2 2 obd1"
Translation: "I soldiered through the technical diagrams and managed to make the conversion."
KidEg8: "and my alternator"
Translation: "I also had to modify some wiring to make the alternator work correctly."
KidEg8: "it turns over has fuel pumping and spark but still wont start"
Translation: "When I turn the ignition key, the starter engages and spins the engine. The fuel pumps prime and generate adequate fuel pressure and the spark plugs are firing but the engine fails to start."
KidEg8: "now when I spary starting fluid it starts but bogs out as soon as I stop spraying"
Translation: "If I spray starter fluid into the intake manifold, the engine will fire temporarily. Once the starter spray ceases, the engine stalls again."
KidEg8: "wat could b the problem"
Translation: "Heavens to Betsy! I am stumped as to the cause of my engine woes. What could be causing the engine not to run properly?"
KidEg8: "oh and I only changed the engine harness"
Translation: "Perhaps I should mention that I used the engine harness from my original engine on the transplanted engine."
KidEg8: "ive also checked my ecu and main relay"
Translation: "I have checked my ECU and main relay for voltage and they seem to be receiving adequate current."
KidEg8: "eat could it b"
Translation: "Does anyone have any input as to how I can diagnose my problem?"
How'd I do KidEg8? Did I get your point across?

Have you verified that the injectors are opening? You can use a long handle screwdriver as a stethoscope. Touch the tip to the injector and put the handle to your ear and listen for clicking.

Re: Ls vtec has spark and pump primes but only starts with starter fluid
Lol sorry working off a phone ok my spark is orange yellow I got a pik of how the wires r supposed 2 get connected ima try that and the injectors trick that the guy says im going to check my wires make sure its correct as for the injectors I c them giving me signal but ima try that trick

Re: Ls vtec has spark and pump primes but only starts with starter fluid
ok my spark is good now but i noticed that my injector r not letting out gas unless i ground dem out then the spit out gas

Re: Ls vtec has spark and pump primes but only starts with starter fluid
and now when i try to start in wit starting fluid it letts out alot of compression from intake manifold and throttle body

Re: Ls vtec has spark and pump primes but only starts with starter fluid
ok i got some codes with the check engine light whigh was 6 blinks then a puase den 8 blinks then a puase then 1 blink held turned off then another one just like that then 2 blinks

Re: Ls vtec has spark and pump primes but only starts with starter fluid
ok my codes r saying one thing but i have everything right on the dizzy connections my top dead center sensor on the dizzy is connected right atleasat i think from wat i googled i kno its connected good and i kno obd2 dosent take crank sensor so wat else could it b

Re: Ls vtec has spark and pump primes but only starts with starter fluid
and now car wont start with starting fluid since i connected to dizzy cables the way it says i actually get bakfire and its on timming
