i need help ASAP. Fresh build wont start. OBD0-OBD1 Kenji Harness, Kenji P28. i have little spark and seems to be gettin fuel but it wont start for the life of it i have no idea...

 

What about compression

 

dont have a tester but how could i be losing compression if it was just built never ran

 

Rings were installed wrong

 

possibly rings installed wrong but i doubt it. is it turning over fine? it just doesnt have that spark to start? check the grounds by the thermostat, tranny. make sure you sand them down and then tighten back up

 

check grounds and codes....wiring is almost always the issure...check to make sure teh cam and crank are both at TDC at the same time....make sure you got the right spark plugs in the right holes....if unsure which is for cylinder # 1 set teh engine to TDC and take the cap off the dizzy and see where it is pointing this will be # 1.....check all connections....

 

all my grounds at the thermo are good the only thing i could think of is my dizzy harness but even still i got it right and it threw a code 9 which is cylinder sensor but i have no idea why **** is so confusing

 

code 9 would not keep your car from starting...mine threw a code 9 for over a year and ran great...I just finally figured out what it was.....what about tranny ground...or the one on the valve cover are they good?

 

main reaaly could have crapped out try a different one of those

is it new or old distrutor, make sure there is a rotor in the dizzy!! personal experience

 

I second the suggestion to check your spark plug wires. I've had the wrong timing with a new motor 3 times ...

 

check all your timing, main reley, dizzy might have gone bad itself, they go bad for **** reasons sometimes. check your wiring, me and my buddies have had our deal of no starts and its been wiring 75% of the time. check by the ecu make sure u did the converswion rite..

 

ok well the conversion harness was bought off of Kenji, all of my engine grounds are on and i even have a ground kit for extra ones my main relay click twice and i hear the fuel pump prime, yes the dizzy is fine i put it on my bros car and worked great.

Wut do ur spakr plug wires have anything to do with timing...lol

 

Well with everything else checked out and as strange as this may sound, check the valve lash and adjust them. I did a build and dissambled the head. When I put it back together I was not aware that the valves were tight so even if my timing was dead on and I was getting spark and fuel, it would not start. Someone told me to check the valve clearence and in doing so I adjusted the whole thing. Sure enough it started on the first try!

 

what engine/dist are you using?

 

i checked all that when assembling the motor, but i doubt that has anything to do with it turning over,,,jsut cranks and cranks

 

i just rebuilt a motor and i cant getting it running right. anyways, did you make sure the thermostat is grouned right. and also tranny. check all grounds

 

yeah i just looked at the topic again. you have checked everything. anyways for the obvious. spark and fuel? pulll the plugs again and take a look. they might be wet?

 

1. Check for spark.

2. Check for fuel.

3. If you have both, check your timing.

4. If timing is correct, and firing order correct, and it is not trying to backfire through the throttle body, then check your compression.


It's really that simple. Step by step. Getting it running or acting like it wants to run is most important.

If it is getting spark and fuel, and the timing is correct it should at least act like it wants to start.

ok i think it is tryin to backfire from the TB whats that supposed to mean???

 

huh? ok first thing did you check spark and fuel? then are you positive you hooked up if the timing belt right? becuase i had so much assembly grease and oil on my cylinder walls my plugs were really oily after running it for about a minute. so they were not getting a very good spark. infact at some times it was only running on 2 cylinders. so i kept having to put new plugs in. now they are dry but still kinda black. once i can get my car running normal then ill just let it idle for a while and burn that all off

 

ok so i checked for spark i get spark but my plugs are being flooded with fuel????

 

You need fuel, spark, and compression in order for an engine to run.

You have fuel, and you have spark, check your timing but if you rebuilt the engine I would worry about the rings not sealing before mixing up the timing.

 

motor wasnt run for more than a minute yet...i mean im wonderin if i dont have enough spark because of how theyu are being flooded...brand new rings and hone job so i should have compression...even if it was bad should be enough to run the motor right

So did the engine start at all ? I would run a compression test to know for sure that is good. And make sure you are getting good spark, if you engine is getting flooded to soon find out why.
