ok so i just finished my first swap, its a b18 bottom end with a b16 head. everything is said and done and it turns over but wont fire. the spark plug wires are in the right order. and i am getting fuel and air?
so what could be the problem?
if you need to ask a question ill reply with an answer?

Archidictus

...have you checked for spark? Is it grounded at all three points (at least)?

NSfit

what are the three points? i have the tranny ground and the head ground whats the third?

pdiggitydogg

ecu grounded?

be sure your spark is strong and white/blue...not yellow/orange

NSfit

whats the ECU ground? just the ECU bolted to the frame?

pdiggitydogg

on the thermostat housing
its 2 wires to a ring terminal

NSfit

yup i have the bolted to the thermostat. and I AM getting spark.
whats the sensor on the back of the TB do? if you loosen it it will turn back and forth about 1/4"

NSfit

does that have anything to do with the fuel mapping?

Luserkid

Thats the TPS..... DONT TOUCH IT! What exactly is the car doing when it turns over?

Can you make a video?

NSfit

ill make a video tomorrow when its light out. as for the TPS i had to put it on the new TB so i did touch it. so i guess i need to reset it.
so when we turn the ignition it cranks over. im pretty sure that gas is burning because when we give it some gas to let air in smoke come out the air filter? what this mean?

Luserkid

Timings off, recheck your timing belt. There should be no smoke coming out of the throttle body EVER!

NSfit

so what do i need to check on the timing belt? its set at TDC? what about the timing through the dizzy?

Luserkid

Timing through the dist wont do anything like this. This is more of a cams are off type deal. Wrong firing order could also cause this but i think from your other thread you fixed that so its probably a timing thing. Set the crank to TDC and see where the cams are. Or better yet if you can put it to TDC and take pics of the cam gears and we could tell you if thats it if you dont know.

NSfit

yeah ill take pics tomorrow when its light out along with a video.
thanks for your help you guys i really appreciate it

NSfit

with the timing belt on TDC is the single mark away from the 3 timing marks on the pulley lined up with the triangle on the block. and the two engraved dots on the cam gears towards each other on the inside right?

NSfit

here took a couple now (i know they're crappy) but to me it looks like the TB is about 1 tooth off maaaayyyyybe 2





is that to far off?

RJonathan

if you're getting FUEL, SPARKS and your timing is okay and your car wont come on, make sure you check Compression? if you dont have compression it wont come on. bestest way is to get a compression test and test your car, if it read zero then adjust your valve lash. and if you have good compression and your valve lash is good. Then Ahh I hope someone with better info can help you.

NSfit

what is valve lash, and how do i adjust it? yeah my compression is supposed to be like 11:1 because my head is milled 0.002"

Luserkid

Without the timing belt cover it looks like your off by a few. Since you dont have a cover stick a long extention down the first cylinder and wait til it reaches its highest point then look at where the cams are. But it does look like its off.

Compression should be anywhere from 150-200psi but your looking to see how close they are to each other when doing this. Your not going to get great numbers due to the motor being cold. Valve adjustment is different for different people and cams, i always use .007 intake and .008 exhaust unless a cam suggest otherwise.

You're not even positive you are getting fuel...

Your evidence that you're getting fuel is: "I saw smoke coming out of the throttle body"

Check more into that, hold an injector up, see if it squirts when you turn it over.

pictures are kinda blurry, if the belt was off by one tooth it would still start, it would just run really rough. did you have the distributor completely off by any chance? "smoking" or some other people call it "farting" ;P out of the intake definately means your timing is 180 out. just for ***** and giggles if your positive your plug wires are in order, take the dizzy out and switch that little piece with the two prongs that go into the cam around the other way, then stick it back in and see what happens.

NSfit

im sure im getting fuel because i took a spark plug out ans it was wet and smelt like gas

NSfit

ok so i re-adjusted the timing and its still not firing. when i open the TB smoke is still coming out my intake "farting"
so what do i do next?

Adjust the valves and make a video.

jdeemseerx

did you adjust the timing meaning the timing belt? or did you try what i said with the distributor?
