what could this mean??

 

If your having back fire to you have a to big of exhaust? cause that can cause it to back fire

 

Is the CEL on?

What color is the spark?

I think the backfiring hints that the mechanical timing is off by a tooth or two:

 

spark plug should not be white ^^^^ if white its lean black its rich want like brown cookie color lol

 

yea at the moment i have no exhaust....just headrs and down pipe....but would that cause it not 2 start...?


^^^^thats 1 of the 3 pages i printed and went by...the timing is on i would take a pic and show it 2 u but its dark out side.

idk what color they are all i know is the flams that are spitting outta it are blue.. ish sexy lolz

 

 

whats the cel? Do you have all sensors hooked up(ckp sensor, o2 sensors)

 

The motor is backfiring Blue flames wtf? take pics/vid pls.

 

idk what the cel code is... and i every thing hooked up other then the crank pully 1 cuz its a obd1 ecu...but i did have it in at 1 point...and i dont have the 02's in cuz some 1 stole my headders from under my car the other night then the 02's where still on it...so i just got that replaced...and i was told that the 02's wouldent stop it from starting at lest...

will do looks sick...but cant b good.

 

have you ever had the o2s hooked up? You need atleast one hooked up, from past experience with no starts. So your running a p28 with obd2 to obd1 conversion harness?

 

so it does have a cel code? and do you know how to check for the codes?

 

na i never did rtie b4 i got my head studs...and put everything on some 1 stole them...so never got 2 plug them in... and yea p28 step down.

 

i9 use 2 have the thing that u just plug in and get the code...but 1 of my so called friends stole it out my tool box not 2 long ago.

 

Well you can jump the service connector to see what the CEL's are. But you are right, CKP & O2 wont make the car not start. Is your Main Relay Clicking? Is the fuel pump Priming? It could be that your Grounds are not connected properly. Is the Ground on the Thermostat housing?

 

my money is on your timing being a tooth or so off. i have seen this happen numerous times. It's even happened to me where i looked set the timing dead **** on, rechecked it and it was off.

 

how would i look at my main relay like where?
im getting fuel.
and i will take a look in to my grounds i think there all ther but i will look agan.

thats what every 1 is saying..but iv look over it and changed it like7 times in the last week.... im 100% sure its on the marks

 

yep it happened to me. When my friends helped me put my motor in the first time. They were idiots. They didnt put timing on right and they ****ed up half the sensors. Then they called their friend who actually knew **** who came and put the timing on right. The head was all the way on retarded. So I told them not to come back and now I do all the work with my dad only.

 

my best bet would be to check for the codes, if you don't have a scan tool just jump it by using a wire, there should be a little plug by the lower pass side harness, kinda hard to explain with no picture. See what the codes are first, if they relate to anything that may cause it to not start. Then you can go from there.

 

First rotate the crank pulley a few revolutions counterclockwise to precisely bring both the cam and crank to TDC1. Post clear photos of the cam and crank at this position.

 

ima try and get my friends 2 morrow morning.

will do 2 morrow morning.
