Re: need help asap please
 

Check or replace all of your grounds. Any check engine code? Actually jumper it dont just count on the check engine light to kick. How do you know you have fuel and spark? Not trying to call you stupid or anything I just want to know how you checked them. Leak down test?? How many times did you crank the engine when you did a compression test?

Re: need help asap please
 

i added extra engine an tranny grounds did a fuel pressure test i cranked the engine about 4 times on each cylinder for the compression test the only code i found was the idle air temp but i already corrected that problem i got 1000cc bosch injector someone said it was flooding but i dont think thats the problem it should at least start

Re: need help asap please
 

Do you have a base map for those injectors?

When you do a compression test you should always crank the car an odd number of times for a proper reading I.E. 5,7,9

How does your fuel pump sound? Try a fuel pump flow test. Jumper the main relay:

Then do this. You should have atleast 7.8 ounces in 10 to 15 seconds.

ok i will do the over the compression test my boy has bascially the same setup only with a bigger turbo borg warner s372 with a ls vtec motor i transfered is base map but it still dont work

Re: need help asap please
 

This is dangerous but I try it often and it nets good results. I pull the fuel rail and put a towel over the intake manifold then I have a friend bump the starter to make the injectors spray. You have to hold them in ther or they fly out. That will definently tell you if your injectors are working or not. Again this is dangerous so becarful.

Re: need help asap please
 

well i didnot do but i think they should be working cause when i take out the spark plug there is fuel on them at one point gas was from under the head

come guys i need help im about to sell this car an go buy evo it that fustrating

Re: need help asap please
 

Have you checked to see if your dizzy is 180 degrees out of phase? Without getting technical pull it out and turn it 180 then put it back in. Also check your firing order on the cap. Lastly by now your plugs are fouled most likely so pull them and check/replace if needed. Fouled plugs WILL NOT let your motor start.

Re: need help asap please
 

I have never delt with an LS before but every other honda motor I have delt with the cam and the distributor will not allow eachother to be 180 off it just doesnt fit. Don't try to sell it yet. Its always somthing so simpe its stupid. When you find it you will think man what an idiot it was right in front of me.

Re: need help asap please
 

Who put the cams in? did you adjust the valve lash to specs? .007 for intake and .008 for exhaust on a cold engine for crower turbo cams

make sure yoru timign marks are on for the crank and cams. if the head and block have been decked at all the cam gears should tip forward just a little bit but not a whole tooth.

have you pulled a plug to confirm fuel delivery or your just saying its getting fuel cause the pump is running? did you do the changes in the engine management for the bosch injectors? did you properly enter the dead times for the injectors into the software

what engine management are you running?
