Help car wont spool!!

[JesusGLS]

Ok guys... once again here I am. So I kind of decided to go back with stock 450cc injectors since I can get a tune with my 680cc... I went ahead and put my stock ECU and stock 450cc injectors. Now the problem is that I kind of got the car to turn on and idle alright but for some reason its not spooling and kind of has a hard time running. Its not running normal. right now im kind of out of ideas of what it could be. I thought maybe its a intercooler leak maybe a pipe is not connected correctly. What do you guys think. Im running a Precission SC6152e turbo, and well I know it should be bogin after its star spooling because of need of gas but I want to see if it can atleast get it to turn on normal and run somewhat normal, or course i dont expect for it to run as it should because of need of gas but atleast normal.. what do you guys think it is? maybe a intercooler leak or a vacum leak. Im really desperite of help and would appreciated if someone could help me out. Here is a list of mads of what I have...

98 Eclipse GSX
-Precision SC6152e Turbo
-Front Mount Intercooler with short route pipes (everything is brand new not even
-stock 450cc injectors
-Slow Boy ported exhaust manifold
-Turbonetics Raptor wastegate
-3" downpipe with 02 eliminator
-3" full exhaust
-Greddy Type S style bov

Well, it can be several things --

First off, I would pull off your intake pipe and inspect the turbo to make sure you didn't snap the shaft on it. If the turbo is toast, it would do this.

Second, check your wastegate. If it is stuck open the entire time, it will cause this.

Third, intercooler pipe disconnected, or coupler is split.

Either way there are few things that would cause NO boost. It is more than just a boost leak.

I hope you are running an aftermarket fuel pump. As well, 680's will be quickly maxed out on that turbo. 780cc injectors are a little better option to go with.

If your running those injectors i really hope your using an aftermarket fuel pump.
so check your wastegate and check for a boost leak. thats a strange problem your having

hm, i would check your piping first, i remember a while back when i was having the same problem and it turned out to be the piping was disconected.

thanks guys but i think i found the problem.. spark plug 1 & 4 dont have any spark so im sure its the coils. THANKS for your help anyways and yea i do have a fuel pump just need to install it

 

[JesusGLS]

OK.. me again... so I thought I had found the problem with my car but unfortunatly its not the coils... I seem to still have the same problem. I installed another set of coils and still seems to be no spark at all. I kind of went ahead and switched the wires around and stuff since I thought maybe the wires are bad but no same thing... It seem that that there is no current or spark comming out from the first 2 coils if your counting from left to right facing the car. I unfortunatly have ran out of ideas and dont know what it can be..

Your ECU might be shot, otherwise, your cam angle sensor may be having problems.

Check the cam angle sensor by removing the three screws holding on the sensor cover, and check the tightness of the sensor's part that is bolted to the intake camshaft. Also, if there is a ton of oil inside there, it could cause issues as well. A cam angle sensor that is getting intermittent signals will affect your engine by either misfiring, or running on intermittent misfired cylinders. A loose cam sensor (the part bolted to the camshaft) would also cause starting issues, and if it is loose and only sometimes freewheeling, it would cause multiple cylinder misfires.

Put fresh spark plugs in also. What do your old plugs look like? Smell like gas?

Have you already done a compression test?

Yes, it's best to go through Tim's questions first:

It might be a freak accident, but if only one coil is firing (4&1) It could be within the wiring. The wiring for a 2g signal coil goes as follows : ECU > harness to engine bay > power transistor > ignition coil. You will need to see if there is an open circuit somewhere. In my case, I accidently snipped off the engine speed connector (which conjoins the power transistor signal wire to the coil) and had to resolder it to make it work.

 

[JesusGLS]

Found the problem guys it was my power transistor... thanks for all your help!!!

 

[GsXdSmKingGsX]

So its up and running?

 

[JesusGLS]

yes my friend but now i need to get a better tune...

 

[blcknspo0ln]

ah, the PT strikes again.

jaja....maybe u guys can help me in my other thread..
