ok guys this is the issue now so the car is turning over fine but it was start i don't think its the vats system but i do believe that my injectors are not putting out gas and these are new injectors. I'm starting to think that it could be my ECM but I'm not sure i have good fuel pressure and i have good pump I'm just not sure to what else it could be...
iv read your post over and over and unless I am missing something you got a steering colum out of a different car. For some reason you by passed the the ign switch and made up one. If this is correct this is where you stand. The ecm need to see single from what is called the vats module in order for it to crank and for it to fire the injectors. sense you bypassed the ign switch you concored the cranking problem but you did nothing for the singel that the ecm needs to get from the vats module. The only way for the ecm to get that is, You have to have a matching key resistor to mate with the vats module once you have that it will send a single to the ecm to fire the injectors. So you have 2 choices one is to install resistors in the connection for the vats module at the colum (posted by some one else was the different values that are possible you could go to a electrical suppler and get all the possibilites and try one at a time or buy a used vats module with a matching key and install it. by doing this you would also be able to hook everything up so you do not need the push start. I know you dont want to belive this or hope it is not but if you do not have the veribles that I said it is the problem. I sent you a link to ebay were there a tons of them for sale but you said you got the colum out of a junk car I would go back to this car and pull the vats module out of it because you already have the key for that module. I wish yu luck and wish I could tell you something you wanted to here but I would bet this is your problem
ok so my i went back out there and did homework and found out that its not the vats system because the care is turning over perfectly fine. i even had a lock smith come out and measure the resistor and it match (lucky).... but I'm still not getting any fuel from the injectors. i have spark and i have good fuel pressure....the only think i can think is the ECM is bad or going on. now i need to know if those things are plug and play? or do i have 2 get it programed. also do any on have a good diagram for mr to use to look at for the hose connection

You just have to change the memcal (the thing under the cover on the ECM). Have you verified that you have +12 going to the injectors with the key on? Do you have any codes?
Guessing it's the ECM might be an expensive mistake.
ok.. i read that somewhere about changing the mescal. i don't have any codes....
You haven't answered the question about having +12V on one side of the injectors. If you don't it won't fire. You can check with a meter or a cheap test light.
I tried to be real clear you put a push button swith and changed the wireing going to the starter that is why it is cranking. There is no dout in my mind that if you get the right resister or a new module with a matching key you will get injector pauses. I have tried to explain this to the best of my knowlege maybe someone else can explain it better but they are the things that you need to do.
@ hooked073 i disconnected the push start and i have the right key with the correct resister now and its still giving me the same issues. i also looked on ebay for a module but they didn't have any for my year...now when i stick the key in the car cranks over but will not start. the security light goes off and everything..
This is the new issues I turn the car over but the fuel pump is not getting power but when I run a hard line to the fuel pump it come on. I have good fuel pressure. Second I have replace the ECM with a brand new one and yes I put the chip from the old ECM in. Third my injectors have power but they are not pulsating even with this new ECM in...and the injectors that I've bought are brand new.
The ECM sends a signal to the fuel pump relay for 2 seconds when the ignition is turned on. You should be able to hear the fuel pump run for 2 seconds. If you don't, the relay or its wiring may be faulty, assuming your ECM is powered and working OK (does the check engine light turn on?). The ECM also needs a reference pulse from the distributor to fire the injectors.
