Car running lean and Wont idle

[92tsifwd]

My car starts up every time and then amediatly stalls even if you try to give it gas. Also my boost gauge reads zero psi at full throttle and my spark plugs are white so I think I am running lean but, don't know why because my car is mostly stock. It acts like it aint getting enouph fuel. I changed my timing belt, water pump, and fuel pump to a stock one. I checked the timing. My car ran fine for a while and then just started acting up. M capacitors were replaced in the ecu also. My boost gauge reads 0 psi at full throtle. There is vacume at the boost gauge line. I plan on checkin fuel filter and vacume lines and I dont know what else. Any help would be apriciated.

Don't hate me but, I need to know what the problem is.
bump.

Do you have a CEL? After you start it, remove the plug and see if they smell like fuel. If so, its likely a ignition problem

No CEL was on. I changed the fuel filter and spark plugs and now I am getting lots of fuel on the plugs but it will not start. I am running out of ideas. I have a extra coil pack I am going to try and put on tomarrow. Any other advise?

I just tried my spare coil pack and cleaned the gas covered spark plugs and it wont start. Could it be the CAS or the knock sencor or somthing? I am ready to give up.

Just curious, but how do you test full throttle pulls if the engine wont run? You aren't going to be able to boost much if any if your engine has no load on it, especially if its not running right.

It sounds like a bad or unplugged MAS could be the problem. Unplug it and see if it does anything different.

When it still ran it showed 0 psi @ wot in all gears and all vacume lines check fine along with fuel. Now it won't even start.

I unpluged the mass and it had no effect. Is there any way to check the CAS to see if it is bad? What would it do if it was bad? Does anybody know how to do a spark test? Also how do you check the thing leading to the coil (transister pack) mabey? I have a spare mass I will try later and if that don't work I will unbolt the down pipe to see if the cat is clogged. Other than that I don't know.

Does anybody know how to test the cam angle sencor or transister pack leading to coil or how to do a ignition spark test?
