First off I want to thank anyone that can give me any advice. My Wife's car will not start,it will however turn over and try to start but wont completely start. Ive replaced the spark plugs and "wires" i shot ether into the throttle body ive disconnected the line from the filter and gas comes out. it only tries to start when i hold the pedal to the floor if i dont itll just keep turning over.

 

and i have checked the compression and that is fine as well

 

i also used a odbii scanner and it came back clean so im really left scratching my head

 

Sounds like another attack of our infamous ECTS Sensor (Engine Coolant Temperature Sensor).

Locate the two-wire sensor on the driver's side of the engine, very close to where the hose for the top of the radiator is attached. Unhook the electrical connector, and with an ohmmeter, measure the resistance of the sensor. If the reading is higher than 1,500 ohms, or lower than 240 ohms, the sensor needs to be replaced. Get a new sensor from your local GM dealership, not from AutoZone. Also, get a new electrical pigtail for the connector too. Total parts cost about $45usd ....

 

this did not work

 

Start with the basics. You need compression (which you say you have) fuel, (seems to have) air (no restrictions in the intake?) and spark. You say you replaced the plugs and wires, but did you confirm that you actually have spark? Check that first and get back to us. It may just be a blown ignition fuse in the fuse box or could possibly be a busted timing chain. Who knows without further information as to what you've checked. DO NOT keep throwing parts at it as this could get expensive and still not solve the no start condition. A proper diagnostic procedure is what you need to do first. Check for spark at the plugs and fuel in the throttle body.
