i have been laying under this car for 4 days now and have tried 4 new sensors,this car wont start,i barely had the strength to write this and this car is going to kill me.
Did you go to the link i posted and follow the troubleshooting tips / charts?
If you follow the info you should be able to atleast determine the cause of the no start condition. Here is some of the info incase you didn't see / read it.
In an effort to cut to the chase, if the car will not start, one needs to determine three things. Before starting your trouble shooting, be sure the battery is charged and the voltage is not dropping too much when the starter is engaged. If the voltage drops enough, the ecm will not allow the car to start even though the engine is turning over.
1) Is the Check Engine (SES) light on? If it is not, then find out why. The CCCI fuse is one of the problems mentioned in the No Start, No SES Light tree, as well as a bad ECM. I have also found that a blown ECM-SOL fuse will turn the light off and prevent the engine from running although this is not mentioned in the troubleshooting tree for no SES light. I don't see why when looking at the diagrams but it cost me an expensive wrecker ride to figure this one out.
2) Does the ignition have spark? Pull a plug out, put the appropriate wire back on it and lay the plug on the valve cover or hold it to a good ground. Crank the engine. Do you see a good blue spark across the gap? To avoid any fluke of nature, pull each plug wire off and check it for spark on one side of the engine (this will verify that all three coil packs and the module are working).
3) Check the pressure in the fuel rail after turning on the key for two seconds. Is it close to what you have it set at? (this does not guarantee that you have injector pulse-only that you have fuel at sufficient pressure in the rail if the pressure drops into the 20's, the car may not start due to a lack of pressure)
4) Pull the fuel injector harness off an injector (mash in on the spring clip on the bottom of the connector and lift the connector off the injector). Plug your Noid light into the connector. Crank the engine. Does the light blink steadily while cranking? (this verifies that the injectors are receiving injector pulses from the ECM and the crank and cam sensors are working)
Long ago, Jim Testa posted a "How To" get started in the trouble shooting. It is well worth reading in order to apply some logic to the process.
Below is a short cut derived from Jim's article.
No start - no spark, has injector pulse - Check the ignition module (also check the CCCI and ECM-IGN fuses)
No start - has spark, no injector pulse - Cam Sensor or ECM
No start - no spark or injector pulse - Crank sensor or module
This above is a very good way to cut to the chase and start zeroing in on the problem(s).
