We all know that feeling, especially the broke part. Stop throwing parts at it. You need a good diagnosis. For "cranks, no start" check fuel pressure and spark. For no spark, use a wiring diagram and understand what is involved. The crank and cam sensors are usually part of the mix. The computer (pcm) uses these sensors to determine spark timing, and often injector timing. Also besides coil, plugs, and wires, and the sensors mentioned, don't forget how the ignition system controls the coils- the ignition control module, or ICM. This little part is often the cause of no spark. But, everything can and should be tested first.

It is likely either the crank sensor or the ignition module.

check power distribution center.if ok you have a faulty ignition component.

check 2 see if you have power going 2 your cam and crank sensors. if you do make shure the wires havnt poped out a bit... if you have no power there you will have 2 trace the wiring too see if there is a lose connection...

There are three components that will enrich the fuel mix: 1)engine coolant temperature sensor. If this is not working or the signal is interrupted by a wire breakage then the engine will run rich. The coolant sensor informs the ECU (high resistance) that the engine is cold at start up and so the ECU responds by increasing the fuel injection cycle to enrich the fuel air mix. Later on as the engine warms the resistance of the coolant sensor drops and the injection cycle is reduced by the ECU. If the sensor is faulty or has become disconnected (wire break or corrosion of the socket pins) the ECU assumes that the engine remains 'cold' and the engine runs permanently rich. 2) O2 sensor, operates completely independently of the EGR, if it is faulty and signals 'too much oxygen' then the ECU will significantly enrich the fuel mix to try and balance what it thinks is an excess of air. 3) Fuel pressure regulator. If the diaphragm has broken or there is a leak in the vacuum line this will result in higher than needed fuel pressure in the fuel rail at idle. The vacuum line acts against the spring pressure holding the valve closed. At idle, the inlet vacuum pulls back on the diaphragm reducing the fuel pressure required to open the valve. Low fuel pressure coupled with short duration injection times will mean a lean mix at idle. If the vacuum is compromised or the diaphragm damaged then the increase in rail pressure will make the fuel mix very rich to point of flooding the engine

sounds ike it could be the Crank sensor, do you have the OBDII code off hand?
