Before we just grab straws and try throwing parts at it , how about some history as to what work has been done so far. Since some brands of new parts have been found to be troublesome , could you tell us what work/ parts have been done/replaced ? BTW , have any dtc's ( diagnostic trouble codes ) been found ? I realize the engine won't stay running long enough to set a code but have any been logged at all ? A crank sensor is what tells the pcm what position the engine is in to start the ignition and injection timing to start the engine . The cam sensor follows in advance when the engine is accelerated much like a distributor vacuum and centrifical advance but in electronic parameters to communicate information to the PCM. The fact that the engine starts and runs ( even for just a moment) suggests the ignition is working due to feedback from the crank sensor and cam sensor but these sensors should be checked to be sure. We cannot assume they're not part of the problem. I still feel the fuel system ought to be checked for pressure readings . A fuel pump,was installed but is pressure adequate . Lots can happen in the fuel,system . A bad check valve in the pump , hose connection leak from pump,to sending unit causing pressure drop , leak in line to fuel rail , etc. . Just some thought , please tell us what you know based on my questions hoping to,give some insight . Hope this helps . Greg
