Pontiac Repair: 1993 Grand Am 2.3L SOHC, crank sensor, nut shell

Question
Hi Todd,
I have a 1993 Grand Am, it is a 2.3 SOHC engine.  I changed the engine because the orig. eng. had a heavy rod knock, it was running when I pulled it in the shop.  After I changed the engine and bolted up and hooked up everything I now cannot get it to run.  It appears from all testing, that I am not getting fuel.  I am getting +12v to the injectors, but no pulsing.  I have changed the crank position sensor, and also the ecm, still acts like I am not getting ground to the injectors.  Is there any tests I can do to further isolate this problem and find a solution?  I think I must be overlooking something, I am just not sure what it might be. Do you have any suggestions where I might look next?
TNX,
Glenn

Answer
Hey Glen:

when you did the engine sawp was it an engine from the same year? did you swap the electronics over as well from the old engine or did you use all the stuff that was on the doaner engine? I would make sure you are using the ignition module and coils from your old engine and not the swapped engine. does the engine have spark? If it has spark there is nothing wrong with the crank sensor. the ignition modeul sends the engine speed to the engine computer and the engine computer then sends the signal out to pulse the injetors. in a nut shell that's how that works. Now back track take a look at theengine wire harness especially where the engine and transmission bolt together. ther are 2 studs that have ground wires on them make sure you didn't forget any ground wires to hook up and or when you tightened them up the wires didn't pull out of the terminals. also depending on the model year there is a ground connection on the block by the oil filter that ahs wire to attach as well. But like I said not all model years have that 3'rd ground point. When you turn the engine to the run position and after the bulb check is done does the service engine soon lamp stay on? It should... Good luck :)
