i30 no spark after engine swap!!

[aLfiZZle]

hi, looking for some knowledgeable advice on a unique situation... I have a 96 i30t . About 5 months ago the engine blew due to a cracked radiator and overheated bad. The car sat for about 4 months until i finally had an engine swapped. after installation we doubled checked all wiring, and attempted to start the engine with no luck. i read on these forums to check for spark, compression, and fuel. i checked the fuel by disconnecting the line from the filter to the regulator. Fuel flowed out as i attempted to start the engine. Checked compression 179 on all cylinders. no spark however. The car continues to crank but will not start.

i took the car to a shop that has some nissan scanners and he says there is no signal to the injectors and no signal to spark. He says it cant be the ECU because he has communication with it. Im wondering if anyone has ever seen this problem after an engine swap or maybe the ECU needs to be reprogrammed or what... Oh and he changed all the coils and crank sensor checked fuse etc. Any info will be greatly appreciated!!!

Get them to give you the exact codes so we can help you better. When you pull the codes look them up here: http://www.nicoclub.com/articles.php?id=60332 and if you need more help look them up on Google. Your kind of lucky that you have OBD2 because its easier to find the problem.

As Paul mentioned, you need to get the specific fault code for proper diagnostic. You may have DTC Code 1320, Ignition signal. Since your mechanic already changed the coils and crankshaft position sensor, you can ask him to check the condenser (1 Meg-ohm at 77 degrees F) and double check on the harness-connectors. Also, check and if possible clean the ground wires on top of the engine, besides the intake plenum, near cylinder #2.
