Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im David, sorry you're having issues with your vehicle. The very first thing that needs to be done is a compression test of all the cylinders. with the scenario that you have described, it is possible and likely that a.) you blew a head gasket b.)you cracked a head c)you bent valves.
yes, that would keep the vehicle from starting. a compression test is done by disabling the fuel system by puilling the fuel relay. removing all the plugs, installing a compression test gauge into each plugs hole(one at a time). cranking the engine over 5 cycles with gas pedal to the floor. then resding the gauge to see what thecompression of the cylinder being tested is.
