so just recently i got 91 civic hb cx with 1.5 engine (D15B2) There was a leak on the head gasket so i asked my mechanic to replace the head gasket, We know for sure that there is no leak on the pistons because we checked the pressure before we started the job. Since he already removed the head and we can easily replace the transmission we included it in the job. we replaced the thermostat, timing belt, water pump, and the alternator belt. as we try to start the car, it cranks but it doesn't start. so we checked the pulse, and found out that there is no pulse on the out from the distributor, so we replaced it with a new distributor (td-u10 if im not mistaken) ohh before we replace the distributor and tried starting the engine, the main relay started buzzing. no idea what just happened because it never happened to me before we did the job. now we are stuck because engine doesnt turn over and we are pretty sure that we got all the ground connected, that there are fuel pressure, starter is working and the wires, the spark plugs are new too. i recently replaced the fuel filter too. i dont know if it matters but my EF has the Dual Fuel Injector. Please help out! car is in the garage for 2 weeks now since we started the job. batter is fairly new too!
