I just replaced the head with a 92 metro head. After switching the timing pulley everything seemed to match. I'm positive the timing belt is spot on. I've checked and rechecked my wire hookups and everything is connected. Out of desperation I replaced the ignition module. The engine starts without a problem, but after about 2 seconds it dies. If I keep cranking it won't fire again. If I let the key turn back to "on" then try again it starts then dies. Any ideas?
