Just got finished putting my motor back together with a 89 5.0 block and now im trying to get it started. The starter engages, the crank turns over, and I know the cam timing is correct. My question is on a old car I know that for the firing order you put the harmonic balancer at top dead center and get the distributor rotor to point towards the number 1 cylinder then start the correct firing order from where the rotor is under the cap. On my mustang I tried doing that and I can't get it to start. Is it different on my car compared to a older car? Any help would be appreciated, thanks.
