Can’t get my 454ss to start with a Sniper
I had issues with fuel pressure on my Holley Efi system (on my 1990 454ss), well after sorting that out I still had no start so I removed and re installed the Hyper spark system (I knew I was getting fuel) redoing the timing the exact way Holley demonstrated. Well now when I turn the engine over fuel shoots upwards and will either ignites causing a big flame or causing smoke to come out of the intake manifold. I assumed it was timing and completely redid it again but I’m not exactly sure what I’m doing wrong as it’s still causing that. I remove cylinder 1’s spark plug-rotate to top dead center by getting it to the 0 degree mark on the compression stroke and feeling the top of the piston with a pick-I then install the distributor making sure it seats with the oil pump so it seals against the intake manifold pointed at the second bolt on the manifold and having it pointed at cylinder 1 once seated-I used the Holley clear install tool to line everything up and find plug one on the distributor-reinstall plug wires in the correct firing order and try to start it
I’ve also made sure I have constant 60psi of fuel pressure so it’s not spiking or dropping. I’m lost at this point any help is appreciated
