Has anyone suggested to turn the crank such that the cylinder #1 is at top dead center, then checking to see if the distributor is pointing at #1?

The only way to properly fix it was to completely break down the engine again, so we sent some folks we knew down the road with backwards distributors. |

If you left the plug wires where they are supposed to go, this is exactly correct. The engine would not run at all because when the spark hit, the exhaust valve would be about to open.

If what I think is going on, is actually what is going on, that won't work in and of itself. The distributor will be pointing at number 1 at the top of the exhaust stroke instead of the compression stroke. You would have to take the valve covers off, and watch the valves to make sure you were at the end of the compression stroke on number 1, then see where the distributor is pointing. My guess is it will be pointing at the 5th cylinder in the firing order, which for my engine would be cylinder #6.

I’m sticking with yes it would run but not right….The wires would have to also be 180 off. Fuel is batch fed to each bank, they’d fire.

Gene, you probably don't have your timing right off the distributor and I still think you don't have your valves set correct, either. |

The drive bone connected to the cam bone, the cam bone connected to the valve bone, the valve bone connected to the dizzy bone, an I hear the word of the Lord.

If it turns out to be a bad distributor, I have a new, lightly used HEI I bought for my 454. I used it to break in the motor, and was going to use it in my 47 Olds, but it's too big and hits the firewall so I put an old points distributor in it. It's a cheapy Ebay one, but you're welcome to it. Consider it an early Christmas present. If you want it, just shoot my a pm with an address

My kid had a program on his cell phone to read codes. Still need to buy the cord to plug in though. No idea how he got that but it did what it was supposed to. Might be an option for you if you've got one of those newfangled contraptions.

WELL, I flipped the rotor cap around 180* and so it backfired like a shotgun/270 win combined....woke HELL outta the hood.......
oh well, maybe it blew something else back into place.....put it back to 'normal' and engine started/ran same way...... so back to the mystery chart.....me thinking of pulling the damn China made injectors and examining them with a BRIGHT light and a mag glass and reverse pressure blasting with air.....they not been off the manifold since maybe3 years ago..... |

We've only been telling you your valves aren't right for weeks and they way you are doing it obviously isn't working. |

Start is up and remove one plug wire at a time. If you pull one plug wire and there is NO difference in the way it idles that is your problem cyl. That cyl. ain't firing in the hole. Do you have a fuel pressure gauge? And what psi are you getting at the rail? Fire it up and turn dizzy a little each way and see if it smooths out. Again, check your firing order and plug wires. MAKE SURE YOU DON'T HAVE ONE OR MORE GOING TO THE WRONG CYL. |
