1997 buick lesabre custom: new starter, new battery..fuel filter..coil

Customer Question

I have a 1997 buick lasabre custom 3800 and i put in new starter, new battery. c-noid, fuel filter, fuel pump and 3 coil seem to be working. got fire on all plugs. All plugs gapped correctly. Dropped manifold and put back on after putting starter motor on. Did 10 minutes of 15 min. blue devil treatment for blown front head. White smoke stopped in about 5 min. And started it 2 times after still no smoke. I let it run and after about 10 it quit. I think I ran out of gas. So I put 5 gal in tank. Tried to start it again and it wouldn't start. My back yard neighbor mechanic had pulled the vacume lines without marking them I put them back with my best quess and now it won't start. I tried to find a pictIure of how they go back on. With no luck. It tried to start but backfired thru the exhaust. What could be the problem? And where can I find a picture of how the vacume lines go back on correctly?

I have a curved black metal hose connector with 2 lines that my neighbor took off and never put back on and can't figure out where it goes.....so made my own lines.....can't figure out how it goes back on with the diagram that u sent....

would that keep it from firing up?

Customer: replied 5 years ago.
Do u have a better diagram ? I've tried the hoses different ways and it still won't fire up. It backfires....

it's been 2 hrs...is anyone going to answer?
Expert:  Dave Nova replied 5 years ago.

Sorry for any delays, had family needs. If there are any open vacuum ports, this could cause the engine to run rough or idle high, but won't usually cause the car not to start. Will the engine start with starting fluid?

Customer: replied 5 years ago.

No the starting fluid didn't help. why would the car backfire thru the exhaust? could it have any thing to do with the plugs? Could it have jumped timing? I checked the # XXXXX and #5 cylinders after i changed the plugs and gapped them.

I'm sor

Expert:  Dave Nova replied 5 years ago.

The best thing to do at this point would be to perform a compression test on each cylinder. This will indicate if there are any mechanical problems like jumped timing, etc.

Let me know what you find.
