If my timing is off 45 degrees on the distributor cap will I still get fire to the spark plugs?

Asked by May 10, 2016 at 11:38 AM about the 1999 Chevrolet Tahoe 4 Dr LS SUV

Question type: Maintenance & Repair

I recently had my O2 sensor wires melted to my
exhaust. Right around the same time my truck
backfired and apparently jumped timing. I went
back to fix the wires and correct all that now my
truck won't start anymore. I got up under  the hood
and  found out that I wasn't getting fire to my spark
plugs. Ive replaced spark plugs, wires, distributor
cap, rotor, ignition sensor, coils, camshaft
positioning sensor, and still have no fire to my
number one spark plugs I was wondering if maybe
my timing being off that far if it could possibly
affect me not getting spark?

What are the trouble codes? I am concerned about the backfire and the fact that it shifted the timing that far off, it is possible that it jumped the cam timing as well due to a worn timing chain. I would do a compression test too see if it is low, if it is then a timing chain is a real possibility. Any way if all that checks good then the computer controls the spark on this rig, with the distributor that far out you should be getting a sync signal code, bring number one up on TDC on the compression stroke and reposition the distributor so the rotor is on number one firing tower location, this just a ball park setting to get it running and the dealer can realign the cam sync with the crank sync signals later on, or if it runs good and no check engine light about the sync signal then you don't have too.
