Bought a remanned longblock 5.7 for my sons truck. After days of painstaking install, we can't get it to fire off. Its at TDC when we install the distributor. It got late and we quit for the night.

I know there's a method for timing it once its running but we ain't there yet.
Any suggestions?

Thanks
 
Do you have a scanner that shows live data if so check to see if it is showing a tach signal and timing retard degree

Ill post the instructions on distributor install, I've seen quite a few folks have trouble with line up and not understanding pickup operation.

  1. Align the indent hole on the driven gear with the paint mark on the distributor housing.
  1. Ensure that the distributor rotor segment points to the cap hold area.

  1. Align the slotted tang in the oil pump driveshaft with the distributor driveshaft. Rotate the oil pump driveshaft with a screwdriver if necessary.
  2. Align the flat (1) in the distributor housing toward the front of the engine.
  3. Install the distributor and distributor clamp.

  1. Once the distributor is fully seated, align the distributor rotor segment with the number 8 pointer that is cast into the distributor base.
  2. If the distributor rotor segment does not come within a few degrees of the number 8 pointer, the gear mesh between the distributor and camshaft may be off a tooth or more. Repeat the procedure in order to achieve proper alignment.

Ok thanks, I've found this info on line also. As it turns out our distributor is in correctly, looks like the crank sensor is bad. Getting another today and will hopefully get this thing running.
 
After a fun filled day of chasing this, I started over and rechecked everything. The crank sensor that I bought today was bad so I traded it for a new one. I now have spark! Too late to get it all back together tonight for my boy's first day at school as a driver, but another few hours on it tomorrow and he will be in business!
 
I get off work at 3 if you need a hand just let me know
