Pour a little fuel down the TB. Does it run for a few seconds? If so you have a fuel pressure problem. TBI's are very sensitive to fuel pressure loss.

If you have spark and fuel then I would say check your firing order again, or maybe somehow your timing got messed with during all the work you did.

Air in the line shouldn't be a problem, the regulator sends excess fuel back through the return line and that should purge the line.
Check your ignition - you probably have something wrong. You swapped a lot of stuff, there's plenty of room for error.

+1... and why I do plug wires one at a time

Did you put oil back in it? Fuel pump wont turn on until oil pressure switch has pressure on it.

franky69c10 · 02-16-2011, 04:47 AM

^^^
Yeah that was the first thing I did was change the oil, when I got off work 2 day I messed with it but no luck

should I check the oil pressure switch
