Well the trucks running but it still needs an 02 sensor and the adapter I got has a vacuum leak. I have a steel plate on the way

If it's backfiring that bad, sounds like the timing is way off.... good luck and let us know when you discover what the problem is.Well ive ran the truck tonight and I still have some issues to work out. At the moment it only revs to 3000 rpm and I had a huge fireball out of the tbi so I've got to figure that out. Tires will hopefully be here tomorrow. I haven't messed with tbi in years so this will be a learning curve.
That's what I was thinking but with the timing port disconnected it still shows zero where I set it with it plugged in it's adjusting timing. How much it's adjusting I'm not sure I haven't put a dial back light on it yet all I have is a standard light.If it's backfiring that bad, sounds like the timing is way off.... good luck and let us know when you discover what the problem is.
Check the damper/balancer whatever you want to call it and confirm it hasn't slipped on the rubber vs the tab on timing cover and #1 at TDC. Trust but verify the marks are true telling you that the base timing is zero.That's what I was thinking but with the timing port disconnected it still shows zero where I set it with it plugged in it's adjusting timing.

I wouldn't think it would have slipped. I built the engine 600 ish miles ago and I used a new balancer.Check the damper/balancer whatever you want to call it and confirm it hasn't slipped on the rubber vs the tab on timing cover and #1 at TDC.

Don't waste your money on a dial back timing light. I've bought both inexpensive(cheap)and expensive(still cheap) timing lights. They all lie!!!!! Now I rotate the engine counter clockwise until the timing mark on the balancer lines up with the 10deg. mark on the pointer then scribe or paint a mark on the balance at the zero mark on the pointer. Now your balancer has a 10deg. mark. Rotate the balancer counter clockwise until that 10deg mark you made lines up with the 10deg. mark on the pointer and make another mark on the balancer. That's your 20deg. mark on the balancer. Keep doing that until you have as many 10deg increments as you want. 50deg. should be all you'll ever need. When you read it lets say your 20deg. mark is 8deg. advanced of 0, you are reading 28deg. of advance. They sell timing tapes to apply to your balancer but I've never used them. Not sure how accurate they are or how well they'll stay on there. The only other option is to buy a balancer with degree marks all the way around(like FluidDampers)but they are pricey and all those other marks are not necessary unless your doing something exotic with the engine.That's what I was thinking but with the timing port disconnected it still shows zero where I set it with it plugged in it's adjusting timing.
