Re: whats wrong?
I think that is the tach lead, but it's been 10 years almost since I had a TBI truck. (that ran!!!!)

Re: whats wrong?
Check the timing. Have you looked at the rotor?

Re: whats wrong?
Pull a wire and check for spark .......if you have spark squirt a small amount of fuel in the intake ...if it fires for a few seconds it is a fuel issue.
If you have spark and fuel and still no fire you have a mechanical issue....timing chain??? |

Re: whats wrong?
I agree. I 'd check the fuel filter also. Always check the cheap and easy things first.
