89 305 tbi problems

It starts and runs for a second and dies, acts like its loading up and running rich. Changed and or checked pretty much everything I could think of, plugs, wires, cap, button, injectors, module.
Any ideas?

Timing maybe? How easy does it start?

 

[Foxpak]

Starts pretty easily, just won't stay running for longer than a few seconds.

Did you change the cap or just check for cracks? If you changed it are you sure you re-installed the plug wires to the right spot on the cap? Your firing order could very well be off, which would cause a major timing issue like it sounds you have. Also have you checked the mag in the distributer? Or the coil module? Both of those could also attribute the same type of problems your having!

Check it for codes

right beside the thermostat is the coolant sensor for the computer, try unplugging it and see if that helps. if that is reading way cold it will make the computer dump way to much fuel

How old is fuel pump? Check fuel pressure.

M O O N , that spells "check your fuel pressure". Laws yes! It does!

Timing and firing is right, fuel pressure is good, bypassed coolant sensor. No change.....
No codes either....

Your absolutely positive about the timing and fuel being good?
