Default Non running 1984....

Hi Guys,
I'm looking for some ideas.... My 84 will start if I prime the trottle body, then dies. No fuel to the TB. Where to go from here?

Thanks
Bob

Start with checking your fuel filter it may be clogged. If that isn't it the next thing to start doing is test the operation of your fuel pump.
When you turn the key to the on position (not start), do you hear the pump turn on?

I opened the supply line to the TB. Then turned on the ignition switch to run, the pump pushed gas through the fuel line. I dont think its the filter, but no gas seems to be in the TB. Do they have filters in addition to the in-line filter on the frame? The car ran fine but as I was driving allong it quit never to start again, without priming.

You want to measure the pressure of the fuel lines. On a CFI that should be 9-13 psi. You can use a temp fuel gauge between the 2 Tb's.

Just because you have fuel coming out doesn't mean you have the correct pressure.
The only filter on the system is that one on the frame rail.
