92 RS Wont Start

I am new here and need some help bad. I just did a basic tune-up, plugs wires cap rotor and reset timing to 2 degrees retarded. Now the car gets hot and the fuel stops flowing to the TB. Any body got an idea ????

Try advancing your timing first, there's no real advantage to retarding your base timing below 0*

That was my fine typing skills it is actually about four advanced. Spark is great the fuel just stops at the injectors. I am starting to think it is the relay...

Change fuel filter (although that probably isn't your primary problem).
Check the relay, there's prolly where your problem lies.

if it's the relay you will still be able to start it just crank it for a few seconds 8x's or so and it will start, it won't get fuel until the engine makes enough oil pressure because, of gms oil pressure switch or as i like to call it *the anti crash and burn switch*

If you'd rather not crank it so much then swap the fan relay which is directly next to it with the fuel pump relay and it should fire right up if the relay is your problem.


anyways i wouldn't even look at the relays if you can hear your pump click on when you turn your key to the on position.
