Well my 90 Ford quit running again. Cranks but doesn't start. Replaced the tank switch just in case. I have a fuel pressure gauge and spark tester on the way. I'm thinking the rear fuel pump went out. Front has been out.
With the key on, push in the schrader valve at the back of the fuel rail. See if fuel comes out with any pressure behind it.
Ok. About to try it. What kind of tool is safe to use to push it in? Need to be plastic or something to avoid damaging it?
Sure. Plastic wood or just your fingernail
