How to check fuel pressure? No tester.

[gijoe985]

I'm 100 miles from my shop and am going to be looking at a car with a theoretical bad fuel pump. I am going to check for engine codes, if I hear the pump starting up, and if it is getting voltage. If it is getting voltage and sounds like it is starting, how can I check pressure without a tester. Just to know I'm getting something? Just pull the plugs and see if I get something in the cylinders?

that will work to an extent you wont know the pressure but you will at least know your getting fuel.

Yeah, I'd just like to see the fuel if I can hear the pump starting. That will give me some direction.

i would pull off the fuel line and see if you got gas coming out of it , before resorting to checking the pressure. i know auto parts stores usally carry fuel pressure gauge kits. might want to stop and pick one of those up.

Already own a test kit, I'm just away from home right now. And withe the fuel pressure these cars should produce, I'd hate to have the line off with it working. I think by doing it in the cylinder it will be less, and more controlled.
