it doesnt have one, you need special tool to check atual pressure.
behind the throttle body, there is a quick connect. Just disconnect the quick disconnect, and see if fuel squirting out. Just make sure no one is smoking around you while u r doing this, LOL. if it does(or doesnt), get an extension hose of some type (like cut up gardening hose) and shove it into the fuel line from the pump, and have your wife turn the key ON, see if any fuel is pumping out.

another thing you can try is use a plastic mallet to whack under the gas tank while ur wife cranking the engine. Sometimes the fuel pump would start working after you bang on it. If it works after u whack it, that means u need fuel pump.

 

Don't wack on it too hard! :-)

When you disconnect you want to see it squirt not just dribble.

Dribble bad...Squirt Good!

 

I was all ready to keep gas from spraying around my engine. Unfortunately, I didn't even get a dribble, let alone a squirt. It's looking like the pump is toast. I'm going to check for voltage at the pump itself. Already checked it at the IPM, and it was good. Does there happen to be a filter anywhere external to the tank that could be clogged?

 

Finally had time to get back to my van. It turns out that the wiring harness to the fuel pump was shredded. It was rubbing badly against the white handle on the gas tank and broke a wire. Unfortunately, I still had to drop the tank to have room to splice it and put some flexible conduit around it, but it's a lot cheaper than buying a fuel pump.

Here are a few insights that may be helpful to anyone else looking to drop a gas tank for the first time.

1. The $2.99 siphon from Autozone doesn't cut it. The tube was so flimsy I couldn't even get it down into the tank. I ended up dropping the tank with about 6 gallons of gas in it. There's got to be a better one out there somewhere.

2. The filler hose was very difficult to remove from tank. It may have been because it was so cold here, but I had a heck of a time getting it off. Recommend you disconnect the rest of the fuel lines prior to trying to remove it. I was really pushing and pulling on the tank to loosen it up, and possibly would have damaged the other lines in the process.

3. Definitely have some way to help lower and raise the tank. I mad a jig with a piece of 2x4 that I attached to my floor jack. It supported the tank in one direction, but I could've used some help in the other direction. I can't imagine dealing with it with anything less. Even re-installing it after I removed the gas was very clumsy.

4. It might be a good idea for anyone with a GC to look up under the back to see if their wires are being chewed up. I was amazed at how bad it really was. It's just behind the tank, under the trunk area. Easy to see without even putting it up in the air.

Also, thanks to everyone for their insight that got me to that point.

 

Glad you got it working and figured the problem out
