Leaking dutch doors by iahawkeyemn

I have a 200o Chevy Astro and I have noticed the dutch doors appear to leak during a hard rain. This is espically noticeable on the passenger side. I have seen previous posts about this problem. What is the best method for resolving this problem?

After replacing the cap, rotor, plugs, wires, fuel filter, and checking the coil and EGR valve, I decided to tow it into the dealer. I really hate to be in that position. I suggested to the dealer to check the fuel system since it appeared to run better after I replaced the fuel filter. He finally isolated the problem to a failed fuel pressure regulator. So my van has been spared from the scrap heap once again. I think maybe some of the black plastic and metal flecks that I found in the fuel filter belonged to the pressure regulator. It was one of those situations where I did not have the right tools or insight to find the problem myself.

I understand your position, that's a pretty complicated undertaking to take apart that plenum and injection system. Because without the proper tools it would be really hard, but good luck it'll probally run better than it ever did when you get it back if they replace everything which is what I do if I go to the trouble of disassembly.

Well, the replacement of the fuel pressure regulator did not solve it. I purchased a new fuel pump which the dealer is installing today. If that does not fix it, I'm giving up. So far the dealer has run up an $800 bill chasing dead ends. I wish I could rewind, since it is a lot less costly for me to be chasing dead ends. He claims the fuel pump is not putting out enough pressure, and that the fuel pressure leaks out when the fuel pump stops. My experience has been that when a fuel pump dies, it is sudden, not this costly lingering agony. But I don't have a fuel pressure tool in my tool box. Maybe next time I will. More to follow.

I think he might have got you there, the fuel pump pressure should have been checked first thing, and it actually sounds like an open EGR valve which will probally be next on his list;and that to should have been checked first because a little piece of carbon in that EGR valve causes those Astros to run like crap and their notorius for it. The fuel pumps usally just go out they don't usally lose pressure they either work or they don't. I've only seen that happen very,very seldom. And loke you said they usally just go out they don't lose pressure, I think you might being getting played for parts you don't need and they will keep it up as long as possible. I would ask to see the low pressure reading, if it's there at all which I kind of don't believe. DLM1954

Ok Lads the real answer to the riddle of wiper troubles. This is always the root cause.
The wiper motor Ground strap is located under the mounting leg near the hood opening at the windshield. This strap is used as the ground through the bolt and the body. Vibration will cause erosion of the metal and the strap causing bad grounding.
Thus intermittent operation. The cure is to thread the unused hole on the upper right of the wiper motor and install a Tap bolt and soldered wire clips to a good ground on the firewall. No more wiper troubles!!!!

I know this is a long time after this post. But I have just bought a 2000 Safari and am having thumping noise when I ease off.. Is there a way of checking brakes It does sound like it is on the passenger side.
Any help would be appreciated

'92 Safari with random ticking noise by gstrand
Nov 11, 2008 (8:20 pm)

I'm hoping someone has an idea what may be causing the random ticking noise I hear that seems to be coming from the area near the catalytic converter/starter motor. The noise is apparent in park, in drive at low speeds below 45, and at idle. It's a fairly rapid tick, anywhere from 3 times a second to maybe once every 2 seconds, but there is no pattern to it. This rig has 208,000 miles on it and starts and runs beautifully. It has been a bullet proof rig but this noise has me baffled.

fuel pressure on an '04 by the_big_al

I need to change the fuel filter on my van. Is there any way other than removing the center engine cover inside the van to relieve the fuel pressure in an '04 Astro?? I looked for the pressure relief valve, but it must in the same spot as my S-10. On the S-10 I can get to it no problem, but on the Astro that means it is buried back up in the engine bay. I really don't want to take the whole cover off inside the van for a 2 minute job. I also don't want to just start undoing the nuts on the fuel filter. I have this phobia of changing fuel filters (the last time I did it on my S-10 I came away with a nose, mouth and earful of gas) and want to make sure all the pressure is relieved from the system.

There also was a service bulletin on the power connections for the motor which solder right to the circuit board, the solder cracks (cold solder joint). The circuit board is just under the black cover on the wiper motor. It happened to mine and I pulled out the weller and resoldered the pins and wau la, no more problems.
