Hi, today my Safari just cut out on me while I was driving. I towed it to Pep Boys and they said that I have no fuel pressure and not enough sparks. They said I need to replace the fuel pump, fuel filter, relay, air filter and get an oil change. The total cost would be $1133. That sounds crazy to me just to get it running again. They said I needed some other things too like a tune up and transmission service. Please help. I got the car in March and have been used by dealers before on other cars.

I have no experience with Pep Boys but it sounded like one of those chain stores that employs high pressure sales reps. From what you've described, I won't let them touch my van with a ten foot pole. I believe the main cause for your cut-out is either no fuel or no spark but not a combination of both. If your fuel filter is not badly plugged, which can be tested without major work, it would be a faulty fuel pump. If you turn the ignition key to the on position, you should be able to hear a hum in the fuel tank area to indicate the pump is working. Knock the side of the fuel tank with a rubber mallet will sometimes get it going temporily so that you can drive it to another garage for a 2nd opinion. But if it is the culprit, you are out for some major expenses because it is located inside the fuel tank and is packaged with other components. Search this forum on discussion re: fuel pump will give you an idea about reasonable Re & Re cost in you area. You may due for a tune-up but I don't believe it is necessary to get it going for now.

Try asking the folks in our Maintenance & Repair Forum -- there are two discussions there -- Maintenance & Repair Costs and Fuel Systems Maintenance/Repair that might be helpful.
#1038 of 1973 '94 2wd Astro Problems Please Help
Sep 09, 2005 (9:59 am)
Ok here is the deal with this very troubling problem I am having.
Astro Van '94
When I am at a speed in excess of 50mph this problem accurs.
At any speed above 50MPH when I take my foot of the gas and the vehicle begins to slow down I get a low pitched rumbling sound that sounds like it is coming from the rear of the car. It also feels as though something it's holding the vehicle back and not letting it run as smoothly as normal. Once I hit 80MPH the vibration and sound is constant when my foot is on the gas. The sound and vibration only occurs for the first 5mph of decceleration. So if I am doing 70mph and take my foot off the gas I get a low pitched rumbling sound (rumbling, grinding, mechanical type sound), a slight vibration, and it feels as though the vehicle is hesitating.
So far I have:
Changed the universal joints.
Checked the rearend and the fluid seemed good (I replaced it) and there was no metal shavings at all in the fluid, or on the magnet.
Checked the trans, fluid seemed alittle burnt, replaced the fluid and fluid filter, gasket all that good stuff.
Had the tires rebalanced.
Problem is still there and I can't figure it out. Neither can anyone I have talked to already.
Has anyone has this problem? Anyone have a clue as to what it is? Help.......

94 astro barely runs if at all, refuses to start at times. reminds me of when i had to replace the fuel pump in the tank...man was that expensive! I wont do that again, which leads me to ask, can i put an electric pump in to assist the tired tank pump, somewhere in between th tank and the engine? any thoughts...thanks

I would think you could mount one just outside the front of the tank to the existing line. You should probably wire it to a toggle switch on the dash to turn it on and off and disconnect the one in the tank that is not working correctly. I am not sure if you can get the gas to run through the bad pump. I had a Holly electric pump on a 1979 Camero that was wired to a switch and it worked great. Make sure you have a fuse in line.
#1042 of 1973 94 astro / bad fuel pump
Sep 13, 2005 (10:22 am)
has anyone replaced the fuel pump in the tank? what is the procedure? any special tools?
The van is not worth the money to have the dealership do it...so I must tackle it myself.
Any help is greatly appreciated!

I didn't work on mine but watched my mechanic doing it. You have to drop the gas tank. It'd be tricky if your tank is rather full and didn't have the use of a transmission jack. The fuel pump is located on the top side of the tank. Replacement seemed straight forward except you'll have to be careful when disconnecting the fuel line. It's pressurized even when it's not running.
