Well the fuel pump for a 4 cylinder is about $270.00. Depending on there labor rate this may be a reasonable estimate but it does sound a little high. The six cylinder pump is around the same price. If you can find someone who knows how to drop the tank then you can eliminate some of your labor cost. So $740.00 for labor thats a rip off.

I just had a fuel pump replaced on a 2000 23' Class C motorhome with a Ford V-10. It cost me approx $1400. The mechanic claimed the fuel pump was a special order item from the dealer for motorho

Don't know what the problem is here...nothing stated. 1400 for a fuel pump repair seems a bit high but I don't know what the part cost is. I am just throwing out a ball park here (without ever having worked on the particular vehicle) but i would say this would be estimated at about a 4 hour job. Shop rate probably 90 to 120 so on the high end for labor 480. Now check on the price of the fuel pump. Check online sources such as Carquest, Napa or ORielly.

What are the most common problems with this vehicle.

According to

Occasional problems on this vehicle are plugging of the Exhaust Gas Recirculation (EGR) Valve Passages (2.4L engine only) and failure of the Fuel Pump Sending Unit Assembly Connector Terminals. Plugged EGR Valve Passages may cause the engine to misfire and may also cause the Check Engine Light to illuminate. Failure of the Fuel Pump Sending Unit Assembly Connector Terminals can cause loss of power to the fuel pump leading to a crank and no start or an engine stall while driving. A periodic problem on this vehicle is failure of Distributor Assembly (3.3L only). The cost to repair the EGR Valve Passages is estimated at $10.00 for parts and $130.00 for labor. The cost to replace the Fuel Pump Sending Unit Assembly is estimated at $206.41 for parts and $195.00 for labor. The cost to replace the Distributor Assembly is estimated at $370.00 for parts and $39.00 for labor .All prices are estimates based on $65.00 per flat rate hour and do not include diagnostic time or any applicable sales tax.

Cost of replacing fuel pump

Since this vehicle, (1994 Plymouth Voyager), is fuel injected, the fule pump assembly is located within the fuel tank. Replacement cost will vary, depending on your ability to lower the fuel tank and replace the part yourself. The fuel pump assembly ranges in price, from $95, to $140, depending on where you purchase it. The particular parts suppliers I use on a regular basis have listings for the fuel pump assembly, so finding a replacement part won't be hard at all. Though I haven't replaced a fuel pump in this exact vehicle, typically chrysler/plymouth/dodge, vehicles don't require any special tools to disconnect fuel lines, electrical connecters, and remove assembly from tank. Note: if you do this yourself, do NOT, cross-thread the pump locking ring, if it is a screw on type, as this WILL result in fuel leakage! If you have to have a repair facility do this work, I would estimate about 200 dollars in labor charges, (that's what I'd charge a customer in my shop) So, you should be looking at no more than $350, to $400 max with part and labor.

The gas guage does not work on my '97 S10 pickup (it shows about 3/4 tank.) Is this something I can fix myself ? If so, what parts do I need and what will it cost, approx? If NOT, how much will it cost to...

The level sensor in the tank has gone bad. You can buy a fuel sending unit for about $100 (you used to have to replaced the whole tanks for hundreds of dollars, but they had so many issues they started selling the sensors on their own).

You can fix it on your own, but you're going to want the tank to be pretty much empty before hand.

Here is an example of replacing one on a S-10 blazer. Should be similar for your truck:

2000 GMC Sonoma will not start after standing serveral hours

Check the fuel pressure at the shredder valve, you should have 62 to 65 PSI when the fuel system is primed. (engine not running) With the engine started and running the pressure should drop by 5 PSI, anything less then 62 PSI in your fuel system when trying to start the engine will cause a no start. Note; that try to start a the engine by pouring gas through the throttle body may cause an internal fire in the intake ports and will cause the fuel injectors to melt creating a more expensive problem. As for the fuel pump in the gas tank, it''s held on by and snap ring which you can remove with a simple screw driver. Good luck and keep me posted, and don't for get to replace the wire harness from the frame to the gas tank. It's a $12.00 investment that's worth more then it's cost.
