Question about 1988 Chevrolet Suburban

1 Answer

Can you access the fuel pump without removing tank? Im not getting fuel to the carb. I checked the lines to the fuel filter to carb and from fuel filter to the tank and seems clear. The only thing I can think of is the fuel pump. Any ideas? Also, can you access the fuel pump through the rear of vehicle inside or does the tank need to be removed?

If you have a carburetor, you have a mechanical fuel pump on the engine. If you have a throttle body injection your pump is in the tank and the tank needs to be removed to get at it. Before dropping tank make sure the pump is getting power and a good ground.

2004 Honda Element 4 cyl. has new fuel pump but will not pump gas up to the carb.

I'm not familiar with your vehicle (but I've just spent an afternoon fixing a similar problem on a Fiat..). It's an electric fuel pump?

Ok. There was some reason why you had a new fuel pump fitted in the first place .. had the vehicle been slowing down/cutting out? That is a symptom of a faulty/failing fuel pump, yes.. but it can also be other things.

The fuel filter was replaced? A blocked fuel filter can cause problems, though it's unlikely that no fuel would actually get to the carb.

Can you remove the gas filler cap and disconnect the fuel line where it enters the engine bay and get somebody to turn the ignition on? Fuel should literally spurt out. Removing the gas cap and disconnecting the fuel line will purge any air in the system. removing the gas cap also allows air into the tank and prevents a 'partial vacuum' which restricts fuel supply.

If you disconnect the fuel line and switch the ignition on you should hear the in tank electric fuel pump working.

You mention carbs ... Does your car have injection or carbs?
If it is a carb model .. a sticking fuel float will cut off fuel supply into the engine.

Your first action should be to disconnect the fuel line somewhere in the engine bay, and turn on the ignition. If fuel spurts out the problem lies in the injector/carbs.

If no fuel comes out the problem lies with the pump/tank.

There is a filter on the lower end of the fuel pump so it don't get particles in the pump from the bottom of the tank. That is if any is in the tank. Normally you will have a fuel filter in the line between the fuel pump and the throttle body or carb. In addition, if a carb is on the car there is a fuel filter where fuel line connects to the carb. You would need to disconnect the fuel line and then take the large nut loose on the carb and the filter is there.

1984 Chrysler new Yorker 2.6l wont start. Replaced the fuel filter, new spark plugs and wires, new fuel shut off switch, new relay delay fuse, and a new ignition coil, oh yeah and a new starter. Ever hear...

Here's a quote from amy Chilton's manual for 1980-1987.

"Several types of fuel filters are used. One is located in the fuel tank of all the vehicles and is part of the fuel guage assembly. Second is a sealed paper element, in-line unit; mechanical system- located on the engine (above the fuel pump) or electrical system- located in front of the fuel tank. Third is a paper element, in-line fuel filter/vapor separator, housed in a fuel resevoir. Normally, the in-tank filter does not require changing. If it does, the fuel tank must be removed. "
This thing you describe sounds like the typical Chrysler in-line filter of its day. It is nothing more than the same generic in-line plastic see-thru filter you buy for your lawn mower except in the 70's and 80's it was covered in metal and had a Chrysler part number. A lot of guys added an extra filter in those days, it wasn't the best system. I would remove the outlet line and turn the fuel pump on, see if you get fuel. Replace if needed.

Engine will start and run for 2-3 sec and die

Fuel Pump went out or a problem with the ECU but 98% of teh time, it is the Fuel Delivery System. The Fuel Injectors require 40 PSI to operate correctly and if the pressure is below that, your car will not get enough fuel to run and will DIE after starting...

1979 holiday rv chevy 454 no fuel to carb i replaced fuel pump filters fill carb with gas engin runs then no fuel to carb

if it has been sitting for a long time you may have to dis-connect the fuel lines at both the tank and the pump and blow air through to see if there is a blockage in the line. if that is clear then make sure all fuel hose's are in good condition and not collapsing from old age. if those are in good condition then there is a problem in the tank and it will have to be removed for inspection....

How do I check fuel pump w/o dropping tank on 97 stratus

filter ? or the new fuel eats the line off the pump in the tank. if you hear the pump in the taank running there is a good chance it's the pump lines in the tank. there might be a access door under the seat or trunk that will allow you to service it without removing the tank = no fun.. some dodge vehicles the only filter they have is in the tank ! krazy !!

Need to get fuel to 85 chevy cube van, i replace the fuel pum and smog pump,getting no gas to carbuerator.

You have two filters in the system. One is in the fuel inlet on the carburetor, the other is the "sock" inside the tank. If either is plugged, no fuel will flow. Also examine the fuel line. Unlike an injected system, a small hole in a line often won't leak a lot because the pump pulls fuel. A hole will allow air to be pulled in instead of squirting out fuel. First, remove the line from the carb and attach it to a hose and crank the engine. After cranking, you should have about a pint or fuel in the catch container. If not, check line and tank filter. If you have fuel, check carb filter. On Chevy engines there is a rod inside the engine that operates the pump. You did make sure that the rod was up and the pump arm is actually being activated by it?

Can you replace an inline fuel filter without replacing the whole gas tank?

the in-line filter is in the fuel line between the tank and the engine, seldom do you have to even touch the tank much less remove it in order to replace that filter. there is a screen on the pump inlet of the
in-tank fuel pump and most likely you are going to have to drop the tank in order to replace the pump or the fuel level sender. make sure there is not a service access hole in the rear of the car such as under the spare tire which could give you access to the top of the tank. on the other hand it is not unusual to find yourself in a situation where a lot of the fuel line must be replaced when you replace the in-line filter. as such you may find yourself with no room to connect the new fuel line to the nipple on top of the tank, without lowering the tank a bit.

1987 jeep wrangle will not start or run

Uncouple the fuel line coming from the pump at the carburetor, place a clean can under the line, and have someone operate the starter--you should have fuel shoot from the line in spurts as the engine turns. If it does, then the entry port on the carburetor is plugged. Remove the float assembly and pull out the float needle valve. Hook the fuel line back to the carburetor and try the starter again, there should be fuel pumping into the float bowl. If not, check to see if there is a filter on the fuel inlet path that may be plugged. If no filter, remove the float needle seat to see if something is blocking the fuel passage. If all else fails, use compressed air to blow backwards through the needle seat (remove the fuel line again). Hope some of this helps!
