Hi, can you give a little bit more details please? Do you mean that you pump the accelerator to givr it more fuel? Is your car fuel injected?

Car runs rough after change fuel pump backfires its a el falcon i was driving down road and it cut out if anyone can help be great thanks

Judging by the model you listed you either live in a foreign land or have a 1960's era Ford when the Falcon model was produced in the USA. I do not see where you changed the fuel filter.

There are machines used to clean the injectors and check the spray pattern of each injector. They have approved voltage and a pressurized fuel feed (which often uses a low combustible cleaner).

Some vehicles had components which used vacuum pressure to automatically regulate fuel pressure. The part name escapes me but should show up in a component diagram for the fuel system. In some cars you need to check fuel pressure everytime you change a fuel pump.and adjust the pump pressure accordingly.

I hope this helps you.

2001 nissan sentra with QG18 engine. at cold start, it misses for about 10 seconds and then resolves.the MAF is new and plugs cleaned and injectors cleaned via fuel additive. cant imagine what it is

I would have the coolant checked for hydrocarbons. If there are hydrocarbons present you have a bad head gasket. The misfire at startup could be from coolant being in the cylinders. This would also explain the loss of coolant with no visible leaks and the inability for the cooling system to **** in coolant out of the recovery tank.

My sons ca is a 1990 nissan sentra it was running fine and he stop at a drug store he turned it off and when he come back out about 10 min later it would only crank on turn over it would not start can...

You need air, fuel, and fire to start the car. So, you need to make sure fuel is getting to the engine and you have spark. First, make sure your timing belt is not broke. Make sure the fuel pump is working. Check fuel pump fuse/relay, if it is not. You should hear it when you turn the key for a second or two. If it is working, you need to make sure it gets to the engine. If it gets fuel, check for spark. This includes spark plugs/coils, distributor, dist cap, rotor, sensors. Check the fuel first. Let me know. I will help you.

My daughter car :Nissian Sentra 2002. GXE 14.8 troubling starting

The pump does have a filter on it but you should also have an inline fuel filter somewhere underneath your car, Check the pump when you turn the ignition key on the pump should run for a second or two then shut off if you can hear it , it is working. It is rare for a vechicle not to have an inline fuel filter but there are some models that don't have one. The filters on the pumps usually don't stop up that often,it's pretty rare.I would try to replace the inline filter call and ask your local part store if they have one for it and you will know for sure. And usually if the crank sensor is bad it won't crank at all.

1999 Jeep Sport, 6 cyl , Trouble with cold starts.

The fuel is bleeding back to the tank past the check valve in the pump. The check valve is there to hold fuel in the line for the next start up. You'll have to replace the fuel pump module to correct this problem. The less fuel in the tank the better off you are when replacing the pump because you have to lower the tank. I hope this helps.
