If the leads or not correct for the firing order you will have a pronounced miss/ back fire or hard to start. If the fuse to the fuel pump keeps blowing then the pump is shorting out or is drawing too much current in it's operation. Acceleration will demand a plentiful supply of fuel and if the pump is having problems replace the pump . have the fault codes read and have a fuel pressure test done on the fuel manifold to check -filter and fuel regulator operation

SOURCE: E.E.C fuse keeps blowing in 1991 Ford Explorer

if you replaced fuel pump i would look at backward wiring when replaced and i would start at the source of work if your vehicle was working fine before replacement then 9 out of 10 it will be your fuel pump wireing

sometimes when putting wireing back together the connectors have the missing clip and in turn you can turn the wireing in both directions now where positive is touching the ground on both sides of connector kris kross problem check your work this is crucial use a test light to find the right wires where they go

SOURCE: fuel pump fuse blows

Check the fuel pump relay, i am not sure but i think there are two of them. Check the wire harness too, mice may have chewed in to the wires causing a shot in the system. 
Good luck and hope this helps.

SOURCE: fuel pump fuse blowing

replace the fuel pump, it is drawing to much current, this is common when the pump bearings get worn out, also make sure you replace the fuel pump connector at the fuel tank connection, it will be burnt..

Fuse s under hood keeps blowing. It is the inj/coil fuse

Try jumping the starter with the key on. If it doesn't blow. Check the start wire for chafing and grounding out. You can pull the starter relay, Try to start it, see if it blows,yes, it is between the fuse panel and fuel pump. no. Put it in and pull the fuel pump relay. Start it. If it blows, then it is some where between the fuse panel and starter. If you have one of those intelligent fuse panels, it could be that also. You can have the codes read for it. But it takes a scanner, not a code reader.

Ive got a 1967 Firebird with a 1968 pontiac 350 in it. It's got a problem that when you try to excellerate it just stumbles all over it self and cant get any power.

check for 2 wires crossed in the firing order --will start and idle ok but plays up when accelerated
check the power valve and the accelerator pump systems in the carby
( new means nothing and back fires destroys power valves)
use lead separators to keep ht leads apart
static btd timing has to be no more than recommended as it will cause problems at rpms.
if you have a points system the point gap and condenser are critical as well

Why does the 20amp fuse for the fuel pump keep popping?

rodeo or rodeo SPORT?
2.2 or 3.2 engine> not even a cylinder count....
i wish all problems were this simple. (easy with ammeter)
the load is SHORTEd, the fuse saved the fire.
x2 all above answers
but keep in mind some fuses run more that one thing, ill check.

20amp fuse (no label) no engine option stated, must be the 6ve1, v6 twin cam.
fuel systems vary by (engine type)
not the 3.5L vin Y engines. 2.2 or 3.2L>?
fuse EB12, Engine bay fuse blows, 20a, fuel pump.

so pull these conn.
H-15 first
then if ok, (no blow)
H-25: if not blow now the pump is shorted
or the wire from H25 to F1 is ground to the frame.
wire inspections are first. on that path.
i use a EB12 , circuit breaker and mag ammeter to find this fast.

Hi idil then died wont fire up

The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems.

Van idles fine but when going the the road giving it gas it acts as if it isn't getting the proper gas ... it back fires....repleaced fuel filter and pump, crank and cam sensior

sounds like the timing is off. check the firing order to be sure your plug wires are on the correct positions on the coil packs. if that checks out, possibly a timing chain may need replaced. i hope this helps

Wireing a new fuel pump in a gq patrol , cant wire up fuel pump properly keeps on blowing fuses and fuel pump not working

If you keep blowing fuses you need to trace those wires back to the Engine area and find the short that is causing that. Start at the tank and work your way forward.

Sounds like a dead short on a low amp cicuit. If it doesn't buck when you don't use the turn signals. Then it is a short. this could interfere with the electric gas pump. If the two problems are unrelated, confirm firing order of the spark plugs and check s/p leads.

there is no safety switch beside the fuses and relays how did you replace an engine, did you rebuilt it from top to bottom or did you just put another used motor in? if you replace it with another motor assuming you did not mess with the timing such as the belt and the camshaft, check and make sure you getting fire from spark plugs, having a friend turn the engine over and you observing the plug. by pulling one wire with the plug and ground it and turn the engine over and see if you getting any sparks, second check and make sure you getting plenty of fuel to the fuel filter and the fuel pump is working properly. no fuel to the filter, check fuel pump, good pump, faulty crank sensor. that is the first two thing need to be check, fuel and sparks. if no sparks, check coil if its good and putting out 12V, if its not, check the cam sensor, may be faulty. faulty cam sensor will not make spark plugs fire. if you are getting sparks and fire, than it out of timing, rotate the distributor forward or backward with small movement no more than a tip of a car key at a time, when you capture the running or sputtering of the engine, movement should be no more the a pencil lead forward or backward. without using a timing gun the best way to know if you have the engine on correct but close timing if you able to crank/start the engine and it fire right up without keeping the key turn.
