I keep changing the fuse and it instantly keeps blowing out. i change the crankshaft, crankshaft sensor and the crrms relay module. nothing works. it all started after i got my front and rear tranmission seals done. HELP ME PLZ
Have you checked that the starter itself has not been grounded out (short in the wiring?)
The chances are this is what is causing your problem, start at the starter motor & follow the wires, check every single one, if you have a bare section that comes in contact with the body or anything else metal it will ground out that wire & cause the fuse to blow every single time even if you were to double the fuse resistance I.E. if the fuse is a 20 & you put in a 40 it will still blow - that last part is ill advice - never put a higher amperage fuse in a socket that was intended for a lower amperage fuse - it could cause a fire & serious injury, check all your wiring from the starter you have a short in the system somewhere it's just a pain in the a

SOURCE: 2008 Ford F450 fuel pump relay fuse keeps blowing.
the fuel pump and radio are not on the same circuit, most liokely the fuel pump is shorted, that is the most common cause, get under the truck and disconnect the fuel pump connector at the tank, if the fuse doesn't blow then u need a new pump.

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: keep blowing the starter relay fuse on my 1995 ford ranger
Had similiar problem on a old Austin Alegro 25 years ago.
2 reasons.
Starter had worn wire insulation. Used industrial yelow sticker foil on that.
Fuse blow in sane curve highway every time. Car was repainted and wire harness reinstalled unprofessionally previous owner.
Crawled half a day every square mm and yep a litle broke insulation on a positive cable grounding to chassis an blowing the fuse.

I would listen for the fuel pump(take the gas cap off and listen for the buzz when someone turns the key on), if no buzz or whine then have them crank the engine.If still no noise then take a hammer and hit the middle of the gas tank while the car is being started(make sure E-brake is applied)If it starts it's your fuel pump.

I understand that there is a relay box under the hood with 3 relays. Which is which I don't know. However if you are blowing the fuse TO the ecc relay, then the relay must be bad. This relay controls the spark.
