Fuses That "Keep Blowing"
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, no one can identify the specific cause/defect which is causing your problem.
The following generic answer applies to any electrical circuit, whether in a vehicle, or in a building, or whether alternating current [AC] or direct current [DC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors. And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse or Circuit Breaker [and replacement fuses, or "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The fuse or circuit breaker is doing what it was designed, intended, and installed to do, protect the conductors and components of the circuit which it serves.
The proper "fix" is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it. Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an over-sized fuse would almost guarantee damage to the wiring and an electrical system fire.
Need to know which 20 Amp fuse is blowing.
No, you could overload the wiring and start a fire.
there is a fuse under the hood for "fuel ingtion system" # 20 amp change that im searching why my car keeps blowing the same fuse
Yes you can but you are setting yourself up for a big problem. There is a reason the 20 amp fuse is blowing. By installing a bigger fuse it allows the current that is causing the 20 amp fuse to blow to stay in for a longer period of time. This can cause excessive heating and melting of the wires on the circuit that is blowing on a 20 amp fuse. Trace the wire and find the fault. Always use the manufacturer's recommended fuse sizing for your own protection.
It is very common for the starter to be the cause of that fuse blowing.
Wrong amp of fuse
Not a good thing to do! If you are blowing 10 amp fuses, you have a problem with that circuit. Putting a 30 amp fuse in its place can do more damage.
you may want to check for a loose ground or an open wire that keeps touching other wires or your frame..-Shocker
it was the fuse. it is in the glove box it is maked (cluster) 10 amp fuse fixed it all.
Sounds like you have a short. Unless you are electronically inclined, take it to a reputible mechanic. It should be a rather quick fix.
Problem with the starter. Possibly locked up, or shorted out. Remove and test the starter.
If the 1990 Chevy Lumina is blowing the DIS 10 Amp fuse when the ignition is on, check to make sure that all wires coming from this fuse are grounded properly. Also check to make sure the starter is wired properly. There could also be a loose wire in the dash near the ignition.
