Car Won't Start: Fusable Link OK guys I have electronics question. A couple of months ago my wife and I went to the mountains on vacation. When I returned I planned to change my radiator which was leaking. While in the mountains I broke my foot and had to have surgery and was off my feet for about two months. So once I'm back up and moving around I go out to start the RS so that I can move it and begin the radiator work. It won't start; no juice in the battery. I charge the battery and try to start and the black junction block by the battery starts to smoke. What I believe is a fusable link now has the smaller guage wire broken between the fuse and junction block. I spliced this back together and tried to start but no luck. The starter turns over and I have lights, HVAC fan, but not radio and the ignition is not sparking. I sure of the ignition because I removed the coil wire from the distributor and left it close enough to the post on the distributor to see if it would arc and nothing happened. I also do not hear the electric fuel pump cycle when you turn the key. Does this entire fusable link need to be changed or do you guys have any other ideas? :help: |
Re: Car Won't Start: Fusable Link Somebody has got to have some idea or experienced something similiar. |
PUMP UP THE FUSE See if you have power at the fuel pump relay pin A. This pin needs to be ‘hot’ at all times regardless of the position of the key. If it isn’t, there is an inline fuse or fusible link connected to an orange wire which you should find as you trace from the relay towards the battery. Happy Racing! :lol: If People Drove Any Slower They’d Be Going Backwards Fog lights are not driving lights. They look dorky. Turn em off slow pokes. How bout those dorks too scared to drive without headlights on in the daytime!:lmao: . . |
Re: Car Won't Start: Fusable Link Fusible links are located near the junction block you found and on the starter wires Fusible links are just a fuse in a wire to prevent surges. Go to any parts store and get a blade fuse pigtail and splice that in place of the link |
Re: Car Won't Start: Fusable Link hey neighbor. get a schematic and find where the volt drop is. use a test light to check those links. |
Re: Car Won't Start: Fusable Link pm me with an email address and i will send you the entire wiring diagram including the 7 fuseable link areas. its from my 90. |
Re: Car Won't Start: Fusable Link if you already have a schematic, disconnect the ecm, use a dvom and check power and ground at the ecm pins |

[/b] Excuse my ignorance, but where is the fuel pump relay? Is toward the rear under the car close the gas tank?:confused: |
Re: Car Won't Start: Fusable Link Near the brake booster on the firewall There should be 2-3 depending on how many fans you have. The fuel pump relay will have a red wire lead with a black connector sticking out not connected to anything Unplug it and test voltage on the orange wire, or simply supply 12v to the red wire and listen for the fuel pump to prime |

Re: Car Won't Start: Fusable Link You will need to replace the whole link. Make sure you install a link that is 4 sizes smaller than the wire it connecting to. Example, if your connecting to a 10 Gauge wire you will need to use a 14 Gauge fusable link. Hope this helps. Jason Badley |

People seem to have alot of trouble with fuse links... Im working on replacing all old power cables to new (little larger) ones to prevent problems. only have 3 fuse links left to replace / or change to regular fuses. Runned large AWG2 from battery to starter and same size from battery -> block and new cable from alternator to battery (little little bigger than stock) Just left with the 2 small fuse links from starter to fusebox and the larger fuse link to fans and injectors... Also did you solve your problem ? what was it ? its always good coming back telling if you found the problem or not. |
Re: Car Won't Start: Fusable Link I Just rewired my whole car, a 68 Camaro which i switched over to Fuel Injection. I used fuseable links and relays throughout. I read up on some stuff from Mad Electrical and it made alot a sense. Is it the best way to go? I dont know, but after reading up on everyting I decided it was the best way for me. Heres a link to the Mad web site. http://www.madelectrical.com/ I was just answering this guys Question about replacing a fuseable link. |
