Hook the battery up or try to jump-start backwards did we?
\015\012The ECU fuse gets it's power from the 140 Amp (or 180 Amp, depending on which engine your vehicle is equipped with) ALTERNATOR fuse in the engine compartment fuse block.
Hello and welcome to FixYa!\015\012
\015\012It gets power from the ecu relay. It may not start at first specially after battery replacement for it's relearning itself. Once the computer relearned itself the vehicle may work normally again. Touching the ECU fuse may have jumpstart the ECU that's why it worked after.\015\012

I was working on tail lights on 2004 dodge 1500 I ran a wire from hot side of park lamp fuse (inside cab fuse panel) to tail light connector.The alligator clip of my wire laid against the chrome step bar the wire burned (small gauge wire maybe 16 awg) in half, not the insulation but the wire inside. Now the truck wont start, engine cranks good I have fire at spark plugs. I also checked fuses and relays under the hood fuse panel and inside cab fuse panel.


Do you have fuel? You might want to check the fuel pump fuse and see if it took a hit!\015\012\015\012You could also spray a little starting fluid into the intake while cranking and see if it sputters.\015\012\015\012Good luc ... Dodge Ram 1500

Electrical Problems Started truck (very hot day). Instrument panel stopped working except RPM guage. ABS and Air bag lights came on. The A/C, Power windows/locks, radio, blinker lights, etc all stopped working but truck kept running. When I shut it down and tried to start later the truck didn;t start. Make a clicking noise like the battery was dead. Can't start to get over and run the tester at Auto parts store. Possibly a fuse or relay? Any ideas ???


A mechanic would start at the battery and test the circuits. If you have lights but no crank, could be a dirty connection at the battery or a dead cell in the battery. If that checks out ok, look at the fuseable links. ... Cars & Trucks

98 chevy k1500 my keys touched a hot wire inside the steering colum while starting, sparked and key got hot while pulling it out as fast as i could. Now blower ,radio,and wipers don't work. All fuses are good,not sure about the relays. I dont think one relay would go to those. Cheked wires that go into key cylinder, they appear ok but do you think if burnt on inside it would only effect those 3 items? This is a tough on for me to diagnose please help, thank you. Joel

I recently purchased an 01 Passat V6 4motion. The current problem with it is it will not start, cranks fine, but will not turn over. Upon my findings I've noticed I am not receiving power to fuse 28 as well as fuse 29. I have purchased a new fuel pump relay and re-spliced the wires leading into my comfort control module still no luck. When I jump the fuel pump relay, power comes to fuse 28, and 29, but still will not run. ECU is getting power, the 40 amp fuse is good and relay 373 (next to ECU)

I just bought a 2000 ford taurus. It would not start or crank over.I noticed the ign.key had a lincoln key logo. I bought a new pats taurus key. It still did'nt turn over.

Hello, I replaced the starter selenoid on my 1990 F150, 6 cyl. truck because it would just buzz and not start. It ran for awhile. I went to start it and the rpm was very high.
