Im not new but had to re-register well i have been without my car for a year finally got a new transmission & stage 1 clutch...Well now onto my new problem I have a 1997 Honda Civic Ex (Manual) and now it's not cranking (battery is new,alternator) i checked all my wiring everythings good...except when i turn the key it sounds like a humming noise...in the passenger side dash,Come to find out my Cooling fan was engaged while i was trying to crank no other noise or turnover etc. is occurring?

I have searched the net and nothing has related or came close any ideas Im putting it in the shop next week when i get paid it's my only car looks like im back on bike =( much respect for any help or advise!

 

Sounds like a grounding problem. Check the ground wires again, maybe the one on the transmission was left off when changing the clutch.

You can jump the starter to see if it works, unplug the small wire from the starter and run a jumper wire from the small terminal on the starter to the battery plus. When doing this have the key off, transmission in neutral, and the brake set. Stand to the side so if the car takes off despite these precautions, it won't run over you.

 

As mentioned, check whether the tranny ground wire is disconnected, loose, or corroded. If the ground is fine, next try to push start the engine. If it starts this way, then check the starter switch located at the top of the clutch pedal.

 

The fan is running continuously probably because someone has installed a jumper wire into the 2P connector of the fan switch on the thermostat housing.

 

Im learning on engines always been working on 18 wheeler trucks & service...Any help with what i need to be looking for to determine if it is? I appreciate the help everyone is giving me also tranny ground wire where do i need to look for this ground at. Im going out to see what i can find again it's like 90+ and i dont feel like riding a bike again 6 miles aghhh...

 

Locate the ECT switch and its connector on the thermostat housing. Is the switch unplugged and does the free connector have a jumper wire installed?





Check G3 and other ground connections:

 

I went out started following cables and i came across the one in the image Ground wire B (or 8) and cleaned it up got to go get a bolt but it cranked you guys are Amazing i appreciate the help so much saved me alot of money and a tow bill! Much respect Positive vibez ur way!!

 

Are you sure that the fan running isn't the A/C fan? If you have the A/C turned on and turn the key the A/C fan will turn on.
