i have a 86 fc with jspec TII swap
i just got the whole harness installed,the ecu harness rewired done
but it wont crank or start lol
did i miss anything????

 

jspec engines fuel lines are connected opposite from usdm...did you connect them right?

 

it was originally running
until i messed up on my wire tucking, so ended up replacing the whole divers side harness
now it wont crank or start, do i need to rewire anything on the dirvers side of the harness???

 

what wiring did you mess up? is the main relay wiring still good?

 

What are you calling the driver-side harness? The front harness is the larger of the two over there, and connects to all the relays, etc...Then you have the engine harness, which is smaller and connects to the CAS, coolant temp sensor, oil pressure sender and other things.

 

yeah from front to behind the dash harness that i replaced
engine harness is all good didnt touch it

i was looking at my old harness and looks like i need to rewire a pigtail that originally goes to some relays (relays are metal and near the power steering pump area) do any one know what im talking about???, need u guys help badly

 

isnt there a ground thats supposed to go on the starter/engine, thats part of that replaced harness, cant think if it is or engine harness..., id go look at mine but im at work...

 

^ Most of the starter related wires are on the engine harness, but the front harness does have the starter cut relay (on cars w/ alarms) and the start of the signal wire from the ignition switch to the starter solenoid. It goes to a plug (FE-05), then connects to the starter solenoid itself via the engine harness.

If not this, I would say the main relay plug/wiring is suspect.

 

i toke a lot of pictures today to make things easier
lmk if u guys see anything wrong in any of the pics
btw thank you to everyone for helping me out

 

i see one. your harness is f'ed up. whats with all the cut wires and spliced wires. thought you replaced the messed up harness

 

the ecu harness was like that when it was running
so i copied the old harness,thinking its gonna work
so what i have to do???
damn i feel like an idiot ...

 

i would think you need to find you another harness!

 

butt connectors....

good luck with your ordeal, i ain't even gonna bother trying to sort through this mess.

doesn't anyone in this section use goddamn solder? i'm surprised it ever ran after looking at those pics.

 

just found out this two plugs circled in yellow was switched around
but still no crank/start

 

go find a car in original condition and take pictures

 

i found blown interior fuses
ill try to get that changed this afternoon, ill let u guys know if this solves this problem

 

interior fuses just control the interior lighting and some switches.

 

Wow, you're going to need new emissions (ECU) and front harnesses. I would throw away all of that hacked up B.S. and start fresh.

 

the interior engine fuse will keep it from cranking....

 

The thing is, if any fuses blew, it's probably because of one or more shorts somewhere in the mess of re-wiring.

 

finally car is cranking
fuel harness wasent plugged in
and both coil box's wasn't grounded

the only problem now is car wont turn over???
anyone know what is the problem now??

 

i got the car to start
the only problem is i had to jump the fuel pump to the the ignition and jump the starter
what could be the problem???

 

Jumping the fuel pump test connector bypasses the fuel cut switch in the AFM. If it won't run without it, there's bound to be a problem with the wiring to/from the AFM and/or circuit opening relay. The relay is under the dash. It's yellow and black I think.
