i replace all the inside harnest and the engine harnest but car wont start is there anny thing i should of done before when i turn my key my fuel pump wont work and it wont crank

 

some one please help me anny body

 

you hooked something up wrong, First see you got the right things hooked up the right places and you have power where you should. This is going to be a bitch to figure out because it literally can be anything.

 

i checked all thge plug everything is ok

 

are you still running dx? that could be your prob? check main relay? check all grounds? check that you installed injector resistor? good luck

 

still wont start check everyrhing i suck at at this please help

 

i have a zc in my hath if that helps will the hf harnest work in my hatch

 

ok what you gotta do is get a tester, like a tester that actually shows voltage and continuity. then get yourself a chiltons manual or something liek that and go to the wiring pages and follow theres specs and make sure every wire is in place, it is gonna be a long and tedious project but its what you need to do. also make sure you grounds are on and clean because alot of the times the ground is what is wrong, also the grounds can get corroded so clean them off to get a good connection

for example, i just put in a motor in my car and i tried to start it and i got spark but no fuel, and i didnt hear my fuel pump priming. so i went in my chiltons manual and found something to test the main relay to see if it was good. everything check out so i knew hte main relay was good. took out my seats and tested the fuel pump connection, i had power going to the fuel pump so now i got it narrowed down to either my fuel pump is bad or my fuel pump ground is bad.

 

Check all grounds, all wiring, test battery and alternator for juice. Check spark. If you have power and you hear your fuel pump prime when you turn the key on then it's not fuel or main relay.

Tell us more. We need more information. You went from DX to HF harness? Why? Did you swap a motor?

 

maybe you messed up on the ignition switch

 

OK HERE IS THE STORY I HAVE A 89 DX HATCH I PUT A ZC
my friend tried doing my wirring and messed it all up he even broke the connecters at the ecu
i took my dash out took the harnest out and replaced it with a 90hf harnest everything plug in on the zc but under my dash i have like two plugs left over cables are green and black when i turn my key only my batterie light turns ont the check engine light and the oil light doesnt
and my car wont even crank at all my fuel pump is not priming either
would a harnest out off an ex be better i can get one for real cheap please help me i need my car really bad

 

It's HARNESS......

 

unless someone else has a better idea, this is the only advice i can give. go get a manual of some kinda, haynes, chilton, helms and a volt meter which shows voltage and continuity, then open the book to the wiring pages, they will show every wire on your wiring harness, look at the pages and just start tracing every single wire, making sure theres power when there should be and continuity between 2 points when there should be. and also the manual should tell you where those extra wires you have go.

 

what book is the best

 

i bought a chilton dont really understand it but ill give it a try

 

Im gonna bet this is your problem. The hf harness is wired different on the dizzy. check this out and see if you can figure it out. Might help with something


I recently converted to obd1 and i had problems with my distributor wiring. So after figuring out my color combo it started right up.

Does it act like it wants to like every other turn?

Hope this helps...

 

You might also want to check the clutch safety switch. on the 88-89 cars they did not come with them. So look around where the clutch is and there should be a plug hanging out. Cut off the plug and conneect the two wires.

THis was the same problem my friend had.

 

well my 89 hatch has the clutch safety switch do i still cut the wires
what color are the wires i have a plug left over and it is green and black

 

if your running a zc motor then their is your problem because for 1 hf harness is different.

see HF's ARE mpfi but u cant switch distributors from hf to si or visa versa.. in other words u need a ex or si harness, my guess would be si

 

well i can get a harness off an ex that had a zc beforer would that work better i can get it for real cheap thanks everybody i think itshelping me

 

well i got an ex harness im going to put it in tomorrow i hope it works it came off an 4 gen ex with a zc

 

im still having the same problem i need help bad

 

Check the fuses. Check and make sure ya plugged in the ecu...i did that once check the relays, check all the lil things you would over look.

 

you may have a bad ecu you could of fried it when you put the new harrness in

 

ps just try a friend ecu
