not my car but im workin on it.....It gots a b16a swap...so what happened was the dude that owns the car was driving with no battery stay and .....guess what...battery tiped over and grounded out now car wont start...it starts with starter fluid then dies out....fuel pump works can hear it pumpin away...got spark and as far as i no got fuel to motor...wut else could be wrong.... help plz!!

 

Have you checked all the fuses and visually inspected the wiring harness for damage?

 

done all that no fuses were fried sum little homemade bs ground wires were torched and thats about it no visible damage to the harness

Ground wires are important. Did you replace the ones that were fried?

Are there any CELs?

 

these ones were not important they were as thin as speaker wire... the main ground is enough to start it and it was fine

OK, whatever you say. They're still important.

Not if the owner added rice straps though.....


Grounding out the battery with the cables on can fry the ECU.....

 

i no thats wut im afraid of...shouldnt the ecu fuse go out b4 the ecu gets messed up...and would it start with a bad ecu? bc it starts with starter fluid and idles but once i stop puting starter fluid it dies out

 

I just got my 1990 civic si legit today smoged, registered, and new pipes. Well i was driving went over a bump slow as possbile. The battery wasnt strapped down. It turned over on its side and shorted out the battery and the fuel pump. the ecu fuse is fine as well as all the others. The fuel pump was ran right to the ecu and a simple kill switch was wired to it. Relays never worked so i guess the guy ran it stright to the ecu. I replaced the fuel pump, it primes over and everything still no fuel getting to the motor. all hoses are in the proper place. The ecu is flashing once and than 3 secs later 7 more times. o2 sensor, and i think tpc. But thats obd1 the harness and ecu is obd0(b16ecu). The motor is a 2nd gen jdm b16a. The car starts up with starter fluid and dies out when not being sprayed with the fluid. So that simple test imo means its a fuel problem?? or maby someone can give me some help!

 

Its my car

 

The problem isnt electric imo, its fuel.

 

the fuel system is electrical....just go get a ecu

But The fukin pump is workin we re not having problems getting the fuel pump to work its getting the ****** fuel to thr motor! &lt;3 uncle

 

see if the ignitor and injectors have power.

 

OH YEA... and check where the wiring harness grounds on the thermostat housing the wire is thin and could smoke easily.

will do

 

nada ...jay im leavin to the ball game when i get bak i guess we'll check it out... later

 

alright man thanks im headed over to the garage now. cya brada

Obviously the main relay is working. The main relay sends power to the fuel pump and the ECU. You've determined that the fuel pump is running - but that doesn't mean the ECU is working, because the injectors aren't spraying. The problem must lie between the ECU and the injectors.

That idiot is lucky the battery didn't start a fire and burn the car down when it tipped over.

Wow, what a clusterf*ck.

Good luck with that hacked together piece of ****. Why do people ruin their cars by messing with the wiring? Not only does it serve no purpose, it also makes it impossible to follow electrical troubleshooting procedures outlined in the factory service manual.

The car is getting spark but no fuel (the fact that it runs on starter fluid indicates that).

 

If i would known that the pump was ran to the ecu i wouldnt have bought the car! Now im fucked. I just spent $600 on the car yesterday smog,reg,pipes, tuneup! I really need some detailed imformation on how i can check if the ecu is bad/good, if the injectors are getting power and how should i go about this.(shitty wiring)

 

wouldnt the ecu's fuse go out before the ecu? Or because of the fact that the f*ckin guy i bought it from is an idiot and ran the pump to the ecu, shorted the pump= shorted the ecu?

 

The fuel pump primes when you first turn on the key right? but does it run while cranking? check to make sure its getting 12 volts while cranking not just when you first turn the key. if it is then the injectors are not working( which can also be ECU). if its not getting 12 volts then its a ECU/messed up wires issue. every thing will seem to come back to the ECU or that messed up wire mess the last owner did. can you get a loaner ECU to try?
