like my topic saids.. i recently got a timing belt and water pump replaced...did research and it was perferrd for a oem one...so i got oem..after that was replaced i got a new alt and a new starter and a new remanufactured dizzy with new cap and rotor... i had my car converted obd-0 to obd-1 not to long ago and like now when im driving on the freeway..my car would just shut off on me.. like tottaly turn off..i dont kno what is causein this but its makin me soo mad...my friend who is a mechanic said to replace this and replace that..ok so i did..new fuel filter new spark plug oem wires...he mentioned it might be my sensors on my t-body..changed that t-body to a y8..now it still breakes down..now he said that it HAS to be my wirein on my car everyone saids its my obd0 to obd1 wireing..i had it done a blacktraxx in milpitas wehn i did the conversion..now everyone tell me what would make my car just shut off out of the blue on the freeway and take forever and ever to turn back on...please help me out!

car is a 89 civic hatch with a d16z6 y8 im..e/h/i

 

sounds like wiring to me? good luck

 

Does it seem to cut off after high reving?? I really don't know about D16z6 or y8, but my h23 does that now and I finally (after about 6 months) found out that the igniton coil needed to be replaced.

 

When it shuts off, how long does it take start back up? If it doesnt start back up, does it just sit there and crank (even try to start or just spin)? Does anything happen that coincides with it shutting off (i.e. shuts off after exactly 20 minutes of driving, shuts off only after cruising down highway but is fine around town, etc). Did the problem start happening after you had the timing belt replaced? Could you post more about excatly what happens, it will be helpful in trying to troubleshoot.

 

your fuel pump might be going out. mine worked intermittantly when it died. stranded me on the beltway one day. left car came back it started right up ran for a little while the died again. ended up towing car home. replaced fuel pump and it has'nt died since.

 

In my situation which I posted here about 4 times with no replies (maybe one or two), I would shut off on the highway, let it sit for 10-15 minutes, pull the wires off the dist. and put them back, and then it starts back up fine. The other day I went out testing it and it only seems to do it when revving high, like merging onto and expy and stuff like that. When I get on the highway I am usually in 3rd revving/speeding up until about 5500-6500 then shifting into 4th. Then about a mile or so down the road, it shuts off like the coil overheated.

 

Well, I would get a a spare spark plug, a pair of needle nose pliers, an empty 2 liter bottle and a buddy. Go for a ride and wait for it to break down, pull a plug wire and insert the spare spark plug, ground it out, crank on it while your buddy watches for spark (The reason I said bring a spre plug is so you dont have to pull it out of a hot motor and risk thread damage.) If it sparks, hook plug wire back up and move on to troubleshooting fuel pump. Remove gas cap, remove fuel return line at the firewall with the needle nose and put line in 2 liter bottle, tighten gas cap, turn key to prime pump and see if gas is priming. Im no mechanic, but thats what I would do, maybe someone can chiime in and tell me if this is a correct thing to try or if its wrong.

when it shuts off it takes like forever to start back up no matter where im at at what speeds im going..it just shuts off on me like im just cruiseing not even mashing it will juss not even bog and just turn off like you turnin your key off in the middle of driving your car and it wont start back up..try to pop it in gear to jump it to start wont even work..and yes is did start happening after i got my timing replaced

no it doesnt do that at all..it just cuts off like out of the blue even at low rpm's

 

I also vote for the coil.

my friend said the same thing too..thats the only thing i havent replacled ever since i got the car..i dont even kno if that would be the problem becuase after it breakin down on me like hella times takein forever to start back up it takes off...earlier today i was like at my house messing around with it turnin it on and off and on and off and it did start up right away then after that it wouldnt start for like ever and i un plugged the ecu and plugged it back in and it started up right away..im like 50/50 on this guessin its the fuel pump or wiring...but i changed tghe filter already havnet looked at the pump...

i had a mecanic check out my spark on my spark plugs and dizzy and he said everything is fine in the spark area...so it might just be a fuel pump problem or a wiring probelm my other friend who is somewhat a mec say it has to be a wiring problem..but i dunno..i just wish this car runs and doesn't die..

i had a dizzy on ther with a brand new coil...and it still did it..i dont think its anything in the dizzy timing area..

 

do you have good fuel pressure?

im pretty sure i do

 

Its your ignitor and/or ignition coil.

Have had this problem on all 3 of my EF's.

 

next time it dies and won't start, turn key on and loosen on of the banjo bolts at the filter or the rail. if fuel sprays out the pump is probably good. if it just trickles out it's probably bad.

but i just bought the dizzy can it go out like that fast? i bought it like 3 days ago

 

You never know man. Sometimes **** happens. Esp. with non-oem stuff.

Hell, Honda had a huge recall on our EF's.. mainly for the doorseatbelts, but the other major thing was for the ignition coil and ignitor which are def. trouble prone.

 

my vote is definetly for the main relay/fuel pump. my car did the same thing, its the main relay going bad. when your car cuts out next time, turn the key over the the postion in the ignition right before cranking. you should hear the slight humming of your fuel pump pressurizing, if its not humming its not working and there is your prob right there

 

ignition coil/ fuel pump. leaning more towards coil because it takes a while to start then turns over. Check fuel pump... if it is good then its ur coil.

 

if your car turns over but wont start when its hot its the main relay....

do me a favor, take the main relay off and stick it in your freezer... bout.... 10 minutes or so, then re install it..if the car turns over no problem. good, now drive it and when u hit normal op temp for a little bit, turn the car off, if it wont start. thats part of the problem.

but in your case the thing just simply shuts off....

do u mean the interior lights go dead as well ? like everything turns completley off ?

 

you ARE using a z6 (obd1) dizzy right?

yup thats correct i had a oem td42u fried like 2 coils due to my friend messin up my timing belt and now im using a autozone lifetime warretnyd one..

when my car dies it just dies like shut's off my motor..my music works my lights work everything works but the motor doesnt start up..im really thinkin its the main relay/fuel pump...but how do i get to the main relay and how do i kno if it is bad or going bad the part about how it gets hot and wont start im thinkin this is all corrrect from what your sayin i keep on tryin to start the car and it wont ever start i let it chill for hella days and it finally starts up...so if the motor is hot it wont turn over but if its cool the car will start right up right away..and the thing about turnin the key so it makes a noise i did that and i heard the tiny small buzzin noise..so im figurin out that maybe my fuel pump is still good
