ok so i was at work and started my car and pulled it in the bay to just mess with my interior and check my oil right as soon as i got out it cut off battery fuel pressure and starter seemed fine anyone ever had this problem i runin a dohc zc with a si trans with a pg7 in a 89 si hatch obd0 any ideas car was not hessitating or boging or misfirein engine is very healthy condition dosnt burn oil dont runs a little rich any ideas

 

anything will help

 

Does it crank over at all? You might want to explain more than just "it cut off".

 

does it start now? ignition switch? bad ground?

 

it cranks like it wants to start gets fuel its like the spark cuts on and off ill be driving it will cut out but just enough to notice it but not enough to loose speed or power its just a sudden cut then continues then ill stop and poop shuts off dosnt wind down or hesitate while driving no symtomps of anything except the cut while driving

 

I had this problem in my eg hatch witha obd2 b16 in it but still sounds similar. It turned out I had a bad ground on the motor where its grounded to the valve cover and it was causing it to lose spark and a while after I fixed it I ran into distributor problems coil pack fried from loseing and gaining voltage constantly. And if that isn't it check the resistor box for the injectors

 

for me once it was a bad ground another time it was the ignition switch. good luck!

 

yea its a bad ground. check the valve cover and tranny grounds.

 

thanks guys i guessin the ignition coil in the distributor whould be out of a 88-89 integra right

 

check the ground wire by the thermastat....

and check inside your dizzy and see if any of the wires are loose insede.

good luck.

 

i only saw 2 grounds one that went directly from the bat to the frame to the trans and the one on the vale cover ill look again tomarow idk guys will see what happens hopefully it fixes it it wigs me out it i never know when its goin to give

 

i think i have a bad distributor

 

If you take the but of a screw driver and very lightly tap on the distributor cap while the engine is running and the engine dies or bogs than you know the distributor is going bad. The B16 in my hatch kind of had the same problem and that's how I finally found out it was the distributor. I replaced the disributor and it worked fine after that.
I'm sure everybody already knows this but I've heard that Honda distributors are kind of flaky.

 

they are and it sucks lol i just pulled my cap off to find mine is a refurb so i shure it sucks more lol

 

well i tapped on the dizzy no reaction i been playin with wires under the hood tryin to get a reaction nothin happing i just had a new resinator put on my exhaust before this started happening before that it ran open header a couple of days you think that may have somethin to with it is there anything that might have effected anything while welding it was a shop that did it when i was runin open header i wonder if it vibrated anything loose but it would have shown sooner than after it got quieter

 

probably the ignition switch check that too

 

how is your main relay?

 

check your fuel presser?
if it starts then dies.
check the FPR,

 

fuel is fine i know it is i put 32 on the rail at idle or so and injectors are fine i changed the plugs today the old ones looked pretty worn just normal wear though u think that may have been it they where some old ngk R plugs seems to be runing even better than before how would i go about testing the ignition switch i wiggled the wires nothin happen should i put a multimeter on it or sumthin ps ngk iridium plugs ftw

 

are you getting spark?
check or chage your ignitor in the dizzy.

those dizzys are hard to find because they have that external cam sensor.

 

well i think i got it guys it was the plugs just too foul to use i done sevral pulls and miles of driving and no signs so far thank you guys for all your help

 

lol its back again it the distributor what part usely fails inside the distributor the coil or the control module

 

take the engine/trans grounds off, clean the contact surfaces, put back on.

 

did that already its the distributor my car missfired 3times very badly and now is misfireing while cranking unless i tap on the dizzy my grounds are all new with clean contacting points 8g wire

 

please help
