91 civic hatch. D15B. DPFI to MPFI. i have 2 grounds valve cover and near the thermostat. i already checked the spark. Any suggestions? thanks in advance.

 

bump. anyone?

 

I am assuming you had spark? It says you checked it, but didn't say either way, just curious.

Do you hear the fuel pump prime? Have you checked to see if you are getting fuel to the motor? If not, pull off the return line from the fuel pressure regulator on the rail. If none there try and the fuel filter.

 

Hey

Normaly when i have a issue with a car that dont start i have three steps that i take:

1st. check if there is spark at the spark plugs.
2nd. Check if there is fuel spraying out of the injectors by swinging the engine.
3rd. Check if there is compression in all cylinders.

If there is nothing at Step 1,2 or 3 then work your way back to the components.

e.g fuel not spraying out of the injectors check the common rail if there is fuel in there...

 

What exactly did you rebuild?

 

wer getting a spark. myy uncle and i wer figuring wats the problem. the fuel pump might be the problem cuz he tested it with the volt meter. he also tried something w/ the relay. Also, we tried to start it w/ the starting fluid. we sprayed it at the intake. Thanks for the support

We have 1 and 3. my uncle and i opened opened the nut. but it didnt work. the fuel pump is not pump the gas. and the fuel pump cost $$$$$$$$$$$$$$$$$$140.00$$$$$$$$$$$$ cheapest one.

Forgive me. i thought it was a rebuild. but it wasnt.

 

bump... still cant figure it out. i checked the sparks and compression.. i opened the fuel rail and tried to start it with the starter fluid. still didnt.. is the the fuel pump? or grounds? wires? i havent done anything for the past 5 weeks..

 

So no gas is coming out of the nut on the fuel filter when you prime the car? Have you checked your main relay under the dash? If you aren't sure where at that is check out this site. http://techauto.awardspace.com/mainrelay.html

When you first turn the car on, does the CEL come on (you will hear a click and your pump prime) and then it will stay on for 2 seconds and then another click and the light will go off.

 

Check the timing.

 

Yeah check your timing, and put a ground on your starter.

 

Yeah, no gas. we checked the main relay to make sure. and we heard a click.

How am i going to check the timing? i mean where? sorry, im just new to cars and im only 17.

I have 2 grounds already. would that be ok? wer tryna figure if the fuel pump is the problem or we have no grounds to the fuel. (i dont know how to state it) the fuel pump cost $140ish.

 

search TDC (top dead center) and make sure all the lines on your crank and cams line up correctly.

 

^ gotcha. i'll let you know. thanks to you all :D
