91 accord h22 swap won't start!

[Freshagen]

what ecu are you using and also have you checked your ecu fuses.

me and my brother inlaw had that same problem with his ecu not giving any spark but had fuel to the injectors and voltage at the coil but wouldn't send it through the cap and wire.I would try that and make sure that all your ecu plugs are pushed in correctly. hope you get it up and running.

thanks. I'm pretty sure my ecu fuses are good. I'll double check. I'm running a p13 btw. did you do the same checks I did as far as voltage at the coil? it just seems like it's not sending through the cap n wire like you said.

do you have a multimeter?

[GearBangnAccord]

what the voltage on your batt??? since this is a starting issue every components regarding the starting cycle needs to be examined. since i read thru and u did check alot of stuff other than the batt n starter u may may wanna check ur dizzy wiring harness inside of the cap..

Tstat ground



I would peel this back some and sand and clean. correct me if im wrong but
doesn't ground run back to the ecu.

yes i do

i'll try this

the wiring in the dizzy is good. soldered and shrinkwrapped. no cracked wires either.

swap out the ECU for a different one
Is it the OBD1 ecu or OBDII?

And if it is OBDII, is it converted over to run as OBD1?

it was OBDI I believe from the looks of it other wise it wouldn't connect.
but I agree that it might be an ecu problem.brother inlaw had this problem but
it was the NEW!! OBDII jumper that wasn't doing its job sending signal to pulse
the dizzy.(fuel,power to the to the coil,no spark) hope you fix it and open up your ecu to make sure something didn't fry.

I bought the p13 from a member on here, so it's possible... *sigh*.... I'll check up on it and report back..
What kind of signs should I be looking for when I open up the Ecu?

Does the sound of my car trying to start up sound normal to all you guys? or does it sound slow and out of time like darkcloud said? if so, what needs to be timed? possibly balance belt?

[Freshagen]

this seal was already gone when I got the ecu... did the previous owner open it up bc he too had issues with the ECU?!


this side was voided


But everything (to my eyes..) looked normal.








does this one look a little different to you?


all the pins are in tact..

I'm about to follow all the ignition wires and dizzy wires through the harness to check for breaks. I honestly doubt it since I did the voltage check with the siren and was getting voltage at the dizzy connector and at the ignitor. it's just not fuckin sending spark to the damn cap..

I'm definately about to contact the person I bought this ECU off of.. *smh

I thought you had this running before, I didn't know this was a new swap for you.

where did you source this ecu. did it come with the motor or did you piece form someone else. Are the above picture of a new one or the same one that
was placed in the car to try to start. could be your problem but do you know anyone close by that my have a spare or let you tryout their ecu on your car.

keep us posted,still have my fingers crossed for you.

[Freshagen]

i bought it from someone from this site. and those are the pictures of the p13 ecu im trying to run.

[daovangphotos]

Id come by and share my ECU, but its not a p13

Its an auto h22 ecu (P0F)


Last time i worked with an h22a4, we took it down to 2 issues: timing belt being off, and ECU. I was not there for the timing belt check, but with the ECU, we ran a OBD1 p13 in the OBD2 car.

oh ok just asking,not trying to point fingers.

have you checked the timing on all the timing marks(cams,flywheel,dizzy,tdc).
Also saw in your vid that one of your dizzy bolts was missing and was thinking
may be 180 off. have you taking off the valve cover to double check you marks.


pics of you dizzy and you wire order make sure you didn't do what my bro inlaw did last week and mixed a wire by accident lol.this is in case you do get it to start and it quiets and dies with some backfire action

[Freshagen]

yea, i'm gonna check the timing and everything tomorrow when the sun comes up.

I tried getting a spark with the old pt3, and same thing. no start. so I'm gonna double check my timing and start troubleshooting the harness next. may go to the jy and pick up an extra one to try it out just in case.
