F22B1 Will Not Start...

[DGOfTheCentury]

What's up guys...here again. I could really use some help from the experts on this site. Ok so I have a 91 Accord with a F22B1 swap. Just recently I ordered another engine harness which is just the harness around the motor.

Just finished installing it today, however now it will not start. The new harness came with a couple of connectors I did not recognize so I just left them unplugged because I have no use for them.

I just need a list of what is vital to the start of this motor, because I had it running before...idk what I might of missed this time around. BTW I have a POA-A01 ecu. The engine harness is a stock 91 Accord Ex M/T harness.

if you are using the F22B1 harness from the car that the motor came from, then it isn't going to work in your car - you need to use ALL of your original '91 wiring. The new motor should not include any wiring at all - just the motor and metal accessories. You will need to make minor adjustments to your wiring to match up to the new accessories (like the distributor or whatever) but at least you know the main wiring matches the rest of your car.

if you tried to use a harness from another car, it will match up to the engine, but won't mate up to your car. You'll be left with some of the main harness connectors being left disconnected, which is the equivalent of completely disconnecting entire sections of your engine (like, miss one connection, and your entire distributor and transmission are no longer connected... miss another one, and the entire Intake manifold is disconnected...)

Make sure the ground wires on the thermostat housing are good and tight an making connection. Check your ecu fuse aswell.

Dude I'm not using the 94 accord harness f22b1...I'm using the 91 accord f22ax harness...

Pretty sure the grounds are making good connection, when you say thermostat housing do you mean the ground right below it? Or should it be grounded to the housing?...where would this ecu fuse be located? Also I have an oil light on the cluster when I put the key in the on position though I have plenty of oil if that means anything. She cranks but I can not get her to start.

Can you hear the fuel pump kicking on and are you getting spark?

Sorry, I need to learn how to read

Oh think tht ground is on the back of the block below the thermostat housing...but I will switch it around tomorrow and give it a go...

No I do not hear the fuel pump...
How loud would the pump be? I should hear it when I put the key in the on position right?...the way I checked the fuel pressure...I squeezed the feed line with my hand felt pretty solid

There is a few sensors I do not have hooked up...like the EGR, Idle Air Control, and whatever sensor is to the left of the MAP sensor when you are in front of the throttle body...my MAP is on top of the throttle body

Ok, let's see if I got this right.

- 91 manual wire harness
- 94 F22B1
- 91 CB chassis
- POA-A01 ecu

First off, is the chassis originally a manual or automatic?

Secondly, did you do the A6-11 mod?

Can you take pictures of the unplugged connectors. You should be using them all and adding a VTEC harness. That sensor to the left of the map on the throttle body sounds like the TPS. That needs to be plugged in.

To the best of my knowledge she has always been manual.

Not sure if I did the A6 to A11...if I remember correctly it was optional

Will get those pictures to you asap.

Took a couple of pictures before I had to be to class. Pictures of the sensors and connectors I have just hanging out.

Plug in that TPS sensor. She should start then.

Bad and good new...discovered my problem

Would appear the ECU is fried lol

Had a recent thread about a water leak I was having...I did not know it was this bad. It would seem that the water got to my ecu.
Going to go to the pick a part and search for another one...if it does not start after this...then I will splice the harness so the TPS can be plugged in as well.

Pretty sure this is my problem...I have fuel, sparks are good, fuel injectors are brand new, starter works like a dream...the car should at least sound like it is going to come on with all that...but all I can hear is the starter...off to pick a part

Hard to believe that you would have spark with a fried ECU.

when i said "sparks" i was using slang for the plugs...but everyone loves a little sarcasm...
