engine swap malfunction

[GenshiAri]

So I've been guesting it up on this forum here recently and I have got alot of solutions here until now. I just finished a f22a JDM swap from a f22a1 in my 91 Accord. It ran immaculate for around 15 miles over the course of 4 days. Yesterday I was driving home from work and just cruising not runnning it hard, and it just died. I pulled over, wouln't start, no spark I changed the distributor coil main relay ignition relay ignition coil and I've come to my last idea, dead ecu. i have ran obd with a paper clip in the jumper next to the ecu. got a zero. I am certain i'm not getting a spark screwdriver in spark plug boot all four of them. Any ideas I haven't thought of would be great. (the JDM Engine is a complete f22a6 it has the IAB on the intake the four butterfly thingys)

if the ecu is dead you wont get a cel when you turn key to on position. sure you didnt snap the timing belt?

[GenshiAri]

I sure didn't think of that so went out and checked it real quick valves are cranking

where did u find that engine. i am in need of a new f22 engine, and the jdm one would be a plus

Ebay motors 30k miles for $850 they even threw in an alternator

I would look at the timing belt dude. Is the engine spinning over faster than normal? The T-Belt drives the cam which in turn drives the distributor. So you wouldn't be getting spark.

i took the valve cover off and cranked it for a couple seconds. The cam is turning, so the timing belt can't be broke. I believe it must be electrical. I've learned that the F22A1 and F22A4 ECU's are interchangable, but the F22A6 is different maybe the A4 ECU burned up? I have an ECU for an A1 I'm going to check that one

Ignitor?

Ignitor?

Exactly what I'm thinking.

The ignitor (aka Ignition Control Module) sits inside the distributor and when it goes the car will stumble a little and then die. After it dies you won't get a spark. If you didn't have to change the distributor from your old engine to your new engine, you already have a spare. I'd take the old one and try it in your current dizzy.

I already had switched distributors. That was the first thing I did.

My thinking is that the ECU is the problem.
Second thing may be lose wires, but if CEL is not on, but there is no spark than the ECU is problem becuse if it work then he will read an error code in lack of spark fire.

Try to change it from someone who has the same engine just to check it.

I checked the ECU from my other accord and it still no spark, it's defenitly got to be a lose wire. Now the fun begins in trying to find which one

You should be running a PT6, which is a F22A6 ECU, found in 92-93 EX Accords.

You guys think a messed up O2 sensor could cause no spark symtom?

[5gwagon]

not at all
