96 Camry 2.2 Engine Swap

[justin5717]

Hey guys, new to this forum, looking for some help. I have a 96 Camry that originally had a 2.2 in it. I swapped it out, and installed the 2.0. My problem is, I have no spark. I've checked and re-checked the wiring harness for any plugs that arent plugged in, checked all the grounds, and I cant find anything wrong. I tried buying a new coil, wires, plugs and distributor cap. Still no spark. Does anyone have anything to try or any suggestions? Any help is very appreciated.

2.0 ? 3sfe?

Well first things first your trying to connect an OBDII vehicle up to an OBD1 Harness. Did you swap the computer out?

[justin5717]

I did not. I was told that the engine would be (excpet for the axle mount on the back of the engine) pretty much a straight swap.

[Mister_Perkins]

lol .. OBD II and OBD1 are not compatible. Get yourself a 1991 or earlier 3sfe ecu and try it again.

Did you by chance end up with extra plugs that were not connected ?

If you were dropping the motor into a pre 96 vehicle it might have worked with the 5sfe ecu. Not positive though.

Keep in mind the A140E Transmission was redesigned a few times too..

In 1992-1994 they used two speed sensors with a different ecu.. In 1995 they changed the design again to use 1 speed sensor.

Not sure about Pre-1992 though. Did you bolt the 5sfe Transmission that was in the car up to the 3sfe? If so the transmission is going to go into limp mode guaranteed and will not shift correct at all. Its going to be trying to locate the second speed sensor which will not be there with the pre-96 ECU

You've already replaced everything except for the Neutral Safety Switch. Thats all thats left as far as a no-start situation goes. Since you just installed the motor the battery cables are probably fine.

The only other thing that makes your car start is the car sends a signal to the ECM Which is sent to the starter as well.

[justin5717]

The harness hasn't been swapped. Just the engine. It's pretty much an identical engine. I basically pulled the wiring harness out of the way, pulled the engine and trans out together. Bolted the new engine to the tranny and then re-installed. All the plugs were plugged back into where they were removed from.

All the components seem to be working, the starter cranks, the lights all work, the horn works, the fuel pump pumps. It just isnt getting any spark.

[Mister_Perkins]

OBD II and OBD I are different ECU's

From FSM:

The ECM monitors the engine condition by signals from each sensor, calculates the ignition timing and sends an ignition signal to the igniter. High voltage from the ignition is distributed to each spark plug in the appropriate order to generate a spark between the electrodes, which ignites the air–fuel mixture.



Your just not listening to me . lol .

Computer controls spark.

OBD II and OBD I are different

[justin5717]

I'm not sure I follow you on the OBD 1 or 2. I've done this swap once before with a 99, a 2.2 to the same 2.0 without any trouble.

I'm not sure if it is the 3sfe, it's from Japan Engines. The same one worked in the 99 camry.

[Mister_Perkins]

alright, well check out that schematic above then . Thats what gives you spark.

What year is this 2.0 out of?

Im sorry there are a couple 3sfe's so you may have an OBDII 3sfe.

my bad.

[justin5717]

A 96, but the Japanese model.

[Mister_Perkins]

ahh okay, well that particular 3sfe would be OBDII compliant . I was thinking you got a motor from a pre 96. My bad.

That schematic above that I posted will be what the spark is created by.

Check the ignitor ground

also ..

3sfe = 2.0L 4 cylinder


=============

If your getting Voltage to the ECU, try changing the ECU with a Known good ecu and try it again


=====

CHECK POWER SUPPLY TO IGNITION
COIL AND IGNITER
1. Turn ignition switch to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal.


If good:

CHECK POWER SUPPLY TO IGNITION
COIL AND IGNITER
1. Turn ignition switch to ON.
2. Check that there is battery voltage at
ignition coil positive (+) terminal.

If good:

CHECK RESISTANCE OF SIGNAL
GENERATOR (PICKUP COIL)
See page (IG–12)
G 2 and G–125–200ohm
N E and G–155–250ohm

If Good:

Check the signal between ECM and Ignitor

The ECM determines the ignition timing, turns on Tr, at a predetermined angle (’*CA) before the
desired ignition timing and outputs an ignition signal (IGT) “1” to the igniter.
Since the width of the IGT signal is constant, the dwell angle control circuit in the igniter determines
the time the control circuit starts primary current flow to the ignition coil based on the engine rpm and
ignition timing one revolution ago, that is, the time the Tr2 turns on.
When it reaches the ignition timing, the ECM turns Tr, off and outputs the IGT signal “O”.
This turns Tr2 off, interrupting the primary current flow and generating a high voltage in the secondary
coil which causes the spark plug to spark. Also, by the counter electromotive force generated when
the primary current is interrupted, the igniter sends an ignition confirmation signal (IGF) to the ECM.
The ECM stops fuel injection as a fail safe function when the lG F signal is not input to the ECM.

If thats good try another ECM

[justin5717]

Will do, is that oen of the grounds that go to the engine block or tranny?

[Mister_Perkins]

The igniter is connected inside the distributor.

[justin5717]

Is there a ground wire coming off the ignitor, or is it in the plug that plugs in the top?

[Mister_Perkins]

the igniter is connected inside the distributor and is grounded through the distributor bolts

Check wiring between ECM, distributor and igniter, only then try another ECM.

use a multimeter with continuity

Sorry to tread jack but what is benefits your trying to gain with this engine swap? power or MPG increase? funds maybe?
