No spark from the ignition system

There is a ECM relay and a couple of fuses that goes bad in these cars, here is a guide on how test for the problem and a wiring diagram. Also see if the injectors have pulse letting you know the problem may be on the amplification side of the ignition system.

Here are the guides.

Please run some tests and get back to us so we can continue helping you.

Hello,

It sounds like the security system is enabled lets try to reset it. here is a guide to help:

Please run down this guide and report back.

Is the security light flashing still when you try and crank it over? Lets run the codes to see if it is enabled. Here is a guide:

Please run down this guide and report back.

Hello,

Okay, so it is your vehicle's Camshaft Position Sensor [CMP] that your vehicle's Power-train Control Module [PCM] uses to determine the ignition timing. In the diagrams down below I have included the wiring diagrams for your vehicle's engine management. Please check to the highlighted wiring coming from the CMP for unwanted resistance or an open.I have also included guides for these in the diagrams down below. You will have to use a Digital Multi-meter [DMM] to do this, so here is a link below to a guide explaining how to use one, if needed:

Please go through these guides and get back to us with what you are able to find out.

Thanks,

Good morning,

When you turn the key to the on position, do you have a check engine light on the cluster?

I attached a picture of the data link connector. You should have power all the time at pin 16. The picture I sent you is upside down. The pin in your car is lower row far right side pin.

I also attached the diagram for the voltage to the pin for power. Check the fuse with a test light to be sure there is power at the fuse.

let me know the results of this when you can.

Hi

So replaced cam and crank sensors? Has fuse #51 been checked? is there power to coils on RED wire? power to injectors Red wire? 9 times out of 10 this means the ECM power relay is not working here is a guide and the relay located in the diagrams below to help you find and test it.

Check out the diagrams (Below). Please let us know what you find.

Good to hear, please use 2CarPros anytime we are here to help.

If equipped with distributor, the distributor itself self produces sparks.

Try reading this guide, it will help narrow down what the problem is

Attached below is the wiring diagram for your ignition system

You got it backward.

P1320 Ignition Signal
P1605 A/T Diagnostic Communication Line

DTC P1320 - IGNITION SIGNAL
1. Check Ground Circuit
Turn ignition switch to OFF position. Disconnect power transistor harness connector. See Fig.
36. Using an ohmmeter, check continuity between power transistor harness connector terminal
"h" (Black wire) and ground. See Fig. 37. If no continuity exists, repair open in Black wire. If
continuity exists, disconnect ignition coil harness connector, check continuity between power
transistor harness connector terminal "i" and ignition coil harness connector terminal "b" (Green
wire). If no continuity exists, repair open in Green wire. If continuity exists, go to next step.
2. Check Power Supply
Turn ignition switch to ON position. Using a voltmeter, measure voltage between ignition coil
harness connector terminal "a" (Black/Red wire) and ground. See Fig. 39. If battery voltage does
not exist, repair fault in Black/Red wire as required. If battery voltage exists, go to next step.
3. Check Power Transistor Input Signal Circuit
Turn ignition switch to OFF position. Disconnect ECM harness connector. See Fig. 3. Using an
ohmmeter, check for continuity between ECM harness connector terminal No. 1 and power
transistor harness connector terminal "g" (White wire). See Fig. 4 and Fig. 37. If no continuity
exists, repair open in White wire as required. If continuity exists, inspect ignition coil and power
transistor. See the SYSTEM/COMPONENT TESTS article. Replace ignition coil and/or power
transistor as required.
4. Check Resistor Input Signal Circuit
Turn engine off. Disconnect ignition coil harness connector. See Fig. 38. Strip tape covering
resistor/condenser. Disconnect ECM harness connector. See Fig. 3. Using an ohmmeter, check
continuity between resistor/condenser harness connector terminal "c" and ignition coil harness
connector terminal "b" (Green wire). See Fig. 39 and Fig. 40. If no continuity exists, repair open
in Green wire. If continuity exists, go to next step.
5. Check continuity between resistor/condenser harness connector terminal "d" and ECM harness
connector terminal No. 2 (Yellow/Red wire). See Fig. 4 and Fig. 40. If no continuity exists,
repair open in Yellow/Red wire. If continuity exists, go to next step.
6. Check Component
Inspect resistor/condenser. Measure resistance across resistor/condenser terminals. Resistance
should be 2200 ohms. Replace resistor/condenser if necessary and perform FINAL CHECK.

DTC P1605 - AUTOMATIC TRANSMISSION (A/T) CONTROL
1. Check Input Signal Circuit
Turn ignition switch to OFF position. Disconnect ECM and A/T control unit harness connectors.
See Fig. 3 and Fig. 45. Using an ohmmeter, check continuity between ECM harness connector
terminal No. 7 and A/T control unit harness connector terminal No. 45 (Green/Orange wire). See
Fig. 4 and Fig. 46. If no continuity exists, repair open in Green/Orange wire as required. If
continuity exists, go to next step.
2. Disconnect and reconnect harness connectors in circuit and perform FINAL CHECK.
