Fuel is fine. Replaced 12 volt to coil. 12 volt to coil but no spark to distributor or to spark plug.

Welcome to 2CarPros.

I believe there is a pick up coil in the distributor on this vehicle. If it fails, you will lose spark. Check to make sure it isn't corroded or rusted.

Next, I need you to pull diagnostic trouble codes. Here is a link that explains how to do it on this vehicle:

Let me know what you find.

Hello Joe,
I did get to hookup my OBD I, and there were not codes to scan. I did replace the coil because I found oil in where the spark wire plugs in. And for the pickup coil, according to the Hayne book it is a photo-optic sensing unit in which I never seen one as such and there is no way of doing any diagnostic testing, so I ordered one through O'Reilly's auto parts and will be receiving the part in a couple of days.
Hopefully that will do the trick.

Welcome back:

I thought that one had the pick up coil. Let me know if that takes care of the issue.

Let me know.

Hello Joe,

Well, I went ahead and install the photo-optic/pickup coil and the problem persist. Though the meter indicates there is 12 volt on both sides of the ignition coil when the key is in the starting position, no spark is coming out of the ignition coil to the distributor. I have changed the wire in the event it has a defect thou it only 4 months old.
I did check the fuel line going into the rail but nothing sprayed out when turning the ignition key on or cranking it over. Next step is to check the fuel pump. I did spray ether into EFI port but no fire in the hole.
Any thoughts?
Thanks.

Hello again,
I forgot to mention that I had replaced the ASD relay but did not check to see if current was going to it.
Next item to check!

Welcome back:

Do me a favor, try this test and let me know what you find. The picture attached correlates with the test.

Before proceeding with this test, perform "Ignition System Starting Test." Failure to do so may lead to unnecessary diagnostic time and incorrect test results.
1. Measure battery voltage using a suitable voltmeter. Battery voltage must be at least 12.4 volts to deliver the necessary voltage to operate the cranking and ignition system properly.
2. Crank engine for five seconds while noting voltage at coil (+) terminal.
3. If voltage does not remain near battery voltage during cranking, problem is contained within the SBEC engine electronics. Refer to the appropriate chapter in the "Fuel Injection Section" for diagnosis.
4. If voltage remains near battery voltage during cranking, turn ignition Off and disconnect 60-way electrical connector, from SBEC and inspect connector for any loose terminals.
5. Remove coil (+) lead, then connect suitable jumper wire between battery (+) and coil (+) terminals.
6. Momentarily ground terminal 19 of 14-way connector using a suitable jumper wire, Fig. 2. A spark should be present when ground is removed.
7. If a spark is present, replace SBEC. If spark is not present, use special jumper to directly ground coil (-) terminal.
8. If spark is present, locate and repair open in wiring harness. If spark is not present, replace ignition coil.

Also, let me know if you tried to get diagnostic trouble codes following the link above.

Hello Joe,
when I perform this test, is the connector to the SMEC connected or disconnected to the SMEC once I have located pin 19 and does the ignition key position involved in this test?
I have perform the as described on the link and code 55 displayed.

Thanks,
Rios.

Hello Joe,

Today I had more time to spend on the Acclaim. I process to start the you have requested, I had removed the 60 plug connector and found very odd the 19th pin was recessed in the connector. Once I tried to attach the connector to the SMEC the pin would not seat in it port. I push it in with needle nose pliers and the vehicle started right way. To correct the pin from falling out, the casing to the SMEC has a inch wide plastic guard for the wire harness so I drilled two holes and secured the harness with a zip-ty so it won't move and keep the pin in place.
Thanks again for the help and saving me the time from wasting it on the fuel system.

Rios.
