SOURCE: I have a 1990 Subaru Legacy no spark on 3&4

perhaps you should 've checked the spark plug wire spark plug itself and the wiring going to the coil,there some many things that can cause a particular coil not to work.

Since you have already replaced the most common components that can cause a no spark condition I suspect a cam sensor error or crank and cam sensor going out of range with eachother.

This may or may not cause a check engine light on this year vehicle. If the cam sensor is working but the timing chain is severly worn (which on an 1989 which could have high mileage is entirely possible) the crank and cam sensor will get out of wack. The ECM (computer) will shut down but will not throw a code in this condition. Later model years corrected this lack of error code. Chryslers of the same year had the same issue.

I have seen many mechanics throw a lot of parts at these trying to solve this issue. Many times the vehicle will start right back up other times you have to let it sit. Without a lot of testing I cannot be sure of this, but it's worth looking into before you spend a lot of money replacing good parts. I have also seen vehicles with this problem break the timing chain prior to getting properly diagnosed and then you will be out a lot more money.

Car cranks but wont start? No spark. Changed ecm relay no help. Ignition harness is good. No fault codes. Battery is good. changed ignition relay, no help. I think its the ECM but need more info to spend...

Yes, the ECM is the last thing to replace after all other possibilities. No spark could be bad ignition coil, bad Ignition Control Module (controls the coil circuits for spark), bad plug wires, the crank and cam sensors (for ECM to determine spark timing).

Check the ICM -it can be tested at a parts store. If good, check the crank sensor.

What causes the spark controller to burn out?

Either engine computer (ecu) or ignition control module. It may have different names like power transistor unit, ICM, ECM etc. Power runs from engine computer to ignition module then that powers the coilpack/coils. Also check the ground connections as they corrode over time. If you replace any units make sure the make a great connection and use any heatsink paste required

Ignition control module problems

If any of the ignition components fail, you should get a check engine light and a trouble code for that component.
Are you getting any codes ?

My 98 deville tries to start but backfires and wont start.tried starting fluid no go.just backfires.can u help?

Check your fuel pressure, and your spark. If you have good fuel pressure and spark, then it's probably something to do with either your ECM, ICM, or timing gear set. Autozone and O'Reilly's have a fuel pressure gauge that you can put a deposit on to use it. You can ask either if they can test your specific ICM, ECM.

Code p2305 ignition coil b secondary circuit. no spark from coil on 2 cyl. replace coil and spark plug wires found and fixed broken wires for remote start

The wire for the secondary on that particular circuit has to be tested If you have a ICM that secondary has to be tested there, If it is controlled from ECM it has to be tested at the ECM, because its a secondary wire it is capable of shorting the ICM or ECM it self, you only listed the year engine size.

I was told by a toyota dealer that my ecu was bad...So I replace it and although the check engine light went out the car is still running the same(misfiring, not running on all cylinders)Help! Owner of...

If the ecm didn't fix it, I would have your ignition system checked, could be a bad ICM or a bad coil maybe. If you haven't already checked the spark plugs and spark plug wires. Did you have the ECM programmed for your car?

My 1990 riviera will run great, as you are going down the road it will shut off,but crank right backup. whats wrong?

Check the ECM part number. If it is a 1228253 that is your problem. get a 16198264 the other number does just what your car is doing. I worked at a Buick dealer and know about the problematic 1228253 ecm.

Not getting any spark with 1998 Suburban K2500 5.7 Had an issue with the battery the other day. Died on me in a parking lot. Tried jumping but would not start. Put a new battery in the next day and all...

Check the Ignition Control Module. Usually these are mounted in the base of the distributor - the distributor wire harness plugs into it. If you already changed that, then I would have the ECM ( Engine Control Module ) tested. I really hope it is the ICM - they are much cheaper than the ECM!!
Good luck and I hope this helps!!

Where is the ecm computer and directions for replacing it

I replaced my computer on a 95 Ultra. It is up under the dash behind the glove box next to the fire wall. There are three large connectors attached to it each about two inches wide. It will be easier if you remove the glove box to access it. Make sure to disconnect your battery before you pull the unit. There are two snap connectors you will have to carefully dislodge form the ecm with a flat screwdriver for it to come loose. Have patience and when you get it out make sure that you remove the little chip inside the unit under the little panel with screws. When you get the new unit install your old chip inside of it and repkace the small panel. Install is the reverse of above. The old chip is specific to YOUR CAR. The new computer won't work without it. I got a reman ecm @ Auto zone for about $110 exchange. Good luck!!!
