coil tested OK, and a new one substituted to check...don't know where I'd find another ECU:-?

everyone says try this Department: Good day sir, here is the email requested. Vehicle arrived at shop by tow truck. Vehicle at first would start every time.. ( noticed left rear brake line leaking and advised customer/left rear tire).. unable to duplicate no start concern.. after 3rd or 4th day finally got the vehicle not to start. Checked compression( cyl #1 135psi, cyl #2 130psi, cyl3 and 4 at 135psi(slightly low but not low enough to cause a problem) Checked for fuel, did have correct fuel pressure), vehicle was getting no spark( to the plugs). Spark was coming from the coil to the distributor(nothing from distributor to plugs). Checked power and ground to distributor, to make sure when vehicle cranking over, ecm saw signal.. it did not. The crank angle sensor on the distributor was not showing output. Took timing belt covers off to be sure everything ok. No concerns, no slip/break, all within specs. Tested with known good distributor at this point. Vehicle started at that point but ran for about 10 seconds then shut off. Again, no spark to plugs. Retested everything as before, then found no spark coming from ignition coil. Checked resistance in the coil to see if ok( primary side had .8 ohms and spec is .8-5 ohms/ checked secondary side.. had 17.1 kohms.. spec is 8-12kohms). at this point installed and tested with a known good coil. Oem coil went to .9 on primary and secondary went to 11kohms. still no spark from coil. At this point all specs are within ranges on all systems and no spark from coil. At this point is where the trail ended. Yes, post it in the "Older Generation" Note: the dealer has had the car for over a month, tested it with new distributor, new coil, etc., and still has not got it to keep running. There is/has been intermittant spark. I thought it might be a ground or possible bad wire/connection from the ignition module, but they haven't found any so far. Car went in 9/23... still there, but they said "come get it, we quit":-( 1991 Subaru Loyale wagon: 220,979 mi. (1428 since new timing belts). VIN JF1AN4220MB417193 Car ran very well before it quit... no oil consumption, excellent acceleration, no misfiring. It has been well maintained. Like This Quote MultiQuote Edit
