I have a 1988 Civic DX 4 door sedan with a 1.5 engine and dual point PGM-FI fuel injection. This car has been sitting for the better part of a year outside here in S. Jersey. I jumped the battery and drove it into the garage where I charged the battery with a 2 amp charger overnight. Took the charger off this am and It started right up and I moved it out to the driveway where I left it running and tested the heater and radio etc. while I waited for a buddy of mine to come over and follow me out to the country so I could rev up the battery in third gear at 50mph for awhile without worrying about killing the engine and getting stranded. While waiting I thought I’d take it around the block and work some of the kinks out. I put it in gear and the engine stalled. I tried restarting it and it cranks but doesn’t start. Bought a can of starting spray and shot some into the butterfly valve and still nothing. It spits fuel out and tries to turn over and then I get a clunk and nothing. I get the 3 clicks, the check engine light and brake lights come on. This car has 108,000 miles on it. I had the ignition igniter changed in 92 or 93 I think. Would error codes show up on the ECU for this problem and where do I find the ECU on this model car? I’m supposed to be selling it tomorrow so I’d sure like to get it running for the buyer. Any help would be greatly appreciated.
