The vehicle runs fine when it starts, according to whether or not the fuel pump activates. More prone to starting problems in the winter months(moisture?). FUEL PUMP ACTIVATES INTERMITTENTLY. Vehicle has new fuel pump, new PGM-FI relay, new ignition electrical switch assembly, new ECM(not aftermarket), fuse # 18 under dash OK, ECU fuse under hood OK, fuel pump ignites when I jump terminals #5 & #7 at the PGM-FI relay connector w/ ignition key in start position. Have performed fuel pump and PGKM-FI tests from Honda Civic Service Manual, 1995 1st edition, section 1, pages 11-127 thru 11-130. All tests are positive going thru the trouble shooting flow chart. Sometimes the vehicle will start w/ no problem what-so-ever.

Those tests only matter if they are performed while the problem is present. They had a real lot of problems with that PGM-FI relay during those years. This sounds like a fuel pump or the distributor has gone out. When you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds?

Are you suggesting that I try another known working PGM-FI relay?

You could but the point I was making is that you have to test while the problem is present.
