My 1990 Acura Integra GS will not start. The ignition cranks and turns just fine. It sounds like it will start but it wont catch. I have replaced the battery and connectors, main relay fuse, have had a tune up, and have ran Lucas fuel injection cleaner through it but this has kept randomly occuring now for around a year. It used to take about 10-15 minutes if I left it alone and then it would start but it has been four days this time, worked fine for 3 days prior to that but was unstartable for the 6 days prior to that, but started just fine for the 3 weeks prior to that. I think it could be electrical wiring but the scopes show all is ok. The car also beeps at me on occasion, often for a day or two at a time but then no beeps for months until it just starts up again. The wipers only work on one speed now (i don't know why) and the rear defogger (which also worked at random) is no longer functioning. I cannot afford to keep replacing parts that do not need replacing but I also cannot afford to go without my vehicle. I cannot afford a different car at this time and I desperately need my car for work and the kids. When it will start, it runs great and has been a dependable little car for the last 6 years, despite it's quirks. Can you help to diagnose the problem or at least point me in the best direction as far as fuel, electrical, etc.?
