I have a 1997 acura integra ls 1.8 b18. I recently washed the engine. Was running great. A few days later I notice a difference in the way the car cranked to start. A few more days go by the problem is getting worse. It's turning over but very slowly and finally starts. I'm thinking sparks plugs or fuel pump. I know how to change the plugs but not sure where the fuel pump is. Any advice? Thanks greatly.

Cranking slower and slower has nothing to do with the fuel pump or spark plugs. It has to do with the battery and the generator recharging it. Start by measuring the battery voltage with an inexpensive digital voltmeter. A fully charged battery will read 12.6 volts. A good but discharged battery will be near 12.0 volts. If you find less than 11.0 volts, a cell is shorted and the battery must be replaced.

Measure the voltage again with the engine running. It must be between 13.75 and 14.75 volts. If it is low, suspect the voltage regulator which lives inside the generator.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
