So yesterday when I started the car, it cranked but didn't fire. It did start on the 2nd try. Odd, I thought. So then on m way home, I was steady at 35 mph when, for about a second, the fire went out. I had nothing. Then it came back and all was well. So I was thinking that maybe the opti was having a bad day.
Fast forward to today and the car wouldn't start. Cranked, but wouldn't fire....didn't even try. I noticed I couldn't hear the fuel pump priming. I banged on the tank with a rubber dead blow and tried again. This time I heard the fuel pump prime and the car fired, but then quit. That was the last time I could get it to fire. I also noticed the fuel gauge is pegged full. Soooo, time to cut an access above the tank? |

Yep, start with a fuel pressure gauge, and work out from there. Most Opti's just quit. Start, no start, start, I'd look first at fuel pump, then grounds for the ignition, then coil.

Like trying to start an engine with wires crossed. This seemed like fuel. When it fired and quit, it acted like it was starved for fuel. Makes sense since I can't hear the fuel pump priming. Can I get a fuel pressure test gauge at an auto parts store? Anything special that I need to look for? |
