Electrical problem
1991 Mitsubishi Truck 4 cyl Two Wheel Drive Manual 136 k miles
Hey guys,
I've had my mighty max truck for only 4 months. Until recently the truck's been great. A few days ago I was goin about 25 mph and the motor just stopped. No hesitation or warning, nothing. I pulled over and noticed I had half o' tank of gas. I tried to start my vehicle with no success. After the tow home I checked my fuel pump with a hot-wire to the check connector for the fuel pump and the fuel pump turned on. Then I disconnected the fuel line at the fuel rail and noticed I had some pressure and some fuel squirting out. However, I didn't have a gauge to see the psi. Next I checked for spark and didn't seem to have any at the spark plugs or the coil. Now it seems to be the coil, the connections, or some wiring, or fuse issue. My Haynes manual doesn't have much info on the fuel injection but does have a wiring schematic for the said m.p.i. system. I have an old multi-tester for testing ohms, resistance, etc., but have never used one before. I guess it's time to learn, right? I'm gonna try to test the coil, then ?
THANKS ALOT!!!
