Engine cranks but will not fire.
Engine cranks but will not fire.
A little over a year ago my truck would not start. I had let it sit for too long and the battery died. I replaced the battery and the truck finally started up. I drove it all day after that and it ran great. Started up every time, until the next morning. Since then I have not been able to get it to start. I replaced the battery, the coil, the distributor cap, the rotor, the spark plugs and cables, the starter solenoid, the starter was checked and is good (which is apparent since the engine cranks), and I even checked to see if the timing was off by twisting the distributor and trying to start the truck, but to no avail. It was proposed that since the truck sat for a year that the fuel may have “gone bad”. I took a fuel sample and the gas looks like apple juice. So, since then every time I’ve tried to start the engine throughout this troubleshooting process I’ve hooked a fuel line from the fuel pump to a gas can with fresh gas in it.
So, I’ve got spark, good gas, and air as far as I know. The engine cranks and cranks but never fires. Does anyone have any ideas of what might be going on?
Thank you.

Ground wire off or something else grounded by mistake? Also check your plugs coming out of your "electrical box" 9never can remember what it is called) to make sure everything is plugged in tightly. Same thing happened to me...something was unplugged.

The timing chain might have jumped some of the teeth on one of the sprockets. I had that happen with my 72 302. Shut it off one day, and tried to start it the next day with no luck. The nylon gear was wasted and totally screwed the timing so it wouldn't start.
