91 4runne wont start.

I pulled out from my ally across the intersection running just fine. Let my foot off the throttle heading sown a small hill engine shuts down. Now all it does is crank no start. New ngk plugs, wires, cap, and rotor 3 days prior. Has fuel has spark. Timing belt is on don't know if in time but its not broke. Anyone have any ideas

Did you find out if the t-belt is on right? If you have fuel and spark and compression, all at the right time, it will run. Maybe not great if there is a sensor acting up, but it will run...

Fuel pressure readings? Blue or yellow spark? AFM moves freely? Where are you checking for spark?

All fuses been checked don't know actual fp. Spark is pretty week but the battery is low on charge. I haven't messed with it to much.

I would suggest you charge the battery and do some actual testing of components yourself before jumping on the forum and basically asking us to do all this for you. Research similar symptoms and threads and actually do the tests that others have already done and reported on....

Done research worked on the vehicle prior to battery drain. Only after doing what I could did I asked on the forum. But anyway. Just wondering if anyone has had same sort of problems and could offer other suggestions.

If you had no issues before tune-up, then re-check your steps.

Might try the fuel pump test jumper and see if that does anything different:
- http://www.4crawler.com/4x4/CheapTri...shtml#FuelPump

And try checking all the engine fuses. I once had my '85 act up once, engine was still running but lost all the gauges, etc. Pulled over, checked each fuse by pulling it out and inspecting and then re-installed each one, no problems were found. Started back up and everything worked like normal. I suspect a fuse terminal had oxidized in the fuse holder and lost contact. Just the act of removing and re-installing the fuse cleared off the oxidation and all was fine. That was like 14 yrs. ago and has not happened since.

You did your work, it ran fine, and then it stalled? Now you have spark, it will crank but not fire?

This JUST happened to me, I had spark, fuel and air with no firing. Turned out to be a loose ground. I would check your battery connections, make sure it doesn't move around in it's holder, and check all your frame and engine grounds to eliminate the cheap stuff. Good luck!
