SOURCE: engine turns over but will not start

Check the distributor and timing order to make sure it has not jumped at all from a timing malfunction.

SOURCE: Car turns over great getting fuel and spark but wont start

Spark without fuel = just spark. :) Are you getting fuel movement? You could have a bad/clogged fuel filter, bad fuel pump - could be a few things. Check to make sure you're getting fuel.

91 ford ranger 3.0 has fuel and fire wont start


Hopefully, it is just the battery. Try and jump start it to see if that works. If you do jump it successfully, drive it immediately to your preferred auto parts store and have them install a new battery.

If that doesn't work, there could be an issue with one of the components of the ignition system (ignition coil, distributor, etc). A problem here could prevent enough energy being transferred to the spark plug to ignite the engine. If it isn't the battery, then you should have it towed in to a mechanic.

88 rx7 run but wont start


The FC3S is notorious for this and fueling issues. Check all ground points, battery cables and connections. Check the draw from the starter. If the voltage drops below 10V there is not enough power for the ignition, causing weak spark. It really needs to spin over 200rpm cranking. Pop starting does not necessarily mean the compression is good. You need to make sure it cranks fast enough to get a proper compression test with rotary tester, New NGK plugs, new NGK plug wires.

Just recently bought a 2003 Mazda RX8. Everything fine until I came to set of traffic lights about 10 miles from home and the engine stalled and I could not re-start it. Got towed home and then tried the...


You say he removed the fuel pump fuse? Do you mean he changed the fuse? The fuel pump can't work without the fuse. Perhaps the fuse is blowing and causing the engine to stall and not restart. Find the fuel pump relay and swap it with another relay of the same type. Make sure the fuel pump fuse is good. If the engine starts, drive it around close to home until you think it's had time to stall out again. If it down'nt stall this time then the relay is bad and needs to be replaced.

Sounds like you have a bad glow plug relay that could cause a power spike and drain your battery,it could also take away power to the fuel pump causing the loss of power.Hope this helps you out some!!
