Hi, The fuel making it run, tells that the spark is good, and there should be no reason to chase the ignition system. When you turn the key on, the fuel pump should run for a couple of seconds. If you do not hear this, or hear the pump run as you are cranking, there is a good chance the in tank pump is bad, and needs to be replaced.One thing you could try, is have someone crank the engine, and you bang on the bottom of the fuel tank, with either a hammer, or your fist. Sometimes this rattles the pump enough, to make it temporarily functional again. Good luck...Coop

I just put an engine in a 1972 VW bug just won't start firing order is fine top dead center is fine just turns but doesn't want to turn over


Hi Timothy:
Old Dude wisdom..........
- Fire at the plugs and
- Fuel in the jugs

If everything else is OK it should run. Not necessarily well, but it should run.

What to do?
1) Check for hot blue spark at the plug electrodes
2) Check for fuel in the carb.

If you have spark, give it a shot of gas into the carb, and give it a try. If it doesn't start, backfires, or catches fire, you'll need to double check the timing and plug lead firing order.

Not kidding! Don't set fire to it!.

Amc eagle repair


Get yourself some rolls of wire and a box of connectors, a pair of wire strippers and a wire end crimping tool, and replace each wire ONE at a time. Your only other option is to take the breather that you removed from the carb to put the gas in, and go find another car that it will fit. Drive that one.

1994 Chevrolet S-10, won't start. The fuel pump tests fine. Have checked all the relays we can find. Starter will fire, but acts like it isn't getting gas.


Have you checked the injectors (depending on modle) or the needle in the carb to make sure it's not sticking. If you have the carb model, pour about I/2 cup of gas into the air intake, assuming you have taken it off first, stand well back and turn over the engine. If it fires up, then dies, the carb needle is out, Take the top off the carb and you should see where the needle has been wearing against the carb, you can buy replacement needles for a few cents. if it's the inj model, it's a specialist job to clean the jets out, so you dont damage them, to only cost you more in the lng rn. be careful what ever you do.

Fuel 2000-pont. sun fire


could be the fuel pump listen near the gas tank while some one turns the key on you should hear it run. or the fuel pressure regulator must be checked with a fuel pressure gage, it could also be your computer is not telling the injectors to dump fuel into the engine. This can be checked with noid lights that plug into the wiring harness for the injectors and blink every time there is a pulse.
